Innovation, similar to communication, which I touched on in the previous issue of Tyre Trends, is a somewhat elusive subject as far as modern organisations are concerned. My intention here is not to delve into the subject’s intricacies but to share my experiences and views with the readers.

I do not know if I am the best person to touch on customer psyche from a marketing perspective. However, on thinking widely and looking at the big picture, I feel I am not very far from the truth that we are all engaged in putting our ideas across and understanding, or very often misunderstanding, relationships and dependencies throughout our lives, be it in family or social and business circles. In other words, we are marketers in the sense that we seek agreement to our views and expect a positive response from those with whom we associate. The Buddha, in one of his discourses, has indicated that the world depends 100 percent on relationships. This is equally applicable to all phenomena in nature, including human relationships. The quality of the relationships is the key determinant of the success or failure of the quality of any human activity. On thinking broadly, quality is a rather evasive term with a wide variety of interpretations, reminding us of the proverbial ‘seven blind men and the elephant’. 

My experience with the ISO certifications naturally prompts me to seek information from the ISO standards. A widely accepted and general definition of quality is the level to which requirements are fulfilled. According to the ISO 9001:2015 QMS, the customer requirements are broadly categorised as: (a) stated requirements, (b) implied requirements and (c) compliance obligations dealing with statutory and regulatory, and other legal requirements. Requirements stated by the customers are apparently straightforward but may need careful evaluation, while the implied requirements need to be invariably derived using the available information and the experience of the supplier or the manufacturer.

At the very beginning, the ISO 9001:2015 standard gives top priority to understanding the context of the organisation, which takes in to account the external and internal issues as well as the expectations of the external and internal interested parties while assessing the business risks and opportunities associated with the same. It is rather discouraging to note that many companies do not pay the due attention to Clause 4.0 in their quality management systems.

The concept of ‘internal customer’ is another important area that is apparently taken for granted in many companies despite the complex dependency and the independency between the processes and the process owners. The several ‘meetings’ that the managers are frequently engaged in – to the level of becoming a malady – could be the outcome of not paying attention to the ‘internal customer’. Habits 4, 5 and 6 of Stephen Covey’s ‘The 7 Habits of Highly Effective People’, namely Think Win/Win; Seek First to Understand, Then to Be Understood and Synergize, can be of valuable guidance in interpersonal relationships. Not understanding the requirements of the ’internal customer’ or the next in line in the value adding process has created closed domains and ivory towers within organisations.

As I have mentioned in one of my previous articles, ‘social distancing’ cannot be considered as post-Covid addition to our vocabulary. Its origins can be traced back to the post industrial revolution, when the traditional craftsmanship and cottage industries gave way for mass production system, which simultaneously resulted in mass de-personalisation. Individual craftsmanship was the norm in my native village in Sri Lanka (then Ceylon) in the fifties. I presume that some of the surviving ‘baby boomers’ can recollect similar experiences in their own countries. Pride of ownership and personal reputation were considered in high esteem – sometimes even at the expense of a little extra profit..

Notwithstanding the tremendous benefits accrued by way of increasing the agility and responsiveness with tools and conveniences of modern communications in the modern organisations, the distancing of relationships has introduced new problems. The importance given to the ‘personal touch’ appears to be the hallmark of an extinct species.

On the same lines, I remember an episode from my days in Nairobi, Kenya in the early nineties, how the owner of a well-known chain of hotels got his Harvard MBA son to work in a hotel kitchen as his first job and set a practical example of humanely understanding the customer psyche. Similarly, when I joined the Bata Shoe Company in 1969 as a management trainee, the first training we were given was to work in the retail shops for one week, irrespective of whether we are going to end up in marketing, purchasing, finance, technical or quality control. I still possess the leaflet we were given on the first day we joined the company, the contents of which goes as follows:

WHO IS A CUSTOMER

• A customer is the most important person ever in our business…in person or by mail.

• Customers are not an interruption to our work…they are the purpose of it.

• We are not doing them a favour by serving them…they are doing us a favour by giving us an opportunity to serve them.

• Customers are not dependent on us…we are dependent on them.

• A customer is not an outsider to our business…but a part of it.

• Customers are not cold statistics…they are flesh and blood human beings with feelings and emotions like our own, and with biases and prejudices. 

• A customer is not someone to argue…and match wits with. Nobody ever won an argument with a customer.

• Customers are people who bring us their wants. It is our job to handle them profitably, to them and to ourselves.

Honestly, I should say that as a freshly joined management trainee in 1969, it took me many years to realise the implications of these time-honoured pearls of wisdom about interpersonal relationships. With the proliferation of online sales and e-marketing, the customer has become an obscure or virtual figure or a non-entity. Going to the bank and exchanging greetings with the counter clerk or having a friendly chat with the vegetable or fruit vendor down the street is a thing of the past and a luxury which only a few retired persons like me can afford to enjoy.

Voluminous studies and research have been done in the past from the time the human relations approach to management which started about 100 years ago. It is still an area that the modern day management thinkers, CEOs and specialists of the many disciplines related to human behaviour are grappling with. New theories and hypotheses are continually emerging. The modern managers are very often overwhelmed by the challenge of discerning the trees from the forest, and I am aware about two companies in my own country that were duped by ‘marketing experts’ – to spend millions on magnanimous customer relations programmes which proved to be failures.

Customer satisfaction is a requirement of performance evaluation under Clause 9.0 of ISO 9001:2015. Some companies have developed rather intricate quantitative methods to evaluate customer satisfaction. Poor response rates are a common trend unless the products or the services are of a high level of importance and the consequences of failures are catastrophic. The cost of not fully comprehending what the customers want can be high and the consequences can sometimes be disastrous.

The behaviour and body language – the genuine vs the artificial smile – can be easily spotted. It could be the glittering front office of a large multinational company or an airline check-in counter or the flight cabin itself. Or it may be a small kiosk or a boutique in a remote village. The underlying principles are the same. The courteous, patient and the enduring etiquette of the saree vendors in many parts of India and the remarkable business success of some minor communities in Sri Lanka provide good examples of staying close to the customers.

Customer satisfaction is the extent to which we strive to meet the needs of the customers. However, the way the modern market promotion and advertising is continuously striving to create new needs and wants with only the financial bottom-line as the supreme priority makes me wonder if we have a ‘hen and the egg’ situation in modern business. It was Mahatma Gandhi who once said, “The world has enough for everyone's need, but not enough for everyone's greed.”

According to a recent market study, some common pitfalls of poor customer experience are enumerated as:

a) Rushing it

b) Losing focus

c) Assuming satisfaction, loyalty, advocacy is the same

d) Letting the stakeholders to influence the customers

e) Making rash decisions

f) Comparing apples to oranges

g) Keeping it as a secret

h) Ignoring the data

i) Thinking short term

j) Standing still

Some important aspects to be considered in understanding the customer behaviour have been identified as follows:

• Marketing positioning and distribution

• Personal factors such as age, gender, education and upbringing

• Psychological factors such as buying motives, perceptions and attitudes

• Situational factors such as physical surroundings, social surroundings and time factor

• Social factors such as social status, reference groups, social media and family

• Cultural factors such as religion and ethnicity

• Lifestyle factors such as status, income and identity

• Geographical factors such as the country, religion, urban or rural

With all due respect to the modern approaches to understanding the customers, I find it opportune to cite a far-reaching teaching from the Buddhist doctrine which has deeper management implications on interpersonal relationships. Once the Buddha noticed a young person called Sigala, from an affluent Brahmin family, worshiping reverently at different directions after having his ritualistic bath at the Ganges. It was found that he was following the death wish of his late father. The Buddha explained to him the real significance of the six directions of worship, which is a lesson for the modern managers on harmonious interpersonal relationships. The discourse covers in great detail the duties and responsibilities of the different stakeholders of the social fabric, namely:

• Parents-children

• Students-teachers

• Husband-wife

• Friends and associates

• Employer-employee

• Individual-religious fraternity

It can be seen how these interactive factors cover every aspect of our lives on a life course approach, irrespective of geographical, national, social and religious boundaries, in a world made complicated by our own ambitions and actions.

The past few years have not been easy for Indian industries. From post-pandemic recovery and supply chain issues to trade policy shifts and geopolitical conflicts, businesses across sectors have been navigating uncertainty. Yet, amidst this turbulence, the Indian tyre industry is emerging resilient – steadily carving out a global presence and positioning itself as a poster boy of India’s manufacturing story.

In the last one month alone, three developments have highlighted the strength, adaptability and future-readiness of the Indian tyre sector. Together, they offer a glimpse into an industry not only responding to challenges but also reimagining the road ahead.

Despite rising protectionism and the lingering aftershocks of disrupted global supply chains, Indian tyre exports have continued their upward march. In the last fiscal year, tyre exports from India have grown by nine percent year-on-year – a clear indication of global confidence in Indian-manufactured tyres. Tyre exports from India reached INR 250.51 billion compared to INR 230.73 billion in the previous fiscal, as per data released by the Ministry of Commerce, Government of India.

This isn’t just a story of volume. It’s a story of credibility – built on strong domestic manufacturing capability, world-class quality standards and a heightened focus on research and development.

Today, Indian manufactured tyres are competing with the best on parameters of performance, durability and cost-efficiency and providing a value proposition difficult to match. Indian tyres are exported to over 170 countries, with significant presence in the United States, European Union, Latin America and Southeast Asia. The US remains the top export destination, accounting for 17 percent of India’s tyre exports by value, followed by Germany (six percent), Brazil (five percent), UAE (four percent) and France (four percent).

With an estimated annual turnover of INR 1 trillion and exports exceeding INR 250 billion, the Indian tyre industry stands out as one of the few manufacturing sectors in the country with a high export-to-turnover ratio.

This export momentum has been further facilitated by the government’s active support in promoting domestic manufacturing through Make in India and other export-enabling reforms.

Perhaps nothing captures the maturing of the Indian tyre industry better than the recent global rankings by Brand Finance, the world’s leading brand valuation consultancy, which features four Indian tyre manufacturers – MRF, Apollo, CEAT and JK Tyre – among the world’s 15 strongest tyre brands. In fact, MRF, with a Brand Strength Index (BSI) score of 83.5, ranks as the third strongest tyre brand in the world after Michelin and Goodyear, according to the Brand Finance report.

This is not mere symbolism. It reflects decades of effort in building product trust, expanding global footprints and investing in brand equity. From high-performance radial tyres to off-the-road solutions, these companies are not just making tyres – they are shaping mobility experiences across geographies.

If the present is promising, the future looks even more exciting. A Vision 2047 report by PwC forecasts a CAGR of 11–12 percent for the Indian tyre industry over the next two decades. That is not just encouraging – it’s transformative.

This projected growth rides on several powerful drivers including rising demand from rural and semi-urban India, rapid growth in two-wheeler and commercial vehicle segments, a paradigm shift towards electric mobility and smart transport, greater OEM activity within India as global players deepen their localisation strategies and government policy support that encourages domestic production and discourages non-essential imports.

It’s also a growth that aligns with national priorities – self-reliance, sustainability and job creation.

India’s tyre industry is no longer playing catch-up. It is setting benchmarks. It is innovating, expanding and winning trust in markets around the world. It is making bold bets on sustainability, supply chain resilience and digital transformation. Tyre manufacturers in India have collectively invested nearly INR 270 billion over the last 3-4 years. These investments, spanning both greenfield and brownfield projects, highlight the industry’s confidence in India’s long-term growth potential and the industry’s commitment to capacity expansion and technological advancements.

As we steer towards 2047 – India’s centenary of independence – the tyre sector stands ready to play a pivotal role in the journey. One that connects not just places but aspirations.

Rajiv Budhraja is Director General of the New Delhi-based tyre industry association, Automotive Tyre Manufacturers’ Association (ATMA).The views expressed here are personal.

OTR tyres, rugged design and advanced technology that withstand the most demanding conditions... From mining to construction, these giant tyres play a critical role in keeping industries running smoothly.

What does the term ‘off-road tyre’ mean to us? Giant, robust, special and imposing – a tyre for heavy-duty vehicles. While there are already some tracked loaders and cranes on the market, stationary work, excavation, loading and transport are carried out with mobile machinery in open-pit mines or on heavy-duty construction sites. Transport vehicles, cranes and large-capacity loaders are always equipped with robust and durable rubber tyres. The last 50 years have seen a true revolution in the off-road tyre segment, as tyres have become larger every decade. Newer dump trucks have higher load capacities, requiring the installation of larger tyres to meet this growing demand.

Today 3,500-plus hp engine big haulers loaded carriage capacity reaches to 400-plus tonnes equipped with a tyre such as 59/80R63 extra load size. Such trucks are coupled with loaders having a shovel capacity of 60 tonnes on open pit areas. These load capacities are enormous, and the new generation of trucks offers even more. Tyre sizes up to 63/80R63 or some other size combination with low platform and wider dimensions are in the market.

Thirty to 40 years ago, tyre sizes for 50-80-tonne haulers were around 36.00-51 or smaller. Today, we are talking truck carriage capacities of 450-500 tonnes with hybrid engines. More efficient AC electrical drive haulers and having tyre sizes up to 70-inch rim size tyre are on the pipeline. These vehicles will be able to accommodate tyres with a diameter of over four metres, a weight of over 5.5 tonnes and a load capacity of over 120 tonnes per tyre.

High-tensile reinforcement materials and new generation rubber compound technologies play an important role in these revolutionary developments.

Extreme conditions, extreme performance, heat and puncture resistance for uninterrupted operation... This is how OTR tyres master harsh environments (quarries, mines, construction sites).

Tyres for open-pit mining, underground mining and construction remain separate categories. Their dimensions and basic requirements also vary. However, load capacities and the number of autonomous structures with electric motors and ultra-wide tyres are steadily increasing. The use of advanced materials in self-monitoring tyres with integrated pressure and wear sensors will become more widespread. Giant radial tyres for electric vehicles will proliferate on the market.

Tyre demands for extreme load-bearing capacity, improved cut and tear resistance (against sharp, abrasive stones) and improved heat dissipation through deep tread patterns will increasingly prevail, in line with customer demands. While the tread depth of off-road tyres was only 50 to 60 mm in the 1970s, today’s deep-tread off-road tyres reach 100 to 110 mm. Radial construction with new compound and heat dissipation technologies enables off-road tyres with deeper tread patterns, which also represents a significant advantage for the circular economy. Low-temperature off-road tyres also offer higher and multiple retreadability.

Both bias-ply and radial off-road tyres face significant challenges such as heat, abrasion, traction, sidewall cuts and fire protection. Although current off-road tyre technology has advanced significantly compared to earlier radial off-road tyres, some brands use bias-ply reinforcement layers, primarily on the sidewalls or tread, for improved cut resistance. Bias-ply off-road tyres remain preferred for certain applications, particularly forestry and some mining tyres.

Titan International (USA) underscores its strong presence in the truck tyre market with its Mining & Construction Bias division. This underscores the strategic priority of these specific applications in the OTR   tyre market. In the US, Titan focuses on cut-resistant compounds and special tread patterns for rock environments that perfectly meet the most stringent performance requirements of bias construction.

Michelin, Bridgestone and Goodyear dominate the OTR tyre market, with demand varying regionally. Large tyres for mining, underground mining and construction require durability, heat resistance and smart technology to meet the changing needs of the industry.

Michelin, Bridgestone and Goodyear dominate the global OTR tyre market, but Continental and BKT are also important players. Titan, Yokohama, the Chinese company ZC Rubber and the Indian company Apollo are other niche players that could disrupt global markets with more affordable alternatives. Furthermore, regional demand varies considerably between Asia, North America and Europe due to different mining, construction and regulatory environments. This benefits the different brands, whose combined commercial and technological strengths differ.

Michelin, Bridgestone and Titan (North America and Australia) produce giant mining tyres up to 63 inches wide. BKT, Apollo and ZC Rubber produce low-cost mining tyres in Africa, Latin America and India. Michelin and Bridgestone generally offer smart, autonomous tyres in North America and Europe. Yokohama and Continental (Japan and Scandinavia) offer underground and speciality tyres.

For open-pit mining, powerful electric-powered dump trucks and wheel loaders will offer exceptional load-bearing capacity (over 100 tonnes per tyre). They feature cut and chip resistance (against sharp, abrasive rocks), heat dissipation and a deep tread pattern, which will become increasingly popular.

Underground mining vehicles with narrow low-profile tyres and dump trucks (LHD), on the other hand, will be equipped with compact, fire-resistant low-profile tyres. Their low flammability, puncture resistance and high manoeuvrability will also be important criteria.

Large Scale Construction vehicles like massive dozers, graders, dumpers, articulated dump trucks and motor graders will need high traction tyres for both mud and loose surfaces with reinforced sidewalls to avoid cuts and having high longevity (mixed on road/off road use).

OTR tyre manufacturers compete on durability, profitability and performance. Their primary challenges are extending tyre life, optimising fuel efficiency and reducing wear.

All of the major OTR tyre manufactures need to compete in this high demanding segment of the tyre industry. The biggest challenge in every segment is achieving a long service life without tyre failure. Improved traction and rolling resistance, as well as reduced maintenance requirements, are real advantages.

The cost of a set of tyres is always divided by the total number of labour hours to determine the unit cost per tyre hour. Various parameters influence tyre and other operating costs. To minimise fuel and tyre costs in mines, better road maintenance, operator training in environmentally friendly driving (acceleration/braking), monitoring tyre pressure and loading and the use of predictive analytics (telematics to measure fuel consumption and tyre wear) are essential.

Overloading increases tyre stress, accelerating wear and fuel consumption. Poor road conditions with potholes and spills lead to more cuts and flat tyres, increased rolling resistance and higher fuel consumption. Harsh acceleration or braking always leads to overheating and faster wear. Although large radial-body trucks cost nearly USD 100,000, every preventative measure and maintenance is essential for business reasons.

Innovations such as RFID, flame-retardant compounds and environmentally friendly materials are driving the industry forward. OTR tyre manufacturers compete with specialised designs: mining tyres must be cut-resistant, earthmoving equipment must be durable and port tyres focus on efficiency.

Tyre manufacturers must survive in this highly competitive and demanding industry. Mining tyres are exposed to extreme conditions and require cut resistance thanks to highly abrasion-resistant compounds and additional steel belt layers. Earthmoving tyres require flexibility and durability thanks to all-season tread compounds and rock-resistant designs. Port logistics tyres feature low rolling resistance and chemical resistance thanks to lightweight steel belts. RFID tracking offers real advantages for tyre tracking.

Innovations for niche applications are also essential for brand building and address specific challenges. Some underground mining tyres feature non-marking and flame-retardant compounds for enhanced safety and performance. Arctic tyres require low-glass transition temperature polymers and microspike technology for better traction in extreme cold. As always, off-road electric tyres require improved efficiency and lower noise levels.

The use of recycled materials poses a real challenge for this segment, but more durable designs certainly reduce waste and replacement frequency. However, bio-based compounds and recycled rubber must be more widely integrated into new products.

Key trends in the OTR tyre segment include intelligent monitoring systems, environmentally friendly compounds and improved reinforcement techniques. Graphene-reinforced tyres promise extremely high strength and heat resistance. Sustainability will be a priority in OTR tyre manufacturing, with a focus on reducing environmental impact through innovative materials and designs.

Imagine a giant tyre that weighs twice the weight of your EV, costing as much or more than your EV; you are looking at the largest truck tyres in production. Weighing over 3.5 tonnes and standing better than four metres in diameter, these giants are actually very sensitive.

Such tyres support loads of 100,000 kg; yes, that’s a single tyre. The truck fully loaded is more than 600 tonnes. To put that in perspective, that single tyre supports 50 average cars – that’s 300 cars in a single vehicle.

These tyres have to be managed very carefully to extract the maximum amount of work without destroying them. Overwork the tyres or engage in poor maintenance and the tyre can fail, sometimes catastrophically, and this can happen inside just a few hours of operation.

The OTR (off the road) tyre sector is at the cutting edge of tyre technology. It is paired with the other end of the spectrum being MotoGP tyres, which, whilst a light construction, are exposed to all sorts of side forces as the bikes achieve lean angles of 65 degrees. Both are cutting edge in tyre development.

OTR tyres can have up to 40 different rubber compounds that are required to work in harmony, which is one of the pinnacles of rubber manufacturing. There is deep engineering involved in having different rubber compounds within the one tread package. This happens for select MotoGP circuits where corners one way well outnumbers corners heading in the opposite direction. Your humble daily drive tyre is the result of all the testing and development that occurs within conception of these giant OTR and MotoGP tyres.

The tyre talk within the F1 paddock about tyres is old school for OTR tyres. For many years, a mining circuit was carefully monitored after the theoretical calculations had been made as to how far and fast could these giant haul trucks travel. The reasoning behind these parameters was based around the tread and compound selection. This is known as the tonne kilometre per hour factor. Some operations required a high-speed compound, which was usually less abrasion resistant but have a higher heat capacity. Whilst slower speed operations wore cut-resistant tread packages. Low-speed operations such as underground receive yet different tread patterns and compounds. Then there is the appropriate tread pattern and class to select.

In periods of high demand, there have been many attempts to produce OTR tyres, quite often with limited success. I observed one truck that had been fitted with an emerging manufacturer’s tyres that didn’t even get to the loading point before the whole tread package separated from the carcass. These giant tyres are fragile and sensitive.

Applying appropriate maintenance has been made proactive with the advent of real-time TPMS. Decisions on the vehicle’s duty cycle can be made depending on what level of work the tyre pressures indicate they are experiencing. Just like MotoGP and F1, the tyres are the limiting factor of performance. Even suspension issues can be identified as the load centre shifts towards the weak suspension component.

Unlike on road tyres that have a large safety margin designed into them, OTR tyres are often worked to their maximum, and in early days of mining, well overloaded and over run. When the OTR tyre supply went into shortage, many OTR tyre users realised that without appropriate management, the sustainability of their operation

would be called into question. Tyre costs can easily blow out and cause a lot of economic angst and pain.

Truck and fleet managers who are at the top of their game utilise real time tracking of the vehicles to identify their capacity for work, that is how far and how fast can the truck travel before the tyres become overheated. With a combination of GPS tracking and tyre pressure monitoring, tyres can be observed and the truck reallocated to a shorter lighter haul before the tyre sustains heat damage. A tyre is very much like a loaf bread or a cake; you can overcook it, and alas, the outcomes are not reversible. Once the cake is burnt, it’s ruined; an OTR tyre is no different.

With such an expensive asset, organisations have realised that without tyres, their operations come to a grinding halt. In TyreSafe Australia terms, “if they are not turning, they are not earning” has never been more factual than during an OTR tyre shortage. Executives have come to understand that tyres for a rubber-tyred haulage operation represent a very large cost centre, quite often in the top three or four expenses. There are many aspects to extracting the best performance from these gentle giants, but most importantly, it is the provision of the appropriate volume of inflation medium.

By engaging a tyre data management platform, such performance data and detail can be gleaned and used to programme maintenance and also to provide feedback for the production crews, who ultimately should be the ones paying for the tyre operational costs. A fresh mining area under development may well result in an increased number of cut and damaged tyres. The tyre crews see this on a daily basis as they attend their charges, but the old head in the sand attitude of ‘move more tonnes’ touted by some miners usually ends up being an economic disaster. Having observed operations driven by production tonnages, I have also been witness to the absolute waste of tyres that have been cut and damaged by poor operational practices. Such operations do not usually make a profit.

A tyre manufacturer can produce a superb product that has the potential to achieve best practice life, but if an end user drives over a rock that fatally injures the tyre, how is this reconciled? The tyre manufacturer has no control over what the end user does – the same as your daily drive where tyres are left unattended until there is a failure. Then it is the tyre’s fault, NOT!

The technology involved in being able to manufacture a rubber item with upwards of 36 different rubber compounds within the single tyre is enormous. Each different rubber has different properties the designer is seeking to utilise. Having these compounds adhere to the adjoining rubbers is a scientific mine field; it can work, but it can also come apart quickly.

Using software to design tyres both in constructional terms as well as the actual operational side of the tyre has meant that advances can be made within days rather than months or years. Having been part of a tyre development team, I had to wait for the new design tyres to be designed, then manufactured and shipped to site before being mounted. Only then can they go into operations where the research from the technical design team was proven. The software used today can now simulate the operations and identify any weaknesses in the tyre design even before the physical production mould is created. With CAD/CAM machines, now fine sipes within the tread pattern can be included. John F Sipe must be amazed to see the intricate patterns now being produced. The sipes not only provide better traction for on road tyres but permit a shorter heat path for OTR tyres.

When the tyre is operating, the resultant hysteresis is evidenced by the level of temperature rise within the tread and casing. The interface at the casing tread is the most sensitive and most easily damaged by overwork or overspeed, or under pressure. Excess heat is the mortal enemy of an OTR tyre.

With appropriate management of operational factors, an OTR tyre can be capable of many thousands of hours’ work. With bad management, the tyre may well die within just several hours.

By managing tyre inflation pressures, a sound reflection of the operation’s philosophy towards creating profit can be determined. The easiest way to ensure your tyres perform as the OEM designed is to monitor and maintain the inflation pressure. It’s not that hard, surely?

Take care, stay TyreSafe.

Raw materials and sustainability are symptomatic of a tyre when you think about it.

As a society very dependent upon mobility, our drivers and passengers need to be able to enjoy sustainable service from the tyres our industry produces. To date, primarily raw materials have been used in manufacturing, but there is a paradigm shift underway. The recyclability of tyres is as yet still a question more than a solution, from an economic perspective as well as an environmental approach.

As we are all observing, global economics is entering an interesting phase and hands are being outstretched looking for payment or retribution, or both.

The tiresome question in front of everyone is ‘what is the cost’?

a) Of not doing ‘it’

b) Of attempting to do ‘it’

c) Of being able to enjoy economic success to do ‘it’

d) Having positive outcomes for the environment or at least neutral

e) Option C as well as D, very hard to achieve this balance in my opinion, but nevertheless, is the most desired

The ‘it’ in this case is producing a tyre with no adverse effects or outcomes.

Tyre OEMs are progressing through the issue of designing tyre tread patterns as well as structural casing considerations (even down to acoustic considerations from inside the tyre’s air chamber) as the tyre in motion is now the largest noise generator (no engine or exhaust noise) on a current generation electric vehicle (EV). Having high levels of noise is part of modern life; however, as people, we don’t accept noise intrusion, especially inside the modern auto cocoon, sorry, car. How far do we push sustainability?

A tyre admirably demonstrates there can be reciprocity and sustainability between unlikely companions. Nominally, inflexible steel lives happily with totally flexible rubber whilst the road pavement (bound stone, cement or unsealed) abrades the tread rubber. From an unsustainable perspective, there are the tread road wear particulates (TRWP) that are generated at the tread pavement interface; huge questions here as the yet to be determined answers need to be found.

With more fuel-efficient propulsion systems, greater demands are placed on the humble tyre. Rolling resistance (of the tyre) is a major consumer of energy and now, not forgetting, aerodynamics too.

The global program of ‘safer vehicles’ also has impact on tyre performance not only on the overall life but also the traction / grip aspects. Vehicles that are heavier, faster and more responsive place increased demands on tyre performance.

WANTED: lighter, quieter, more grip in all conditions, longer life, greener, cheaper ... the holy grail.

There is a price to pay; as Isaac Newton stated, ‘to every action, there is always opposite and equal reaction’. This is a basic law of physics, the third law of motion. There is no free lunch; we usually pay in many ways, either in the short term, the medium or the long term, or in all terms.

Retreading is very much a partial solution using the casing of the tyre to yield second, third and more lives. Tyre OEMs have not favoured retreading in past times as for every tyre retreaded, a new virgin tyre was not required. Tyre manufacturing facilities operate on volume; the more they can produce, the lower the cost of each item. Selling more tyres was the only answer. Retreading has many benefits, and with modern electronics, the quality of the product can be as assured as a virgin tyre. In some cases, the performance of the retread can be superior to that of the original tyre. Retreading is a sustainable practise to a point. Eventually, the tyre’s structural casing will fatigue and fail. Commercial aviation tyres are retreaded numerous times as a matter of practise. An aircraft tyre will experience loads well in excess of that your daily drive tyre experiences. When the tread is worn down, it is replaced with a new tread package. The other very important consideration in regards tyre retreading is the reduction in the consumption of raw materials. A tyre is assembled using upwards of 40 percent carbon black. There is about 20 percent steel and fibre product whilst the rubber that converts to a petroleum oil during the pyrolysis process is the remainder. Every casing reused reduces the requirement for fresh raw materials and associated manufacturing.

Whilst recycling offers sustainability in a circular economy scheme, there is a long way to go before sustainability is actually sustainable. With increased recycling and the rise of the circular economy, past attitudes are being revised, modified, changed or rewritten. The prime hurdle to jump for this potentially emerging (recycling) industry is the refining of the end products tyre pyrolysis systems generate. The carbon black has many challenges before re-use for tyres. The oil also requires refining prior to replacing petroleum. What about the byproducts from the refining process? If the pyrolysis product is more expensive than the original raw material, will you as the consumer still buy cheap? If so, why are we, the tyre OEM s, investing in our ESG programme of sustainability?

Repurposing end-of-life tyres has great potential, but there are concerns around the outcomes if such products are used. Ground rubber used in uncaptured soft fall has been outlawed in some jurisdictions; even captured rubber such as in hot mix bitumen has outfalls (TRWP). Geological uses as ground support and river stream bank erosion mitigation are another limited use. The re-use of the raw materials is the ideal outcome, but sustainability is still a process in progress.

All processes are required to extract the highest outcomes from our raw materials as well now (with landfill diminishing capacity), thinking about end-of-life products (not just tyres, think about electronics, for instance, and the list grows), so there is a requirement to promote the recycling, re-purposing and retreading of tyres. The retreading facilities can be localised geographically to reduce the sea transport for virgin tyres from manufacturing facilities to the end destination. Pyrolysis and re-purposing facilities are best locally located, but there has to be a market for the downstream products; this is a crunch point. However, there are advantages that we are currently not availing ourselves of with the many economic benefits seemingly available. With export/import tariffs introduced or even if sea lanes are unable to be used to import/export tyres, then retreading capacity will be a license to print. There must be a strategic deliberation to include tyre retreading in national planning as well. Our mobile society requires tyres; from farm to plate, our food is supported by tyres for much of the journey, then there is the rest of life.

We should not underestimate the critical role tyres play in our global supply chains and mobility; however, the price we pay has to be sustainable in the long term. That means easing our demands on raw materials including the use of recycled products, but we also need to extract better performance not just from the tyres so much but also from the maintenance of the vehicles. In my overviewing large data sets of tyre life performance, it has been noted that ‘we’ use only about 65 to 70 percent of the available tread; many tyres are scrapped earlier than they should be as a result of irregular wear and/or poor maintenance. Considering the aids available today (namely drive over alignment pads, tyre pressure monitoring systems TPMS), there is little excuse for such dubious maintenance decisions stemming from sub-standard economic directions.

The old model of ‘produce more sell more’ has a large price to pay. Sustainability is now becoming a serious issue in our supply chains. We (businesses) have to be able to open the shop doors tomorrow, and that means generating capital reserves that enable us to pay the bills and put food on the table.

What price is sustainability? Are you prepared to pay today for tomorrow’s sake?
