Please forgive my indulgence on the topic of tyre testing, but the end result of a safe tyre is, the tyre is only safe IF the appropriate inflation pressure is used!

The physical road testing of a pneumatic tyre is the last part in a very long line of testing procedures used to manufacture the tyre. The actual manufacturing is not the end of the line as the tyre has to be competently mounted to a wheel and then appropriately inflated prior and during use.

If the tyre/wheel assembly is not balanced in mass and dimension, then the tyre is not going to perform as expected, nor will the tyre perform as expected if the inflation pressure is not appropriate to the load and speed the vehicle is going to be utilised at.

The humble pneumatic tyre is a composite assembly of many different materials, each having to work in harmony and unison with each other.

The different materials used to manufacture the tyre have already undergone substantial testing as individual products to assure the sought-after properties and qualities are exactly what is required to produce a tyre that is not only safe but performs as expected.

Many years ago, on a major construction project in Asia with one of my clients, the tyre company I was an engineer with suffered many catastrophic tread separation failures. This was a time critical project so having haul trucks out of service was a serious impediment to achieving the extensive earthworks required. A long story short, I was given to understand that there was a change in the supplier of the carbon black used in this particular tyre tread specification. The fresh manufacturer’s product checked all of the (then) testing parameters, but when it came to actual live service, there was a deficiency somewhere. I was never privy to the actual product details, just the end result of seeing haul trucks with fuel and hydraulic tanks on the ground having been slapped off by tread packages parting from the tyre casing. Having up to 1,000 kg of tread rubber flapping out of control is not conducive to a safe operation.

The testing regime for the product used was seemingly insufficient to identify this issue pre-production, ending up with very costly results.

One can read in various publications of tyre testing where a group of journalists and motoring writers take vehicles fitted with various tyre producers’ products around a circuit in an attempt to quantify the performance, in lap times, but more importantly, in feel.  ‘Through the seat of your pants’ is a commonly used phrase.  As a young two-wheel motorcycle racer, I progressed from using treaded road tyres to a full racing slick. The feeling was totally different and, to be honest, I didn’t ever get the slick tread tyres to operate as they were designed.  After progressing to three-wheel bikes (sidecars), slicks became the ideal product.

In todays’ tyre production world, I suggest that the development on MotoGP motorcycles leads the way. Think of a MotoGP bike where cornering lean angles of up to 65 degrees, yes 65 degrees, are common place, all the time transmitting a power to weight ratio of more than 1:1, which is more than one horsepower per kilogramme of weight (including the rider!).  When combined with the technology developed in the giant OTR tyres used in mining, the development of tyre performance is progressing rapidly. The ability of a giant mining tyre to support a load in excess of 100 tonnes per tyre (think 50 average passenger cars, yes that’s per tyre) whilst travelling at 60 km/hr is an everyday event for a mining operation. These tyres on a drive position transmit thousands of horsepower to motivate the truck. These numbers are far in excess compared to your daily drive!

A passenger car tyre benefits greatly from all of this research and development leading to the actual physical testing of the tyre in the hands of the journalists pushing a car around a circuit.

Yet, all this testing can be undone by the end user’s reluctance to verify that the tyre’s operating pressure is appropriate for the duty cycle being undertaken. The adoption of real time tyre pressure monitoring (TPMS) has generated an increase in safety IF the driver actually uses the data.

Race pilots (drivers and riders) carefully study the operating tyre pressure detail as they well understand that just ½ a psi may make the difference between winning or finishing off the podium.

Alas, our industry has not really educated the daily driver to the critical importance of ensuring their tyres have the appropriate inflation pressures installed. Inflation, it seems, is only important to economists and price rises.

All the material testing, quality control in production and physical mounting of the tyre can be undone by the ignorance of the end user in not attending to the inflation pressures adequately. No matter how deep the science used, the quality control measures employed within production our product’s success remains at the whim of the end user as to whether they can be bothered to ensure the very item that provides their safe passage is indeed fit for purpose.

Regardless of the impressive advances in testing technology, the serious quantitative leaps in the use of computer aided design and manufacture, the improvements in material science yielding growth in all the useful features for a tyre combined in production benefitting the end result can be undone by end user apathy. As an industry, we have a programme of continuous improvement, but does the end user have the same? Do they care?

For all the testing programmes we, as an industry, have in place, the one lacking I feel is the understanding of the level of knowledge from the perspective of the driver. Do they understand the information that the physical tyre testing provides? In the case of a motoring enthusiast, very much yes, but they make up a small percentage of the population.

The advent of the Euro 7 standards will draw the performance of tyres into the everyday realm for the legislators and regulators. Again, how the daily drivers that use their vehicles for commuting actually care is an unknown, and I feel that the care factor is probably less than zero.

In speaking with learner drivers, I ask whether the driving instructors had mentioned tyres at all and was totally unsurprised when the answer came back as a no. I know I have said before that unless we can engage drivers into understanding and appreciating their tyres’ contribution to their personal safety whilst driving, then our industries progress will be stymied.

All the progress in material science, advanced vehicle standards, wonderful testing regimes can all be negated when the vehicle driver ignores the very basic of the tyres operating requirement – the appropriate operating inflation pressure. 

How we change the mindset of the end user is still testing my knowledge and patience; it is more than tiring to keep on hearing that people don’t even acknowledge the benefits they enjoy from the use of the product our industry produces.

Please educate the end user on the critical importance their tyres have in overall on-road safety. Look after your tyres, so when you call upon them to look after you, they will be appropriately equipped to do so.

The Indian automotive landscape is currently undergoing a seismic shift. Driven by the rapid rise of rural urbanisation, an aggressive government push for electrification and the development of world-class road infrastructure, the industry is witnessing a period of robust growth. With sales of both new and used vehicles touching record highs, the demand for high-quality tyres remains in a significant upswing.

At the helm of one of the market’s most prominent players is Rajarshi Moitra, Managing Director of Bridgestone India and Vice-Chairman, Automotive Tyre Manufacturers’ Association (ATMA).

In an interaction with Tyre Trends, Moitra discusses the company’s future-ready roadmap, from its substantial capacity expansions to a ‘sharp and deep’ strategic focus designed to maintain leadership in an increasingly premium and electrified market.

A BULLISH OUTLOOK ON THE SUBCONTINENT

While global economic indicators remain varied, Moitra is unequivocally optimistic about the local trajectory. “The Indian automotive industry is at an exceptionally positive juncture from a medium-to-long-term perspective,” he asserts.

This optimism is grounded in several structural tailwinds that suggest India is slated for very strong growth. Key among these factors is the sheer room for market expansion.

“Firstly, we are still significantly under-indexed in terms of car penetration, with only 50 cars per 1,000 people – well below even some smaller developing nations,” Moitra explains.

Furthermore, the geographical spread of wealth is changing. Bridgestone is observing massive growth in Tier 2, 3 and 4 towns, a phenomenon Moitra attributes to ‘rural urbanisation’.

Bridgestone India estimates a transformative half-decade ahead for the industry. “The number of affordable households – those capable of purchasing a car – will double in India over the next five year. When you couple this with the government’s massive capital outflow into road connectivity and the rise of e-commerce, it creates a very bullish environment for both passenger and commercial mobility,” Moitra says.

THE ‘SHARP AND DEEP’ STRATEGIC PILLAR

Despite India being the world’s largest two-wheeler market, Bridgestone is famously absent from that segment – and intends to stay that way for now. Moitra clarifies that the company’s philosophy is rooted in specialisation rather than horizontal expansion. “At Bridgestone, we believe in being ‘sharp and deep’ in our strategy,” he says.

Currently, Bridgestone India’s business split is heavily weighted towards the consumer segment, with 70 percent of sales coming from Passenger Car Radial (PCR), 25 percent from Truck and Bus Radial (TBR) and 5 percent from Off-the-Road (OTR) segment.

“We see enough headroom for growth within the passenger car segment across products, channels and customer experience, so we are focusing our resources on maintaining our leadership there,” Moitra notes, dismissing any near-term plans to enter the two-wheeler space.

Instead, the company is doubling down on ‘white spaces’ within the consumer car category, specifically targeting higher rim diameters and specialised compounds for Original Equipment Manufacturers (OEMs).

INVESTING IN CAPACITY AND LOCAL INTELLIGENCE

To support this growth, Bridgestone is moving aggressively on the manufacturing front. With current operations running at 90–95 percent capacity, the company is in the midst of a major investment cycle.

At present, the company’s Pune plant has a capacity to produce 4.01 million passenger car tyres and around 693,000 truck & bus radial tyres, while the Indore plant has a capacity to produce 7.11 million radial tyres for passenger cars and light trucks.

“Our last major investment was USD 85 million in October 2024, which is being ramped up in phases through 2029,” Moitra confirms. This capital is being used to scale volumes and enhance technical capabilities at the Indore factory.

The new investment is expected to further add 1.1 million tyre production capacity in Pune by CY2029, thus taking its total production capacity to around 11.1 million units in the country.

“Our strategy is two-fold: we want to be future-ready for market demand while simultaneously sweating our current assets to drive higher efficiency,” Moitra explains. Crucially, this expansion isn’t just about physical output; it’s about local autonomy. Moitra highlights that a ‘very large part’ of procurement is now local, decided by teams on the ground in India.

The launch of a Satellite Technology Centre in 2025 has further decentralised the company’s innovation engine. According to Moitra, this centre plays a pivotal role in increasing local leverage and technical presence, allowing the Indian arm to maintain a balance between local agility and global sourcing.

EVs AND PREMIUMISATION

As the Indian market matures, consumers are demanding larger wheel sizes – a trend Moitra says is led by OEMs. “We are seeing a clear market shift towards higher inches – for example, a car like the Maruti Suzuki Swift moving from 14-inch to 15-inch and others moving from 16-inch to 17-inch,” he observes.

Bridgestone’s ‘all-inch’ strategy covers the spectrum from 12 to 20 inches, but their brand strength is most potent in these premium, higher-diameter sizes.

This premiumisation dovetails with the transition to electric vehicles (EVs). Bridgestone has positioned itself with an ‘EV-ready’ portfolio, exemplified by the Turanza 6i. “It balances long-lasting durability and safety with low noise and comfort – essential for EVs,” says Moitra. To ensure they capture this nascent but fast-growing market, the company expanded the range from 36 sizes in 2024 to 72 sizes by 2025.

The OEM relationship remains the cornerstone of this technological foresight. “The OEM segment allows us to see ahead of the curve regarding future vehicle technologies,” Moitra explains.

At present, 35 percent of their consumer business is OE-based and Bridgestone is in active discussions with many of the newer automotive entrants arriving in India.

While Bridgestone is aggressively expanding its footprint in new tyre technology and premium consumer segments, it is taking a markedly more conservative approach towards the retreading sector in India. Despite the potential for material circularity, the company does not view retreading as a strategic priority for the immediate future.

Moitra clarifies that Bandag, Bridgestone’s global retreading arm, is not currently active in India, and there are no plans to introduce it in the near-term. This decision is driven largely by the unique and challenging dynamics of the local market, which is currently dominated by cold retreading.

He points out that a significant pricing challenge exists when ‘cold retreads versus biased tyres versus some of the cheaper tyres’ are compared, making the business case difficult to justify at this stage. Consequently, Bridgestone has opted to remain focused on its core segments for the next two to three years rather than entering the retreading space.

SUSTAINABILITY AND THE ‘INSTITUTION OF RESPECT’

Beyond the numbers, Bridgestone is attempting to build what Moitra calls an ‘institution of respect’. This involves a heavy commitment to environmental goals. The Pune plant already holds the distinction of being the first carbon-neutral facility in the Bridgestone group.

“Sustainability is a core agenda across our entire value chain,” Moitra explains, noting a public commitment to reduce the company’s carbon footprint by 50 percent by 2030, including Scope 3 emissions. This holistic approach ranges from manufacturing processes to material circularity in the tyres themselves.

Looking ahead, the goal is to protect a dominant market share – currently over 20 percent by volume and 23 percent by value in the passenger car aftermarket. To do this, Bridgestone plans to expand its physical reach by 30 percent over the next five years, building upon its current network of over 4,000 touchpoints.

As the company transitions its branding from the Olympics to Formula E, the focus remains clear: high performance and the next era of mobility. “It’s the perfect platform to showcase our technological edge,” Moitra concludes.
