TIRED OF POOR TYRE KNOWLEDGE

As I speak with industry members, regulators and legislators I continue to be stunned by the lack of appreciation of the very critical role that tyres play in our societies.

Governments bleat about fuel security “investing” precious currency to prop up petroleum fuel storage and production in the face of the ever-expanding development of electric vehicles and more recently the advent of hydrogen as a viable fuel with thanks to the PV (solar) industry advancements. Tyres? What do you mean tyres? Without tyres our societies would grind to a halt in the near term. How are they not a strategic consideration?

Our industries (tyre, road freight transport, mining, public transport and leisure) are facing sufficient difficulties with COVID as well as international shipping challenges to be faced with continued ignorance and negligence by our legislators and regulators.

Please review your countries legislative requirements in regards tyre inflation for light vehicles (say <4,500 kgs) and then the same requirement for heavy vehicles (>4,500 kgs). What do you find?

Mostly I think you will find that tyre inflation pressures are regulated for light vehicles via the vehicle manufacturers tyre placard. For heavy vehicles there is little, if any, such requirement. To illustrate the yawning gap between reality and regulation one peak heavy transport regulatory body published a procedure for roller brake testing for heavy vehicles. The procedure details in minute detail the requirements of the pneumatic system on the truck under test yet merely stated “tyres should be inflated.” As everyone in the tyre industry understands a tyre can be inflated at low pressures totally unrelated to actual operating pressures. What connects the brakes to the pavement? Tyres!

I’ve spoken at length about the absolute requirement for a tyre to be appropriately inflated. This is basic physics, the air molecules captured within the tyre’s air chamber actually support the applied loads. If there are insufficient molecules of air the tyre will be overworked so overheat and so enter a failure phase. There are other requirements for the inflation being the actual shaping of the tyre to interface with the pavement at the optimum level, read traction. A wide based tyre requires special construction to maintain the tread platform shape. If the inflation pressure is not at the manufacturer’s specified level will this critical shape be maintained? Then it is not only the performance of the tyre in question but also the safety of the vehicle and that of the general public in the areas this vehicle operates in.

The extensive report produced by the TNO Organisation (TNO 2013 R10986) detailed not only the exhaust emissions as a result of inappropriately inflated tyres but also the road safety outcomes. This paper is now just over eight years old but the situation with real time pressure monitoring for heavy vehicles remains as it was, 50 years or more ago. WHY? Are our regulators asleep at the wheel (or tyre some may say) through entrenched inaction and ignorance? Or is it that there are just “no votes” in tyres and everyone just ASSuMes their tyres are “ok”?

EV tyres

With the advent of electric vehicles, the ramifications for tyres are huge. In the past internal combustion engines (ICE) built up torque over a rev range, drivelines multiplied the torque developed and for heavy vehicles there is a sweet spot for torque. The multi speed gearboxes assisted the driver to maintain forward motion within this torque sweet spot. Electric motors apply maximum torque over most of their operating range. From the instant the power is applied by the driver (be that human or robotic) the tyres are under peak stress. Any deficiency within the tyre will be magnified with detrimental results. Such a deficiency may be of a manufacturing nature but this is largely controllable by the manufacturer. What is not currently controllable is the human maintenance factor, the applied inflation pressure.

Tyre manufacturers have for as long as they have been manufacturing tyres been informative about the criticality of appropriate tyre inflation. There are untold charts and pictorials showing how a tyre is influenced by under or over inflation yet our regulators and legislators continue to keep their heads buried deep out of the light. WHY when tyres are such a critical component of our modern-day motor vehicle? I would charge ignorance and negligence on one hand but then on the other suggest that because tyres work as well as they do, are as forgiving (by nature of their fundamental flexible design) our “guiding powers” can focus on other trendy and glamorous aspects such as stability control or autonomous braking. An important question for these people to consider and respond to; “what item on the vehicle transfers the power (and so directly influence these vehicle control systems) from the vehicle to the pavement (be that power tractive or retardation)? Yes of course, the humble tyre.

So, when a government sponsored or publicly funded body involved in road safety ignores tyres (for whatever reason, ignorance or negligence) are they really serving the interests of our communities and societies or are they just -- I should stop there but you know where I’m going!

The technology to monitor tyre pressures in real time is and has now been available for decades. The TREAD Act (USA) mandated tyre pressure monitoring (TPMS) for light vehicles in the USA in the year 2000. This year TPMS gets a key for its birthday, yes well and truly a mature product (some may say adult) and industry yet, our regulators and legislators continue to ignore the humble tyre.

The upsides of maintaining tyres at an appropriate pressure I’ve discussed previously, all positive. The same detail has been published in many papers (such as the TNO paper!) but we as an industry continue to live in the past whilst adopting hi-tech solutions for other aspects of our industries, e.g., GPS tracking, fatigue monitoring, reefer monitoring and control, real time video surveillance of the drivers and the surrounding traffic conditions. Why? To me there is little respect paid to the critical role the tyre provides for us. So many users do not consider how the tyre works for them and why the simplest of tasks will enhance the performance, yes, I speak of inflation maintenance. Without respect the tyre will never be recognised for the contribution it has made and continues to make.

I publicly and openly challenge our tyre manufacturers as a collective to mount an education campaign to enhance the level of respect the general public has about tyres. The TIA (US) and USTMA have local campaigns on behalf of their members but I consider that until the tyre manufacturers as a collective industry actual improve the level of respect for the humble tyre we will be chasing our tails on a race to the bottom. Our tyres deserve better!

What about Michelin, Bridgestone, Goodyear, Continental, BKT, Dunlop, ZC Rubber, Hankook, Pirelli, Toyo, Sumitomo, Yokohama, Kumho, MRF, Apollo, Nokian, JKTyres, Cooper, Titan, Linglong, Triangle et al?

Remember success does not reward a lack of action. (TT)

Continental Unveils ZEvRA Concept Tyre With 43 Percent Recycled Materials

Continental has unveiled a concept tyre developed under the EU-funded ZEvRA project, which is composed of approximately 43 percent recycled materials. The innovation serves as a demonstration of the potential inherent in advanced material approaches while simultaneously underscoring the critical need for a dependable regulatory framework to facilitate the industrial-scale adoption of recycling technologies.

The technical achievement is set against the backdrop of the ZEvRA initiative, an acronym for ‘Zero Emission Electric Vehicles Enabled by Harmonized Circularity’. This two-year EU project, slated to conclude in 2026, is dedicated to enhancing the circular economy for electric vehicles across the entire value chain. As the sole tyre manufacturer participating in the consortium, Continental brings specialised expertise to the collaborative effort.

Addressing the complexities of tyre production, which requires a precise balance of numerous high-performance raw materials to guarantee safety, efficiency and durability, the concept tyre represents a significant milestone. The successful integration of a substantial proportion of recycled content into a safety-critical component, without compromising performance standards, highlights the compatibility of ecological responsibility and product excellence. The tyre has achieved the highest possible rating on the EU rolling resistance label.

The ZEvRA concept tyre incorporates a variety of recycled materials, including tall oil, steel, rubber derived from end-of-life tyres and polyester fibres sourced from recycled PET bottles. Continental employs advanced methodologies such as pyrolysis to extract recovered carbon black from old tyres for repurposing. Since 2023, this material has been utilised in all newly manufactured solid rubber tyres at the Korbach facility. Additionally, the company uses sand residue from foundries in a recycling process to produce an alternative silica variant, effectively keeping materials in circulation and reducing the demand for primary resources.

Continental executives have articulated the strategic importance of this development. Dr Andreas Topp, head of Platform Development and Industrialization for passenger-car tyres, emphasises that while circular materials are key to sustainable mobility, the full impact of technological progress requires reliable and aligned policy frameworks. Jorge Almeida, head of Sustainability for Continental’s Tires group sector, stresses the necessity of establishing innovative recycling technologies on an industrial scale and creating closed material flows. He advocates for a standardised, transparent approach to calculation and reporting, developed through close dialogue between policymakers and stakeholders.

Beyond the recycled content, the concept tyre also features approximately 13 percent renewable raw materials and 25 percent mass-balance-certified materials, bringing the total share of sustainable sources to over 80 percent. Continental is progressively increasing the use of such materials across its portfolio, with the share of purchased renewable and recycled production materials reaching 28 percent in 2025, with a target of at least 40 percent by 2030. Insights from the ZEvRA project will guide the company’s future development of materials and technologies, focusing on industrial availability and scaling manufacturing processes.
