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)

Tire Recycling Foundation Announces Inaugural Circle Of Change Award Winners

Tire Recycling Foundation Announces Inaugural Circle Of Change Award Winners

The Tire Recycling Foundation (TRF) has unveiled the recipients of its inaugural Circle of Change Awards, recognising initiatives that convert end-of-life tyres into sustainable materials with tangible community and environmental benefits. The honours, announced during a luncheon at the recently concluded 10th Tire Recycling Conference in Denver, Colorado, highlight growing momentum in end-use markets for recycled tire products.

North Carolina earned the Circular Economy Trailblazer Award for modernising its scrap tyre programme, including a revised funding framework that stabilises county recycling efforts, curbs illegal dumping and establishes a platform to incorporate tyre-derived materials into public works. The Innovation in End-Use Technology Award went to LHB Engineering and the St. Paul Port Authority for redeveloping a brownfield site in Minnesota, where roughly 30,000 yards of tyre-derived aggregate now support an underground stormwater system protecting the Mississippi River from runoff.

Michigan EGLE and its public, private and academic partners received the Market Development Excellence Award for a multi-sector effort using demonstrations and field data to advance tyre-derived aggregate, rubber-modified asphalt and porous pavements. The Value Chain Collaboration Award was presented to Bolder Industries and Pirelli Tire LLC for a closed-loop system that transforms manufacturing scrap tyres into recovered carbon black for new commercial tyre production, reducing emissions and resource use at scale.

The 2026 winning projects demonstrate that tyre recycling and tyre-derived products are established pillars of sustainability and economic growth, reinforcing the value of active state end-of-life tyre programmes focused on innovative market creation. The TRF Circle of Change Awards programme spans four national categories designed to spotlight leadership in advancing tyre recycling and the circular economy.

Stephanie Mull, Executive Director, Tire Recycling Foundation, said, “Every end-of-life tyre represents an opportunity to transform what would have been considered waste into something that strengthens our communities. This year’s winners are proof that when the industry works together, tyre recycling can simultaneously strengthen infrastructure, drive meaningful environmental progress and support local economies.”

Dick Gust, President, Tire Recycling Foundation, said, “What stands out about the 2026 winners is how embedded tyre recycling has become in real-world decision making. The success of these projects sends a clear signal that when recyclers, engineers, transportation agencies, state and local governments, manufacturers and private industry work together, end-use markets grow. That’s the integrated approach we need to continue building on.”

AZuR Network Validated As BCG Study Projects Doubling Of Circular Value Creation In Germany By 2045

AZuR Network Validated As BCG Study Projects Doubling Of Circular Value Creation In Germany By 2045

The Alliance for the Future of Tires (AZuR) is at the centre of a new industrial paradigm, as a recent study by the Boston Consulting Group (BCG) for the Federation of German Industries (BDI) confirms that the circular economy is becoming a decisive competitive factor for Germany. The analysis projects that circular gross value added could more than double from roughly EUR 60 billion (approximately USD 69.60 billion) today to up to EUR 125 billion (approximately USD 144.95 billion) annually by 2045, cumulatively unlocking an additional EUR 880 billion (USD 1.02 trillion) in value creation. AZuR interprets these findings as validation that recycling, reuse and extended product life cycles directly strengthen climate protection, supply security and industrial competitiveness.

A practical model of this transition already exists in the tyre recycling sector, where Germany generates around 50 million used tyres each year. Through professional repair, retreading and regrooving, many of these tyres could remain in use significantly longer before being mechanically or chemically recycled. AZuR actively champions keeping tyres and their raw materials in circulation across Europe, with the clear goals of avoiding waste, lowering CO₂ emissions, conserving natural resources and securing secondary raw materials for industry.

The effectiveness of extending tyre lifespan is illustrated by commercial vehicle retreading, which can increase mileage by up to 25 percent. According to an AZuR and DBU study conducted by the Fraunhofer Institute UMSICHT, retreading saves over 60 percent of CO₂ emissions, roughly two-thirds of raw materials and about 50 percent of the energy compared to new tyre production. Tyres no longer suitable for retreading are then mechanically processed into rubber granulate or chemically recycled via pyrolysis and devulcanisation, yielding valuable secondary materials for construction and new tyre products.

With more than 80 partners across the entire value chain, AZuR networks industry, small and medium-sized enterprises, science and recycling technology to develop concrete circular solutions. The BCG and BDI study thus confirms that the circular economy is not merely an environmental policy issue but a crucial growth driver for Germany’s industrial future, a role that AZuR believes the tire industry is uniquely positioned to lead.
