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)

The AZUR network has declared 10 May 2026 a pivotal date for Germany’s ecological balance, marking the country’s Overshoot Day, which is calculated by the Global Footprint Network. From this point forward, the nation’s resource consumption for the remainder of the year will be living beyond environmental means. If the global population mirrored German habits, three planets would be required to meet resource demands. For AZUR, this calculation serves as an urgent directive for the tyre industry to adopt a circular economy without delay.

The tyre sector stands at the centre of this challenge, with roughly 600,000 tonnes of used tyres generated annually in Germany. According to AZUR, this waste stream represents either a severe environmental liability or a valuable secondary raw material source, depending on handling. The early Overshoot Day underscores that the linear production model has reached its limit, compelling a consistent ecological transformation.

Within its network, AZUR promotes three strategic approaches to tyre recycling. Retreading old tyres conserves up to 70 percent of the energy and virgin materials like natural rubber and steel compared to new production. Mechanical recycling recovers rubber meal and granules, keeping resources circulating rather than sending them to incinerators. Chemical recycling via pyrolysis breaks down tyres under heat without oxygen to produce pyrolysis oil, recovered carbon black and gas.

The 10^th of May thus stands as a reminder that resource inefficiency is no longer acceptable. By uniting industry specialists, AZUR aims to shrink mobility’s ecological footprint and progressively push Germany’s Overshoot Day later into the winter months in the years ahead.

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.”

Prinx Chengshan showcased its latest off-the-road tyre innovations at the 16th China (Guangrao) International Rubber Tire & Auto Parts Expo (Guangrao Tire Expo), which opened on 15 May. The event has established itself as one of China’s largest and most influential professional exhibitions in the rubber and tyre industry, focusing on uniting global tyre resources and fostering collaborative innovation and high-quality development.

The manufacturer’s exhibition focused on the Chengshan brand’s lineup of all-steel OTR and agricultural radial tyres. For heavy mining applications, the ET05/ET05A/ET16/ET17 wide-body dump truck tyres with deep transverse grooves offer strong traction on soft, uneven surfaces while preventing slippage. An all-terrain crane tyre, EC01, featured a non-directional tread and sidewall heat dissipation holes, balancing grip with temperature control for smooth travel between paved and unpaved roads. The ELD11/ELD12 loader tyres emphasised wear resistance and load stability under extreme conditions, and the ESM01 underground scraper tyre featured an ultra-cut-resistant compound to protect against sharp rocks in tunnel and mine settings.

Agricultural needs were addressed with the TX600 radial tyre, built for tractors operating on expanding modern farms. Large central tread blocks and flexible sidewalls support stable high-speed transit, while reinforced base structures and puncture-resistant materials allow for continuous work in fields containing crop straw and gravel.

Responding to growing OTR demand, Prinx Chengshan has accelerated its high-end product development to support domestic substitution in large machinery. A new green intelligent factory, representing an investment exceeding RMB 1.1 billion (approximately USD 161.75 million) across over 100,000 square metres, began operations in 2025 with the rollout of its first tyre. The facility is designed to produce 84,000 all-steel OTR tyres and 10,000 giant tyres annually for mines, construction sites, ports, airports, agriculture and industrial use.
