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)

Pirelli has chosen the softest trio in its range for the Mexico City Grand Prix, with the C3 as Hard, the C4 as Medium and the C5 as Soft. This departs from last year, when a compound step using the C2 as Hard proved less appealing than the softer alternatives. The second round of the Americas triple-header takes place at the circuit named after brothers Pedro and Ricardo Rodríguez, unique on the calendar due to its altitude of over 2,000 metres.

A large portion of the circuit has been resurfaced, covering Turn 16 to Turn 1 and Turn 7 to Turn 16, leaving only the first sector largely unchanged. New asphalt normally brings higher grip and lower roughness, though its actual characteristics will need assessment during the opening stages. The track is often dirty early on, with grip improving lap after lap, and that evolution could be more pronounced this year.

The Autódromo Hermanos Rodríguez has traditionally been one of the least demanding circuits on tyres, with low-speed corners and limited lateral loads keeping wear under control. The thin air reduces aerodynamic load, increasing tyre slip and making graining a factor to watch, possibly more so with the smoother asphalt. The circuit's low severity could favour a one-stop race, though tyre management to extend stints will remain important, particularly for the rear axle.

Strategy may depend more on driver confidence in a compound than on genuine tyre life limitation, with some teams favouring softer compounds for grip and others the Hard for consistency. The Soft could play a central role, having shown strong characteristics on low-severity circuits. Braking performance also warrants monitoring, as the altitude reduces aerodynamic efficiency and the long main straight into Turn 1 could increase lock-up risk. Last year's grid was split between one-stop and two-stop strategies. This will be the sixth Grand Prix under the Mexico City Grand Prix name, with Max Verstappen the most successful driver at the venue with five victories, matching Red Bull. The Pirelli Podium Cap celebrates Día de los Muertos, which falls on race Sunday.

The U.S. Tire Manufacturers Association (USTMA) has published its 2025 End-of-Life Tire Market Report, continuing a biennial series begun in the early 1990s. With over 30 years of figures on tyre generation, destination markets and stockpiles, the study stands as the nation's most thorough accounting of what happens to tyres after they leave the road.

Of the 273 million tyres retired nationwide in 2025, some 79 percent were absorbed by end-use markets. Only lead-acid batteries surpass tyres as a recycled and reclaimed material; paper, aluminium, glass and PET plastic all trail behind. The result is that valuable rubber stays in productive circulation rather than accumulating in landfills.

Abandoned and illegal stockpiles shrank to roughly 42.1 million tyres, compared with about 48 million two years earlier – a 12 percent drop in that span and a 96 percent fall from the billion-tyre high of 1990. Colorado's cleanup effort accounted for much of the gain, eliminating over 12 million tyres, while New Jersey and Pennsylvania recorded large reductions. North Carolina, Tennessee and Delaware cleared their stockpiles entirely, and land disposal declined nearly 11 percent to 779 thousand tonnes.

Tyre-derived fuel stayed the biggest outlet, taking about 1,317 thousand tonnes, with ground rubber just behind at roughly 1,201 thousand tonnes. Cement kilns consumed about 5 percent more, reaching 821 thousand tonnes – 62 percent of all tyre-derived fuel – as carbon-reduction mandates and the fuel's biogenic nature enhance its appeal. Reclamation applications expanded by roughly a tenth.

Most declines arose from forces outside the industry's influence. Pulp and paper mill shutdowns halved nothing less than 40 percent of that outlet, while revised Michigan energy rules trimmed utility boiler demand by about 22 percent. Synthetic turf continues yielding ground to cork, coconut husk and olive pit infill; moulded and extruded goods eased from a 2021 high; and energy price swings have shifted tyre-derived fuel's competitiveness. Exports, however, climbed 270 percent since 2023 – from 253 thousand tonnes to 936 thousand tonnes – making them the third-largest outlet, driven by India's rapid growth and sustained fuel shipments to Japan and South Korea. USTMA urges exporters to confirm that receiving markets are environmentally sound and economically viable.

Near-term investments include Tire Recycling Foundation-backed environmental product declarations, wider chip seal use, advances in dry-process rubber-modified asphalt and pavement funding. Kentucky devoted over USD 1.16 million in 2025 to nine county rubber-asphalt projects, and California opened USD 6.57 million in grants for fiscal 2025–26. Pyrolysis is now quantifiable as it reaches commercial scale, and the Tire Recycling Foundation is growing into a platform for education, research and demonstration. State-level stockpile figures accompany the report on the ELT Report page of the association’s website.

Anne Forristall Luke, president and CEO, USTMA, said, “This report gives a picture of a market in transition. Stockpile cleanup continues, and 79 percent of end-of-life tyres reached end-use markets. At the same time, several domestic markets contracted, and the rise in exports shows strong demand for this material outside the US Together, those trends tell us our markets still depend on a handful of large industrial outlets, and that market development has to be the priority. The data points to where the work is needed, and much of that work is already underway.”

Amelia Chucholowski, Associate Director, Sustainability and Recycling Policy, USTMA, said, “International demand further demonstrates that this material has real value, but our priority is domestic circular end-use markets, because a tire processed here supports a US recycler, US jobs and US infrastructure. That includes ensuring that domestic processors have adequate feedstock. We’re watching it closely and working with our global partners both to understand what’s driving this trend and to report it transparently.

“The work that actually grows these markets is underway right now, and almost none of it shows up in a 2025 market report. Read this report as a snapshot of 2025. What we’re building now will be measured against in the future. State programmes have built one of the country’s great recycling success stories. 96 percent of the tyre stockpiles that existed in 1990 are gone, and the lesson is clear: when states fund their programmes, enforce the rules and invest in markets, results follow. The next chapter is about markets. The more states invest in uses like rubber-modified asphalt, the more tires become roads, products and energy here at home.”
