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)

Mitas, Official Agriculture Tyre Sponsor of the National Tractor Pullers Association (NTPA) and Title Sponsor of the Mitas National Finals Pull-Off, will occupy the spotlight at the Champaign County Fairgrounds in Urbana, Ohio, on 19 September, when the 2026 Grand National titles are decided.

Serving as the closing Grand National fixture of the season, the 39th Mitas All-Star Pull-Off also wraps up the brand's first year as the association's official agricultural tyre partner. That arrangement forms part of a three-season commitment spanning 2026 to 2028, drawing the company nearer to a North American motorsport discipline where immense engine output, grip and staying power face relentless scrutiny with every pass.

Two tyres will illustrate the breadth of the company's agricultural know-how at the venue. The PowerPull 01 30.5L-32 exists purely for pulling competition, arriving as a smooth tyre devoid of any moulded tread so crews can carve bespoke patterns suited to the track and their own machine setup; its tailored compound and tough build supply the grip, endurance and repeatability the sport requires. The VF 750/60R46 CFO 189D HC1000, by contrast, serves high-capacity self-propelled sprayers and comparable field duties, using Very High Flexion engineering to bear heavy loads at lower pressures while a broad contact patch spreads weight and keeps traction. Its tread delivers grip, longevity and self-cleaning ability for dependable service in punishing conditions.

When the 2026 NTPA season reaches its finale in Urbana, the sport's leading pullers and their followers will gather for a fitting celebration. Mitas will be present throughout, tying together the track and the field by demonstrating how the traction, durability and reliability demanded in competition echo the very traits underpinning its agricultural tyre lineup.

Andrea Masella, Marketing Director, Yokohama TWS, said, "Tractor pulling puts enormous demands on every part of the machine, including the tyres, making it a great environment to demonstrate what traction, durability and reliability mean when performance is pushed to the limit. We are proud to support NTPA as its Official Agriculture Tyre Sponsor and to bring our expertise to the Mitas All-Star Pull-Off. This partnership allows us to connect with the pulling community while highlighting the performance focus behind our agricultural tire portfolio. Pull like a Bull — on the track and in the field."

Michelin has introduced an automated regrooving system called NAZCA, aiming to modernise a retreading practice that has served truck, bus and coach tyre maintenance for more than a century. The manual method demands specialised expertise and now confronts ergonomic strain and a shortage of skilled workers. Developed by Michelin engineers, NAZCA automates the process while following manufacturers’ recommendations, targeting consistent quality and repeatability. The system employs a high-density laser scanner and advanced algorithms to exploit every millimetre of usable rubber.

Because each tyre possesses a unique geometry, NAZCA adjusts cut depth in real time across the tyre’s full width and circumference. After more than a year of real-world testing, the machine can raise the number of regrooving jobs a workshop completes. Michelin estimates a capacity increase of 30 percent to 50 percent, depending on operating conditions. Each regrooving operation requires under three minutes of technician hands-on time, allowing staff to handle alignment, repairs and tyre mounting or removal.

This supports greater workshop profitability and flexibility. NAZCA accommodates a wide range of tyre brands and sizes, provided the casing is robust enough for the lifespan-extending procedure. About 20 NAZCA machines are in pilot testing across Europe. Michelin plans further rollouts in various countries in 2027, subject to applicable regulations, with a gradual commercial launch tailored to each market. The system will appear at the Michelin stand during IAA Transportation in Hannover from 14 to 20 September 2026.

NAZCA forms part of Michelin’s multi-life model, pairing regrooving and retreading so a tyre can last up to 2.5 times longer than a single-life product. Regrooving enables use to the legal wear limit, adding up to 25 percent more mileage and up to 5 percent fuel savings. Retreading completes the approach: initial REMIX retreading can double mileage for roughly 60 percent of a new tyre’s cost, while REMIX 2 premium retreading, available for 90 percent of Michelin truck lines, delivers 95 percent of new-tyre performance for about 60 percent of the cost, cutting cost per kilometre by 33 percent. Each retreading also saves about 50 kg of raw materials per tyre.

Pirelli’s Hard tyre played a decisive role as Kimi Antonelli won the inaugural Formula 1 race at the Madring, mastering a one-stop strategy to take victory in the Spanish Grand Prix. The Mercedes driver finished ahead of Max Verstappen and Lando Norris, extending his World Championship lead in the process.

All three podium finishers made their sole pit stop during a Virtual Safety Car period between laps 14 and 15. Antonelli and Norris swapped Pirelli Mediums for Hards, while Verstappen replaced his starting Softs with Hards. The one-stop approach proved dominant across the grid, with only George Russell, Carlos Sainz, Oliver Bearman, Fernando Alonso and Valtteri Bottas stopping twice.

Track temperatures peaked at 52°C and air temperature reached 32°C, mirroring conditions from earlier in the weekend. Russell, Antonelli’s closest title rival and team-mate, came home fifth. Antonelli now leads the standings on 292 points, with Russell second on 211. The Azerbaijan Grand Prix follows on Saturday 26 September.

In supporting action, Dino Beganovic won Sunday’s Formula 2 Feature Race ahead of Alex Dunne and Ritomo Miyata, all three running Softs before Hards and pitting on lap 18. Ugo Ugochukwu secured the Formula 3 World Championship by finishing second in Madrid, as Freddie Slater’s eighth place allowed the title swing. Tuukka Taponen won the finale, with Pedro Clerot third.

Dario Marrafuschi, Pirelli Motorsport Director, said, “The teams approached today's race differently from what had been simulated on track on Friday. Thanks also to the opportunity provided by the Virtual Safety Car, they favoured a more measured management of pace and degradation, which allowed them to significantly extend stint lengths and made the one-stop strategy the preferred choice for the majority of the field. The star of the Grand Prix was the Hard tyre, a compound that had been little explored during free practice and which today demonstrated a very high level of consistency, proving to be the most robust of the three compounds from both a thermal and mechanical perspective. With the C2, we saw several stints exceeding 45 laps, reaching very high levels of wear without any significant performance drop-off. Both the Medium and the Soft also proved to be effective options despite the track temperatures. The C4, in particular, completed competitive stints comparable to those of the Medium in terms of durability.

“As expected, graining appeared mainly on the front-left tyre, on the inner area of the tread, but with limited intensity. The work carried out by the teams on car setup and tyre management helped to minimise its effects. In a race characterised by few overtaking opportunities, the drivers were able to focus on tyre management, contributing to a very straightforward contest from a strategic perspective. Congratulations to Ugo Ugochukwu for securing the Formula 3 championship title today at the end of a highly competitive season. The series continues to represent an important proving ground for young talents from all over the world. The fact that the title was decided only at the final round highlights the exceptionally high level of competitiveness within the championship, which this year delivered spectacular racing and outstanding sporting value.”
