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)

Hankook Tire, the exclusive tyre supplier to the FIA World Rally Championship (WRC), successfully completed the sixth round of the 2026 season, the Vodafone Rally de Portugal, where its Dynapro R213 rally tyre played a central role in managing the event’s punishing conditions. The tyre was engineered to absorb impacts from rough gravel and rocky terrain while delivering consistent grip and durability across the rally’s demanding stages.

Held from 7 to 10 May around Matosinhos in northern Portugal, the competition covered 23 Special Stages totalling approximately 345 kilometres. The surface began as soft, sandy gravel but progressively turned into sharp rocks and deeply rutted terrain due to repeated passes, making tyre durability and stability essential for performance. Hankook provided the Dynapro R213 in Hard and Soft compounds, allowing teams to balance high grip from the soft version with the hard compound’s resilience on changing surfaces.

After a fierce battle, Hyundai Shell Mobis World Rally Team driver Thierry Neuville secured overall victory, marking his team’s first win of the 2026 season. He took the lead in the closing stages and delivered a commanding performance to finish on the top step of the podium. In the Drivers’ Championship standings, Toyota GAZOO Racing’s Elfyn Evans leads with 123 points, followed closely by teammate Takamoto Katsuta on 111 points.

Throughout the event, Hankook operated a Brand World booth in the service park, featuring a motorsport heritage exhibition, racing simulators, branded merchandise and photo zones to enhance its premium global image. The 2026 WRC season now moves to Round 7, the FORUM8 Rally Japan on 28–31 May, a tarmac event on narrow mountain roads requiring precise steering and high-speed stability. Hankook continues to integrate WRC driving data into its R&D, advancing high-performance tyre technology as the exclusive supplier for all WRC classes since 2025.

DUNLOP Motorsport is all geared up for the 2026 ADAC RAVENOL 24h Nürburgring, scheduled to be held from 14 to 17 May 2026. At the legendary Nordschleife, the team will debut a Porsche 911 GT3 R bearing start number 17, marking the black-and-yellow car’s first appearance at the Eifel classic. A quartet of experienced drivers has been assembled to share the cockpit, including Frenchmen Julien Andlauer and Dorian Boccolacci, Belgian Alessio Picariello and Nordschleife specialist Nico Menzel.

A series of preparatory runs within the ADAC RAVENOL Nürburgring Endurance Series allowed the team to gather vital operational intelligence. Despite a rain‑affected delay to the opening round, the group managed to cross the line inside the top ten overall during its very first race. That outcome, combined with methodical calibration of the Porsche's suspension and aerodynamics, improved the squad's command of DUNLOP tyre behaviour under race conditions.

Unpredictable factors such as sudden showers, evolving asphalt grip and heavy lapped traffic frequently decide outcomes at the Nürburgring. Success therefore hinges on error‑free driving and disciplined strategic calls. The selected drivers bring precisely those attributes: Andlauer from his tenure in elite GT and prototype series, Boccolacci and Picariello from repeated Nordschleife campaigns, and Menzel from years of local expertise.

Several other entrants have also chosen DUNLOP rubber. Saugmotoren Motorsport will run the distinctive BMW Z4 E89, steered by Nordschleife veterans Ralf Schall and Christian Scherer. BLACK FALCON Team FANATEC, collaborating with Gran Turismo, enters a Porsche 911 GT3 Cup whose cockpit will be shared by Manuel Metzger, online personality Misha Charoudin and sim racers Steve Brown and Jimmy Broadbent. For spectators, the Boulevard area presents an interactive zone where Gran Turismo simulators offer virtual Nordschleife laps. A Porsche 962 C on loan from the Porsche Museum, winner of all five Supercup races in 1987 and that year's champion, will also be exhibited.

The ADAC RAVENOL 24h Nürburgring starts Saturday 16 May at 3:00 pm. Fans unable to attend can watch live via the official stream or on RTL Nitro. DUNLOP Motorsport also shares regular updates and content from the Eifel region through its social media channels.

Pirelli has developed a new rear tyre solution for the fifth FIM Superbike World Championship round at the Czech Republic’s Most circuit. The track is known for unusually high mechanical strain on rubber, particularly at the rear axle. To address this, Pirelli created the F0468 medium compound rear specification. Its compound matches the D0922, a tyre used at Most in 2025 and at Phillip Island across the previous two seasons. However, the F0468 features an entirely new internal structure for better race-long consistency and improved stability.

This newcomer evolves the E0829 specification, which shared the same compound and appeared at Phillip Island earlier this year. Riders who dislike the F0468 can still choose the D0922 development rear tyre. That option has already proven itself at the unique Czech layout and at Phillip Island, another tyre‑killing circuit. For qualifying and the Superpole Race, Pirelli has designated the standard soft SC0 as the reference rear tyre.

Beyond the premier class, Supersport and SportBike World Championship competitors will also race at Most. Supersport riders receive the same front choices as Superbike: soft SC1 and medium SC2. At the rear, Supersport entries can pick the soft SC0 or the medium SC1. SportBike competitors have used that same medium SC1 on both axles all season.

The tyre lineup thus gives every category familiar options alongside the new F0468. By blending a proven compound with a revised structure, Pirelli targets greater performance consistency without forcing riders to abandon the trusted D0922. Most’s punishing layout will serve as the ultimate test for both solutions.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Over more than two decades as supplier to the Superbike World Championship, Pirelli has built an extremely solid and versatile tyre range. The SCX supersoft rear solution now represents an absolute benchmark for riders and is used in most races on the calendar, with the soft SC0 becoming a valid alternative on some occasions. There are, however, some circuits that are particularly demanding on tyres, such as Phillip Island and Most, which by virtue of their layout and intrinsic characteristics require more specific solutions and more durable compounds, typically medium options.

“In these cases, development work focuses on improving key parameters such as performance and consistency over race distance: objectives that guided the design of the new rear solution in F0468 specification. To complete the allocation, riders will in any case also have the well-proven D0922 option available, which has shown that it can effectively handle the particular stresses imposed by this circuit. It will be interesting to assess whether the new F0468 medium will be able to raise the performance level beyond that of the D0922 further still.”
