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)

Liberty Tire Recycling partnered with Henry County staff and volunteers for a three-day Tire Amnesty Event at the County Barn last week, during which thousands of scrap tyres were collected from residents seeking free and responsible disposal. The recurring programme, offered every three years, drew a steady stream of vehicles ranging from cars and trucks to trailers and farm equipment, generating sizable piles of tyres and underscoring both strong community participation and the persistent need for proper recycling.

County personnel, including Jason Stanley, Jeremy Raisor, James Nutgrass, Darrell Abbott, Zach Smith and Travis Buchanan, worked continuously to unload and organise tyres as residents arrived. Among those taking part was New Castle resident Charles Miller, who delivered over 100 tyres, many from demolition derby vehicles, and also brought tyres on behalf of several family members so that materials from multiple properties could be recycled.

Stanley reported that turnout substantially exceeded the previous amnesty event held three years ago, with residents arriving consistently throughout the collection period. Such events offer a convenient way to remove scrap tyres that might otherwise accumulate on properties, create safety hazards and serve as breeding grounds for mosquitoes and other pests, thereby reducing environmental risks and advancing sustainable waste management.

Officials applaud the Kentucky Division of Waste Management and its local partners for organising these programmes, noting that states collecting mandatory tyre disposal or recycling fees can reinvest them in amnesty days that channel waste tyres into the recycling stream and deter illegal dumping. While the final tally remains pending, county officials anticipate the total will rank among the most successful amnesty events in recent years.

Max Verstappen secured his first pole position of the season for the Bahrain Grand Prix, lapping fastest at 1:35.130. Lewis Hamilton took second with a 1:35.428. Pirelli’s Soft compound played a decisive role, as the top three all set their best times on the red-marked tyre. Isack Hadjar originally qualified third but will not start from that grid slot due to a penalty.

Kimi Antonelli, fourth fastest in qualifying, will instead line up third. Hamilton began qualifying on the Medium before switching to the Soft, a strategy mirrored by Charles Leclerc, Nico Hülkenberg and Gabriel Bortoleto. The remaining drivers relied solely on the C4. Verstappen used four new Soft sets and improved his benchmark in the final sector on his last flying run.

Track temperatures peaked at 54°C during FP3 before cloud cover arrived. All three compounds appeared in the session, though most drivers concentrated on the C4. Leclerc alone ran the Hard before moving to a new Soft set. Lando Norris, Oscar Piastri, Verstappen and Hadjar used the Medium, with the reigning champion setting his best time on the C3.

Antonelli topped FP3 at 1:36.302, ahead of Verstappen on 1:36.580 and Hadjar on 1:36.860. The Pirelli Pole Position Award was presented by Alvin Chong, a Malaysian actor and singer recognised across Malaysian and Chinese entertainment.

Dario Marrafuschi, Pirelli Motorsport Director, said, “Track conditions improved progressively throughout the day, allowing the Soft compound to deliver a very competitive level of performance in qualifying. Despite this, lap times remained significantly slower than those predicted by the simulations, indicating that the track evolution was not sufficient to close the gap. In the attempt to extract the maximum potential from the C4 immediately, the degradation generated on the compound meant that no genuinely competitive laps could be completed after the first flying lap today. At the same time, in yesterday’s running it demonstrated that it can maintain an acceptable level of consistency over race distances when it is brought gradually into its correct operating window over the opening laps. This characteristic could prove particularly important tomorrow, given the number of Soft sets retained by several teams.

“Tomorrow’s Grand Prix looks especially interesting from a strategic perspective. Most drivers have two sets of Hard tyres available, which should provide a solid option for the longer stints thanks to their greater thermal resistance and lower degradation compared to the softer compounds. On paper, the Medium-Hard-Hard and Soft-Hard-Hard combinations appear to be among the most competitive. There are, however, some particular situations, such as those of Verstappen and Leclerc, who each have only one set of C2 tyres available and may therefore consider different approaches, making greater use of the Soft and Medium compounds or even evaluating three-stop strategies. In this scenario, the range of possibilities becomes much broader, with shorter stints and increased flexibility. By contrast, we are unlikely to see one-stop strategies, which on paper offer no advantage in terms of total race time at a circuit where overtaking remains possible at several points around the track. Finally, there remains an element of uncertainty related to the weather, with a chance of rain that could influence the teams’ strategic choices.”

American tyre brand General Tire is marking 111 years since its founding on 29 September 1915, when William O’Neil and Winfred Fouse established the General Tire and Rubber Company in Akron, Ohio. What started as a regional tyre maker has evolved into an internationally recognised brand, especially noted for durable tyres suited to SUVs, off-road vehicles and pickups. Since 1987, the company has operated as part of Continental.

The brand’s history tracks closely with the growth of the North American automotive sector. During the 1920s, General Tire earned attention for its ‘General Balloon Jumbos’, which helped push tyre technology forward. As operations grew, the company widened its international reach and became a supplier to major vehicle manufacturers.

William O'Neil, Founder of General Tire

General Tire and Continental first connected in March 1949 through a cooperation agreement covering the exchange of technical expertise and know-how. By the late 1950s, General Tire had opened a tyre testing facility in Uvalde, Texas, then regarded as the largest of its kind worldwide. Continental’s 1987 acquisition opened a new chapter, giving the parent company a global production and sales network for the first time while allowing General Tire to pair its American heritage with worldwide development and manufacturing strength.

Today, the portfolio spans applications from the Grabber GT Plus road tyre and Grabber Cross A/S all-season tyre to the Snow Grabber Plus winter tyre and the Grabber AT3 Plus and Grabber X3 off-road models, all reflecting performance, reliability and American heritage. For the anniversary, General Tire introduced the next-generation Grabber AT3 Plus, an all-terrain successor to the Grabber AT3 with better snow traction, improved wet-road grip and a tread pattern built for demanding off-road use.

Dunlop Motorcycle Europe is set to support a star-studded rider roster at this weekend’s FIM Motocross of Nations (MXoN) in Ernée, France, aiming to cap another standout motocross season. The tyre range available to competitors includes the sand-focused Geomax MX14 for loose surfaces, the intermediate Geomax MX34 and the Geomax MX54, which has become the preferred choice across a wide range of intermediate and hardpack tracks.

The company will supply tyres to 32 riders representing 16 nations, drawing talent from the FIM Motocross World Championship, North America’s Supercross and Pro Motocross series and other competitions. The event follows last weekend’s season-ending MXGP of Australia, with many of the sport’s top names returning to action in pursuit of the Chamberlain Trophy.

Dunlop has built a formidable recent record at the MXoN, having equipped riders from every winning nation over the past four editions. Team Australia took consecutive victories in 2024 and 2025, Team France claimed the title in 2023 and Team USA won in 2022. This year, Australia arrives with an entirely new lineup in Jed Beaton, Alex Larwood and Aaron Tanti, while the United States fields an all-Dunlop trio led by three-time 450 cc AMA Supercross champion Cooper Webb, joined by Julien Beaumer and Levi Kitchen.

For France, MXGP runner-up Romain Febvre spearheads the Dunlop contingent and is joined by fellow Kawasaki Racing Team rider Mathis Valin. Two-time MXGP World Champion Jorge Prado will represent Spain alongside newly crowned MX2 World Champion Guillem Farres. A host of other leading MXGP and MX2 competitors will also run Dunlop, including Camden McLellan for South Africa, Liam Everts for Belgium, Pauls Jonass for Latvia and Jeremy Seewer for Switzerland.

The MXoN serves as a fitting finale to a season of significant success for Dunlop across European and North American series. In the United States, Ken Roczen captured his first 450 cc AMA Supercross title on Dunlop, extending the brand’s streak of winning every AMA Supercross and Pro Motocross championship since 2010.

In the FIM Motocross World Championship, Guillem Farres secured the MX2 crown and led Triumph Racing to a one-two finish with teammate Camden McLellan. The pair combined for 11 of 19 Grand Prix victories. In MXGP, Romain Febvre finished runner-up, while Kiara Fontanesi narrowly missed a historic seventh WMX title, winning at Foxhills in July and adding three second-place finishes.

Wim Van Achter, Motorcycle Motorsport Manager EMEA, Dunlop Motorcycle Europe, “The fact that so many top riders continue to choose Dunlop Geomax tyres underlines the Geomax range’s performance credentials. We work closely with top riders to develop new Geomax products, using their feedback to refine our tyre technology. Our most recent innovation, Geomax MX54, makes the Geomax range our strongest and most versatile motocross range yet, drawing on our knowledge from winning top professional championships. With its broader scope, it could be the tyre of choice for Ernée’s traditional hardpack clay circuit this weekend.”

Eddy Seel, MXGP Event Leader, Dunlop Motorcycle Europe, said, “We are honoured that Dunlop Geomax tyres are the products of choice for 32 of the world’s most talented riders representing 16 different nations. The level of competition is always high at MXoN, but Dunlop has a history of success. Our riders have already proven the performance and reliability of the Dunlop Geomax range all season long, so we’re ready to continue with that this weekend. Allez!”
