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)

Yokohama Tire’s off-road racing contingent is set for a pivotal appearance at the 57th annual Polaris World Championships, scheduled for 4–6 September at Crandon International Raceway in Wisconsin. Known as ‘The Big House’, the venue represents a key stop on the Championship Off-Road season calendar, with Yokohama serving as both the official tyre of the facility and a supporting partner of the racing series.

The team’s lineup features several notable competitors navigating the rugged terrain on GEOLANDAR tyres. Andrew Carlson, a proven contender with multiple podium finishes at Crandon, will pilot his vehicle in the Pro4 class using GEOLANDAR X-AT tyres. Meanwhile, recent Supercross 450 Class Champion Ken Roczen is slated to make his debut at the historic track, competing in the Pro2 class on the same tire model.

Robb Holland is also poised for his first Crandon appearance, trading asphalt for dirt in the Pro Lite division. He will drive a truck belonging to fellow Team Yokohama driver John Holtger, relying on GEOLANDAR A/T4 tyres for his inaugural short-course off-road race. Additionally, team driver Nick Visser enters the weekend holding a narrow lead in the Pro-Spec championship standings, with the title battle intensifying as the season progresses.

Beyond the on-track action, Yokohama will lead the traditional Crandon Labor Day Parade, featuring Carlson and Roczen. The weekend will also include a BassmastHER workshop hosted by Cogan and Carsello, aimed at advancing skills for female participants in the paddock, alongside a VIP and youth fishing tournament held on-site.

Candace Cogan, Director – Product Marketing, Yokohama, said, “We’ve got a great team ready to take on the challenges at Crandon during short-course racing’s most celebrated weekend. They will be ready to face the task on our versatile line of GEOLANDAR tyres. We will once again feature our partnership with Bassmaster with a cool collaboration. Last year we hosted Team Yokohama elite angler, Brandon Palanuik. This time we’ll host Wisconsin native MaggieJo Carsello, a Bassmaster open angler and ambassador for BassmastHER, a female-driven initiative to support a community of female anglers via education, travel and inspiration. We look forward to introducing her to Crandon and the world of short-course off-road racing, something she grew up hearing about.”

Kumho Tire USA recently hosted a national Ride & Drive event at Evergreen Speedway in Monroe, Washington, where over 70 dealers, media professionals and content creators tested the company’s newest tyre models. The gathering served as a key component of Kumho’s broader 2026 regional tour, which has already engaged more than 600 participants across five American cities. Attendees evaluated the newly launched Road Venture HT and Crugen GT Pro tyres through demanding, real-world driving scenarios.

The testing programme featured controlled modules, including a wet handling course, an autocross track for braking and stability assessment and high-speed freeway driving to measure ride comfort. These exercises allowed participants to directly compare the all-season Highway-Terrain Road Venture HT, intended for light trucks and SUVs, against the Crugen GT Pro, a touring tyre built for modern crossovers and larger SUVs. Kumho’s engineers also conducted an educational forum detailing the technological development of both tyres while collecting direct feedback from attendees.

The Road Venture HT, launched earlier this year, offers enhanced wet and snow traction, extended tread life and a quiet ride, and is compatible with electric vehicles. The Crugen GT Pro is engineered for heavier crossover and SUV applications, delivering premium comfort and all-weather capability with one of the highest treadwear warranties in its segment. Available in 85 sizes covering over 85 percent of the current crossover and SUV market, the Crugen GT Pro is backed by a 75,000-mile warranty for H- and V-speed ratings and a 65,000-mile warranty for W-speed models.

Kumho will conclude its 2026 Ride & Drive series with final regional events in Detroit and St. Louis later this month. The company has confirmed plans to extend the programme into 2027 and beyond, ensuring dealers and partners continue to benefit from hands-on product evaluations, technical training and direct access to Kumho’s engineering expertise.

Chris Corwin, Director of Procurement at Discount Tire & Service Centers, said, "A spec sheet has never sold a tyre to a customer standing at our counter. That is why the Kumho Tire Ride & Drive in Seattle was worth every minute. We got real seat time, instead of a sales pitch, running the all-new Crugen GT Pro and Road Venture HT back-to-back in real world scenarios. Having a seat at that table means a lot to me, and it says something about how seriously they take dealer input."

Ed Cho, CEO, Kumho Tire USA, said, “You can read all about a tyre, but nothing compares to driving it yourself, which is why KUMHO has made a significant investment in Ride & Drive events in 2026. These events give our dealers, wholesale partners and retail partners the opportunity to experience firsthand how our latest tyres perform in real-world driving situations. Whether they are evaluating braking, handling, ride comfort or overall performance, attendees can experience the differences for themselves, giving them greater confidence when recommending our products to their customers.”

The AZuR Circular Tyre System has been nominated for the German Sustainability Award Products 2026 in the ‘Resources’ transformation category. This selection places the initiative among solutions deemed by the expert jury as pioneering for advancing a resource-conserving economy.

This circular economy model spans the entire tyre lifecycle, uniting industry partners, retailers, recycling specialists and academic institutions. The framework optimises tyre usage and guarantees high-quality raw material recovery. Repair, reprofiling and retreading prolong useful life, while tyres beyond repair undergo mechanical or chemical recycling to recover valuable secondary materials.

Rather than relying on a single technology, the system's distinctiveness lies in networking stakeholders across the value chain. The award's evaluation highlighted the system's ambition to extend product longevity, prevent waste and sustain raw material circulation, thereby reducing demand for virgin resources.

German market data for 2024 shows approximately 533,000 tonnes of used tyres generated, with 193,000 tonnes mechanically recycled and 20,000 tonnes retreaded. Research indicates retreaded tyre production can reduce CO₂ emissions by over 60 percent, lower raw material usage by two-thirds and cut energy consumption by 50 percent compared to new tyre manufacturing. Products from tyre granulate can save between 1.0 and 3.2 tonnes of CO₂ equivalent per tonne of recycled material.

The nomination drives AZuR to advance Europe's tyre circular economy through extended lifespans, strengthened recycling and digitalisation. The 2026 award winners will be announced on 3 December in Düsseldorf.

Anna Maria Guth, AZuR network coordinator, said, “The nomination is a great recognition for all partners who are working together to further close the tyre cycle. It also shows that the circular economy can be particularly successful when companies, science and other stakeholders do not act in isolation but jointly develop solutions along the entire value chain.”

Bridgestone has released research indicating that over 80 percent of UK motorists believe basic tyre knowledge should be mandatory for new drivers during learning and after passing their test. The survey found that 81 percent of respondents want new drivers to understand correct tyre pressures, tread depth regulations and tyre pressure monitoring systems. Additionally, 57 percent expressed support for graduated driving licences aimed at young motorists, reflecting broader calls for enhanced safeguards during early independent driving.

The findings also reveal strong public backing for more rigorous enforcement, with 67 percent of motorists advocating for tyre safety inspections during routine police traffic stops. Beyond individual owners, 76 percent of respondents asserted that employers should bear greater responsibility for ensuring tyres on all work-related vehicles are properly maintained. Furthermore, 78 percent called for dedicated tyre safety education to be introduced for young people before they reach driving age, underscoring a collective desire for preventative measures that begin well before a first lesson.

The survey results coincide with newly published Department for Transport data showing a significant deterioration in tyre-related road safety outcomes. The number of people killed or seriously injured in collisions involving illegal, defective or underinflated tyres rose by 19 percent year on year, from 169 casualties in 2024 to 201 in 2025. Overall, tyre-related incidents accounted for 667 casualties during 2025, a 14 percent rise from 585 the previous year, while collisions attributed to defective tyres climbed to 447.

This research builds upon Bridgestone’s 2025 study, which identified substantial backing for additional protective measures for novice drivers. Half of respondents supported displaying a recently passed sign for up to 12 months and limiting new drivers to one passenger during their first year, while 39 percent favoured a mandatory refresher course after passing the test and 21 percent endorsed restricting new drivers to a 50-mile radius from home for 6 to 12 months. The findings reinforce Bridgestone's Road Safety Hero campaign, promoting regular tyre checks as part of the company's broader E8 Commitment to enhance driver safety and sustainable mobility.

Helen Roe, Senior Marketing Manager, Bridgestone UK, said, “The latest findings reinforce our belief that tyre safety should play a far greater role in helping young drivers develop safe driving habits from day one. Despite tyres being the only point of contact between a vehicle and the road, tyre maintenance remains one of the most overlooked aspects of vehicle safety. We have seen some high-profile cases of preventable road fatalities due to defective tyres and we can’t stress the importance of knowing the tyre basics and carrying out some simple checks, which can be done in a matter of minutes.

“Learning to drive doesn't stop the day someone passes their test. Developing safe habits, including understanding how to check and maintain tyres, is an important part of becoming a confident and responsible driver. It's encouraging to see such strong public support for improving tyre safety education and ensuring motorists understand the importance of looking after the only part of the vehicle that actually touches the road. Simple checks can make a real difference to road safety, not only for new drivers but for everyone using our roads.”
