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?

The N Vision intelligent tyre from Maxxis has strengthened its resolve for innovation and sustainability by winning the gold A’ (A-Prime) Design award. The tyre was recognised in the Vehicle Parts, Auto Accessories and Care Products design category.

N Vision, which was created for the autonomous vehicles that are expected to be commercially available in 2030, makes use of information from several sensors to forecast tyre condition, vehicle load, speed and road conditions. By modifying the spokes' stretch and bending in response to such circumstances, it gives the tread area the best possible pre-compression or pre-tension. In the end, this lowers the cost of travel per mile. In order to maximise sustainability, N Vision was built using recycled materials made from fishing nets, tyres and PET bottles, as well as bio-based components made from rice husks and sunflower seeds. Tyre scrapping is decreased by its environmentally friendly design and materials, which also give customers an inexpensive, renewable travel choice.

A jury composed of 316 top designers, scholars and prominent members of the press selected the winners of the international A' Design Award competition, which recognises excellence in design in a wide range of fields, including transportation, hospitality, furniture, beauty and much more.

The Victra Sport 6 and HP6 tyres from Maxxis have won the Red Dot Product Design Award for 2025 in the Vehicle Accessories category.

The Maxxis Premitra HP6 features improved rolling resistance, effective braking, a smooth ride, improved mileage for longer travel and accurate handling in wet situations. Designed for sport and luxury automobiles, the Maxxis Victra Sport 6 is an ultra-high-performance tyre that works well with electric and plug-in hybrid vehicles. It offers outstanding handling and performs quite well at sporty, faster driving. Both the tyres are available in Europe.

Red Dot Award winners are selected by a panel of 40 worldwide professionals who test, analyse and assess each entry in one of the biggest design contests in the world. The categories for awards include Design Concept, Brand Communication and Product Design. Winners will receive the Red Dot trophies during a banquet in Essen, Germany, on 8 July.

Continental's SportContact 7 tyre has emerged the test winner in this year's Auto Bild sportscar summer tyre test (issue 6/25) with an overall grade of 1.2 (exemplary).

Seven tyre models in the sizes VA 245/35 R 20 and HA 295/30 R 20 from European, Asian and American manufacturers were tested by the editors. The Lotus Emira served as the test car. The SportContact 7 scored top marks in wet handling, cornering, braking and aquaplaning. It had a 43.7-metre braking distance from 100 kmph on wet asphalt, which put it four metres ahead of the second-place tyre and eleven meters ahead of the last-place tyre. It clinched an intermediate score of 1- for the wet tests, which puts it far ahead of its rivals in the test field. After 31.2 metres at 100 kmph in the dry testing, the tyre came to a complete stop. Overall, the tyre received an intermediate 1- throughout the five dry categories.

The SportContact 7 is specifically made for high-performance sports cars that may be powered by electricity or conventional power. Several automakers have authorised it, and it comes in sizes ranging from 18 to 24 inches. Continental concentrated on achieving excellence in every performance criterion throughout development in order to maximise driving enjoyment and safety.

Andreas Schlenke, tyre expert at Continental, said, "The SportContact 7 took first place in the AUTO BILD sportscar test in both wet and dry conditions. This once again proves its leading position in the sports and UHP tyre segment.”

The final verdict from the tyre testers read: "Conti's sport tyre sets the standard for braking on dry and wet roads and offers a big plus in driving safety. Stable, well-balanced handling on dry roads.”

The U.S. Tire Manufacturers Association (USTMA) has welcomed the bipartisan passage of H.J.Res. 61, a resolution that improves environmental stewardship and lessens financial constraints on tyre manufacturing plants.

The resolution, co-sponsored by more than 20 representatives from 14 states and introduced by Representative Morgan Griffith (R-Va.), repeals the EPA's 29 November 2024 updated rule on Rubber Tire Manufacturing National Emissions Standards for Hazardous Air Pollutants (NESHAP). With nine co-sponsors, Sen. Tim Scott (R-S.C.) spearheaded the campaign in the Senate with S.J.Res. 24. Before the House vote, USTMA sent in a letter of support for the measure. 

According to the EPA's own evaluation in 2020, the current guideline offers a sufficient margin of safety to safeguard human health and avert a negative environmental impact. On 29 November 2024, however, the EPA released an updated final NESHAP rule that added emission restrictions for total hydrocarbons (THC) and filterable particulate matter to the current NESHAP regulation, in defiance of the agency's own judgment. Because of this, tyre factories must build and run a large number of control devices called regenerative thermal oxidisers, which require a large amount of natural gas to burn impurities. In an effort to lower insignificant HAPs, these new control devices raise carbon emissions while placing a heavy financial burden on tyre manufacturing facilities with no clear emissions reduction target.  

The EPA's objective to protect America's clean air is shared by USTMA member companies. In order to reduce the negative impacts on the American tyre manufacturing business, the environment and the American economy, the USTMA supports Congressional action to overturn this final rule, even as it continues to collaborate with the EPA, the association stated.

Anne Forristall Luke, President and CEO, USTMA, said, “Tyre manufacturers have long understood and complied with the existing NESHAP standards to reduce hazardous air pollutant (HAPs) emissions from tyre manufacturing. However, the agency’s revised final NESHAP rule creates an adverse environmental impact, while imposing significant financial burdens on tyre manufacturing facilities and providing negligible, if any, benefits. The industry appreciates the Congressional leadership and bipartisan efforts in getting this resolution passed.”
