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 has underscored the competitiveness of its winter and all-season portfolio through strong showings in two recent independent assessments. The Kinergy 4S 2 all-season tyre and the Winter i*cept RS 3 winter tyre both earned top-tier results in tests conducted by Auto Zeitung, in its issue 20/2026, and by the Automobilclub von Deutschland (AvD) in August 2026. The evaluations positioned the manufacturer’s products favourably across multiple performance and economic criteria.

In the Auto Zeitung all-season comparison, the Kinergy 4S 2 was assessed in the widely used 225/45 R 17 fitment and received the publication’s ‘Highly recommended’ designation. The tyre demonstrated notable composure on snow, with predictable cornering behaviour that testers described as making it a comfortable winter-capable option. It also excelled in aquaplaning resistance while cornering and recorded the quickest wet-handling lap on the circular track. On dry surfaces, the editorial team noted trouble-free behaviour at the limits, solid projected mileage, and strong value for money.

The AvD’s 2026 all-season test delivered similarly positive outcomes. Evaluated in size 225/50 R 17, the Kinergy 4S 2 claimed the best value-for-money ranking and performed strongly in the economy and environment category, earning 4.78 out of five stars overall. It achieved five stars each for mileage and fuel consumption, along with 4.9 stars for tyre wear. Against a twelve-tyre field, it also placed highly for aquaplaning and aquaplaning in curves, securing 4.20 stars in the final ranking and an overall ‘Good’ rating.

Separately, the Winter i*cept RS 3, tested in 225/45 R 17, received an overall ‘Good’ verdict with 4.26 stars in the AvD winter tyre evaluation. It performed particularly well in snow braking and traction, scoring 4.4 and 4.3 stars, and in aquaplaning in curves and straight-line aquaplaning, with 4.5 and 4.4 stars. The tyre also earned 4.43 stars across economic and environmental criteria, including 4.6 stars for weight and 4.5 stars each for fuel consumption, mileage and tyre wear.

Bridgestone Corporation has confirmed it will become the exclusive tyre supplier for the ABB FIA Formula E World Championship, the foremost all-electric motorsport series, beginning with the 2026/27 season. The announcement positions the Japanese manufacturer at the centre of a championship that has grown into a global platform for electric racing since its founding in 2014.

The forthcoming season will mark the competitive debut of the GEN4 car, a machine that redefines performance boundaries. With permanent active All-Wheel Drive, remarkable torque and acceleration, the GEN4 reaches 100 kmph in 1.8 seconds and attains a top speed of 335 kmph, while producing a peak output of 815 bhp. These figures make it the quickest and most potent Formula E vehicle ever built.

To harness this performance, Bridgestone has engineered the POTENZA GEN4 tyre, designed to deliver high grip, broad adaptability across varied road and weather conditions and durability that sustains performance throughout a race. A second specification, the POTENZA GEN4 for TYPHOON TYRE, has also been created to ensure stable handling and strong grip when heavy rain leaves substantial water on the track.

Sustainability features prominently in the tyre programme. Each GEN4 tyre incorporates a 65 percent allocation of recycled and renewable materials, including carbon black recovered from pyrolysis oil of end-of-life tyres and silica derived from rice husks. Natural rubber is drawn from supply chains subject to Bridgestone due diligence, compliant with the GPSNR Assurance System and verified by an independent third party. Manufacturing uses 100 percent renewable energy for both heat and electricity, while low-carbon logistics help curb CO₂ emissions, with chemical recycling of end-of-life tyres among wider value-chain initiatives pursued alongside partners.

Formula E, governed by the FIA, has expanded rapidly through street races in cities such as Monaco, Sao Paulo, Sanya and Tokyo, alongside traditional circuits. Its digital engagement and programmes such as FIA Girls on Track have helped build a fan base exceeding 400 million. Committed to Making Progress Thrilling, the championship demonstrates that electric racing can drive measurable change rather than merely inspire.

The Bridgestone Formula E World Premiere, held in Rome on 30 September ahead of the 2026/27 season, drew representatives from the FIA, Formula E, teams, drivers, international media and influencers. Global CEO Yasuhiro Morita shared his enthusiasm for the entry, while Chief Product Officer for Global Motorsports Hiroshi Imai and WEST Chief Technology Officer Emilio Tiberio detailed the tyre technology behind the GEN4.
