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)

AI mobile data capture company Anyline has reported that approximately 15 percent of tyres inspected across United States during National Tire Safety Week, observed from 29 June to 5 July 2026, registered tread depths below the critical safety threshold of 3/32 of an inch. The analysis was derived from all professional-grade inspections conducted nationwide using the company’s TireBuddy application during that seven-day period.

Industry observers suggest the actual prevalence of unsafe tyres on American roads may be significantly higher, as motorists who voluntarily participate in inspection events typically exhibit greater safety awareness than the general driving population. This self-selection bias implies that the overall percentage of worn tyres among all vehicles likely exceeds the recorded figure.

The data emerges against a backdrop of approximately 11,000 annual tyre-related traffic incidents documented by the National Highway Traffic Safety Administration, many of which involve tyres that showed no prior visible warning signs. National Tire Safety Week was established as an educational initiative to address this gap, given that gradual tread wear remains one of the most easily preventable contributors to highway accidents yet often goes unnoticed by drivers.

On 2 July 2026, Giti Tire collaborated with Anyline to host a complimentary inspection event at its North American headquarters in Charlotte, North Carolina. Participants received an artificial intelligence-powered tread measurement via the TireBuddy app alongside a pressure check, with both metrics compiled into a single visual report. The U.S. Tire Manufacturers Association advises motorists to conduct such evaluations at least once every two months.

William Estupinan, Vice President – Technical Service, Giti Tire, said, “We believe tyre maintenance education is most effective when it's personal. Providing drivers with a tread scan and air pressure reading for their own tyres brings tyre maintenance messages to life in a way that's meaningful and actionable.”

Christoph Braunsberger, CEO, Anyline, said, “Road safety is built from small, routine decisions and few are overlooked as tyre condition. National Tire Safety Week brings that risk into focus and reminds drivers how much a simple check can reveal. Our role is behind the scenes: giving the technicians who carry out inspections a more accurate, consistent way to measure tread depth. Precision like that is what safer roads are built on.”

The German Rubber Industry Association (wdk) has released its third-quarter member survey for 2026, indicating a slight easing of anxieties regarding raw material availability. Despite this modest improvement in sentiment, the sector continues to grapple with persistently high costs, with no significant financial respite on the horizon.

wdk Chief Economist Michael Berthel addressed the findings, noting that the acute fears of immediate supply bottlenecks have subsided among member companies. However, he underscored that the overall situation remains highly unpredictable, particularly given the ongoing geopolitical tensions near the Strait of Hormuz, which continue to threaten global trade routes.

While the supply of necessary materials is currently stable, the wdk raw material index for a standard natural rubber compound has surged to its highest point in roughly two years. Berthel pointed out that this disconnect between secure supply and unrelenting price levels leaves firms facing a dual challenge, especially in Germany, where elevated energy costs compound the financial strain of expensive inputs.

The association’s report also reveals a bifurcated business climate, with robust international operations contrasting sharply with weak domestic orders. Berthel characterised the overall recovery as fragile, stressing that without substantial government action to reduce energy levies and bureaucratic hurdles, a genuine upturn for the domestic industry remains elusive.

Hankook Tire, the exclusive tyre supplier for the ABB FIA Formula E World Championship, is set to equip all teams for a historic first in Japan. The 2026 TDK Tokyo E-Prix will mark the series' debut night races, with Rounds 14 and 15 of Season 12 scheduled to start at 20:00 local time on 25 and 26 July.

Tokyo’s presence on the Formula E calendar began in 2024 with the city’s inaugural FIA World Championship race, and it returned as a double-header in 2025. The temporary 2.575-kilometre Ariake waterfront circuit, featuring 18 corners and a mix of straights, technical sections and high-speed combinations, will host the event. Demonstrating a commitment to sustainability, the entire race weekend, including the floodlighting, will be powered by advanced biofuels in partnership with the Tokyo Metropolitan Government.

The unprecedented evening timetable presents a strategic challenge for competing teams. With practice and qualifying occurring during the warmer afternoon, the races will unfold after sunset on a significantly cooler track. This shift demands that engineers not only collect effective data in daylight but also accurately predict tyre behaviour, grip and track temperature evolution as conditions cool towards race time.

Despite the evening start, Tokyo’s intense late-July heat and humidity are expected to persist, placing a premium on the Hankook iON Race tyre’s warm-up characteristics, stable grip and consistent performance. Throughout the weekend, Hankook will also host a booth in the Fan Village, allowing attendees to explore the company’s iON tyre technology and electric vehicle tyre lineup.
