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 introduced the Winter i*cept evo 4, a new addition to its Alpine winter lineup. The studless tyre is designed for passenger cars and SUVs, targeting enhanced winter safety and fuel efficiency. It replaces the previous generation with a 5 percent improvement in snow grip, achieved through wider lateral grooves and semi-sipe technology. The next-generation model builds on Hankook's proven Alpine winter engineering, refining traction, braking, efficiency and tyre longevity even in the harshest winter conditions.

The tyre offers balanced grip compounds and hydroplaning resistance for wet braking, while an optimised curing process and balanced wear design extend mileage and fuel efficiency. A tread design focused on noise reduction provides a quieter, more comfortable ride by minimising road and impact noise caused by sudden braking and steering. All Hankook winter tyres carry the 3 Peak Mountain Snowflake rating for severe snow service standards.

The evo 4 joins a broader winter portfolio that includes the studless Winter icept iZ3 for passenger cars and iZ3 X for SUVs and crossovers. Studded options include the Winter i*Pike RS2 for passenger cars, including sedans, coupes, hatchback, and some smaller crossovers depending on tyre size, and the i*Pike X for SUVs, crossovers and light trucks. The new tyre is backed by the SureTire Plan with a 30,000-mile treadwear warranty, a 30-day free trial, a limited warranty and road hazard protection, subject to applicable terms and conditions.

Dealers can now order the Winter i*cept evo 4 in 37 SKUs and the SUV version in 45 SKUs. Consumer availability is expected later this fall.

K C Jensen, Vice President of PC/LT Sales, said, “Drivers need tyres that provide dependable control throughout the winter season. The Winter i*cept evo 4 combines stronger snow traction, enhanced wet braking and improved efficiency to help drivers navigate changing winter road conditions with confidence.”

The AZuR network has welcomed North Rhine-Westphalia’s first circular economy strategy, viewing the explicit inclusion of used tyres as confirmation of its longstanding engagement. The strategy aims to move the state from linear value chains towards a circular economy and strengthen its position as a leading European location for such practices, with priority areas spanning circular construction, chemicals, technology, circular cities and a high-performing secondary raw materials sector.

Used tyres occupy a dedicated page within the strategy, granting political visibility to a material flow that already requires integrated approaches. These range from extending the service life of suitable tyres through repair and retreading to recovering secondary raw materials via mechanical and chemical recycling alongside complementary processes. The document identifies used tyres as a significant material flow in the state and highlights steel and rubber recovery as well as retreading.

The state government has signalled its intention to expand circular approaches to tyre reuse and recycling, expressly incorporating public procurement and the vehicle fleets of public companies. This reflects a core principle of the tyre circular economy, whereby suitable tyres should remain in use as long as possible, with repair, retreading and regrooving extending service life before mechanical and chemical recycling recover industrially reusable materials.

AZuR is paying particular attention to the political focus on retreading. The strategy notes that retreading is established for commercial vehicle tyres while passenger car retreading has declined, and the state government declares its intention to support retreading projects and further recycling processes. For the network, the inclusion of used tyres creates a starting point for linking the entire tyre circular economy with raw material security, secondary raw material markets, public procurement and industrial competitiveness.

AZuR maintains close contact with the relevant state ministries, contributing the experience and solutions of its network partners across the entire tyre value chain. It will continue this exchange and feed practical experience into implementation of the strategy, with the goal of keeping tyres and their contained raw materials in circulation for as long as economically viable.

Goodyear takes centre stage at Silverstone this weekend as title sponsor of the Goodyear 4 Hours of Silverstone, the second consecutive year it has headlined the European Le Mans Series event following its return to the calendar last year after a six-year break.

The manufacturer will equip 37 cars across LMGT3, LMP2 and LMP2 Pro/Am with its Racing Eagle tyres. LMGT3 entrants will use the Medium compound, chosen for its adaptability across varying conditions and driving styles, while LMP2 and LMP2 Pro/Am crews run their own Medium specification, a staple of the series since debuting at Le Castellet last season. Wet-weather Racing Eagle tyres remain available should conditions demand.

Silverstone's fast nature is set to shape tactics, with fuel consumption a likely determinant of pit-stop windows. Goodyear anticipates LMGT3 outfits will favour single-stinting to maximise pace on fresh rubber at every stop, whereas LMP2 and LMP2 Pro/Am squads could split between single and double-stinting approaches.

Off-track, Goodyear has arranged several activations. Vector Sport's #10 car ran a special Goodyear Racing livery last weekend at Caffeine & Machine's Warwickshire venue and will race in the same colours. The company also backs Friday's ELMS Charity Run, where Racing Eagle tyre stacks will mark each kilometre and runners finish beneath an inflatable Goodyear arch, with proceeds going to the Luca Guintoli Foundation, supporting families affected by childhood cancer. Goodyear Racing Eagle tyres additionally feature in NASCAR action at World Wide Technology Raceway in Madison, Illinois.

Stephen Bickley, Goodyear Endurance Program Manager, said, “Silverstone should be a fairly straightforward race from a tyre strategy perspective. The high-speed nature of the circuit means fuel consumption will be high, so fuel strategy is likely to be the main factor influencing pit stop timing. The tyre allocations broadly give teams the flexibility to change tyres at every stop, so there is less of a need to stretch a set of tyres purely to save time in a pit stop. We therefore expect teams across both categories to largely focus on single-stinting tyres. The biggest variable at Silverstone is always the weather, which can quickly change stint lengths and pit stop timing.”
