TIRED OF POOR TYRE KNOWLEDGE

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)

Pirelli All Set For Singapore Grand Prix

Pirelli All Set For Singapore Grand Prix

Pirelli has confirmed it will bring the same tyre allocation used last year to the Singapore Grand Prix, as Formula 1 remains in Asia for a weekend that also hosts the season's final Sprint and concludes a long triple-header that started in Baku. The Marina Bay circuit, one of the most physically demanding venues for drivers, will again feature the C3 as Hard, the C4 as Medium and the C5 as Soft.

The 4.940-kilometre street circuit is characterised by barriers close to the racing line and limited overtaking opportunities. Changes made to the third sector in 2023 increased the number of high-speed sections, making the lap smoother and faster than before. Although some straights are present, the track remains defined by numerous braking and traction phases across its 19 corners, allowing modern power units to recover energy throughout the lap.

Marina Bay has a medium-to-high level of surface roughness for a street circuit. Since no resurfacing has taken place, values are expected to be broadly in line with last season, if not slightly higher. Track evolution will be significant over the weekend, while intermittent rainfall typical of the equatorial climate can influence grip levels and alter conditions from one session to the next.

The race is held at night, with track temperatures between 30 and 35 °C. Under these conditions, tyres tend to operate within their working window without particular overheating concerns. Mechanical stress is not especially high, and expected degradation will mainly be linked to the normal performance drop-off of the rear axle during traction phases. Graining and wear are also not expected to become limiting factors in race management.

Strategically, Singapore remains one of the races where a one-stop strategy is the preferred option, also considering time lost in the pit lane and the frequent likelihood of neutralisations. While Hard and Medium are again expected to be the reference compounds for the race, the Soft could receive greater consideration on Sunday from more than one team. The softest compound has shown at Budapest, Monza and Baku that it allows drivers to maintain a strong pace thanks to limited degradation, while offering an advantage in grip and confidence. These characteristics could prove even more valuable at a circuit known for significant track evolution.

Latest-generation cars also appear to make better use of softer compounds, allowing the softer end of the range to be used for longer and more competitive stints than in the past. It would therefore come as no surprise to see the red-sidewalled tyre used in Saturday's Sprint or more extensive C5 use throughout the weekend. Medium and Soft were chosen for the opening part of the race, with 14 drivers starting on the C4 and the remainder on the C5, while the Hard was ruled out because the track was still damp after earlier rain. The C3 then became the preferred compound for the second stint, and almost the entire grid completed a one-stop race, with only three drivers opting for two stops.

This will be the seventeenth edition of the Singapore Grand Prix, held continuously since 2008 with the only interruption caused by the pandemic in 2020 and 2021. Sebastian Vettel leads drivers with five victories and Lewis Hamilton has four, while Mercedes leads constructors with five wins. The podium cap will feature an orchid-inspired design, celebrated in Singapore for thriving in heat, humidity and heavy rainfall. The special edition Pirelli Podium Cap is produced by Pirelli Design and signed by designer Denis Dekovic.

Tyres Europe Urges Faster, Smarter EU Trade Defence

Tyres Europe Urges Faster, Smarter EU Trade Defence

Tyres Europe has released a position paper urging the European Union to deploy trade defence instruments more strategically and responsively. The paper argues that measures must remain effective after adoption and tackle distortions that shift across countries, companies and value chains.

The bloc's tyre sector relies heavily on capital investment and specialised know-how, supporting more than 70 manufacturing sites, retreading operations included, plus roughly 20 R&D hubs. Of the approximately 398 million tyres fitted across the EU during 2024, close to 40 percent came from outside the Union. Meanwhile, nine European plant closures have been announced over the last two years, putting over 4,400 jobs at risk.

Two recent episodes underscore the gaps. In the passenger car and light truck tyre case involving China, Brussels launched its probe in May 2025, yet definitive duties did not land until 8 July 2026, by which time sourcing had already migrated elsewhere. For truck and bus tyres, the pressure surfaced only after the 2018 measures took hold. China's share of EU27 and UK imports tumbled from 73 percent in 2017 to under 21 percent by 2019, but Thailand and Vietnam together surged from below 3 percent in 2017 to almost 61 percent in the first five months of 2026. Both cases show trade patterns moving faster than Europe's response, whether before or after duties.

The paper presses the European Commission to move sooner, keep measures potent post-adoption and act as one coordinated system. That entails wiring monitoring, industry insight, investigations and enforcement together from the earliest signal, running systematic post-measure tracking and industry dialogue and aligning trade defence with the Foreign Subsidies Regulation, investment screening and procurement. It further recommends starting work now on a supplementary, WTO-compatible answer to systemic distortions.

Kenda Launches K-SERIES RIPPER Tyre For Trail And All-Mountain Riders

Kenda Launches K-SERIES RIPPER Tyre For Trail And All-Mountain Riders

Kenda Tires has introduced the KENDA K-SERIES RIPPER, a new tyre aimed at modern trail and all-mountain riders seeking speed, control and confidence across varied terrain. The model combines an aggressive yet fast-rolling tread design with dual-layer compound technology and a durable Trail Casing, positioning it as a versatile option from hardpack trails to technical descents.

The RIPPER is intended to fill the space between lightweight cross-country and downcountry tyres and heavier enduro offerings. According to Kenda, it addresses demand for a tyre that climbs efficiently, corners predictably and remains reassuring when trails become difficult, giving riders a single do-it-all solution.

Its neutral-void tread pattern is designed to balance rolling efficiency with traction. Large, broad-based knobs support braking performance and cornering stability, while the layout aims to deliver predictable handling as conditions change. A dual-layer compound pairs a high-traction trail compound with a fast-rolling base layer, enhancing grip on loose or technical ground while preserving efficiency and durability.

A robust Trail Casing is said to balance protection, durability and ride quality for aggressive trail riding and modern e-MTB use. An optimised 62 mm casing and tread width, a stable casing profile and optimised mould design contribute to confidence at the limit. Kenda describes the result as a long-lasting, high-mileage tyre combining speed, grip and durability for riders unwilling to choose between efficiency and capability.
