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)

American tyre brand General Tire has released a new all-season tyre aimed at drivers who refuse to compromise between on-road precision and off-road toughness. The Grabber Cross A/S achieves this balance by marrying an unusually stiff tread pattern with a rubber mix explicitly formulated to resist cutting and chunking on harsh terrain.

For drivers who spend time on rocky or uneven terrain, the tyre’s hexagonal tread blocks deliver grip through sharp biting edges, while chamfered groove edges further boost off-road traction. A highly resistant crossover compound protects against tread damage on rough ground. Meanwhile, transverse and longitudinal sipes carved into the blocks provide wet and snowy road grip, and an open shoulder design rapidly channels water away to prevent aquaplaning. On dry roads, internal support elements between the blocks create an extra-stiff tread that distributes pressure evenly, allowing precise steering and sustained high-speed running without sacrificing mileage. Importantly, that stiffness does not come at the cost of comfort, as the tyre also delivers low rolling noise and a smooth ride.

Certified for winter use, the Grabber Cross A/S carries both the M+S marking and the three-peak mountain snowflake symbol, the latter being mandatory in Germany and France since 2024. General Tire offers the model in 44 sizes spanning 16 to 22 inches in diameter, with top speed approvals reaching 240 kmph depending on the size. The tyre fits a broad range of two- and four-wheel-drive vehicles, including popular SUVs such as the VW Tiguan, KIA Sorento, Ford Kuga, Mazda CX 90 and Volvo XC90. An ‘EV Compatible’ sidewall logo also confirms its readiness for electric vehicles.

The Grabber Cross A/S is now reaching dealer shelves and service centres. According to the EU tyre label, this all-season 4x4 tyre earns a rolling resistance rating of C or D, a wet grip score of C and a B classification for rolling noise – positioning it as a versatile option for SUV and EV owners who want one tyre for all seasons.

Matthias Bartz, Business Development Manager for General Tire in Europe, the Middle East and Africa, said, "The Grabber Cross A/S is General Tire's entry into a new product segment. The tyre is designed for high speeds on fast roads but also offers excellent off-road performance in challenging terrain. With our extensive size portfolio, we can offer tyres for about 85 percent of the most popular crossover SUVs.”

Portronics has launched a compact portable tyre inflator named the Vayu Nano, designed specifically to address the space constraints faced by bicycle and motorcycle commuters. Weighing just 185 grammes, the device easily fits into a jacket pocket, small bag or scooter storage compartment. Its matte-black finish and short 7.5-centimetre air hose make it suitable for two-wheelers and minor pressure top-ups rather than inflating car tyres from scratch.

The Vayu Nano delivers up to 120 PSI, sufficient for motorcycles requiring around 45 PSI, bicycles needing approximately 35 PSI and standard sports balls. It can fill a tyre from zero to 35 PSI in under five minutes. A digital display shows pressure in PSI or BAR alongside a battery indicator, while preset modes for various inflatables and a manual custom setting are included. An auto shut-off function stops the device once the target pressure is reached to prevent over-inflation.

Power comes from a dual 600 mAh battery setup with USB-C charging, allowing use with existing phone chargers or power banks. A built-in LED light features an SOS mode for low-light conditions. Priced at INR 4,999, the Vayu Nano is available at a launch price of INR 2,999. It comes with a 12-month warranty and can be purchased through the company’s website or at ecommerce websites and standard offline stores.
