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)

Giti Tire has characterised the upcoming Euro 7 emissions framework as a validation of its existing research trajectory rather than a disruptive regulatory hurdle. Historically, tyre assessments have centred on criteria such as vehicular handling, tread life and fuel economy. The updated European standards introduce a novel parameter by capping particulate matter generated from tyre degradation, thereby acknowledging this source as a major contributor to roadside pollution.

The Singaporean manufacturer, drawing upon more than seven decades of technical experience, has maintained that optimal tyre design necessitates a holistic approach. Engineering teams at the company have long prioritised the synchronisation of tread geometry, rubber chemistry and production accuracy to achieve equilibrium between conflicting demands. Present-day products are expected to deliver secure wet-weather traction, energy-saving rolling resistance, passenger comfort and sustained endurance, all while curtailing material loss over the product's usable life.

Giti’s role as an original equipment partner to global vehicle producers, including German and Chinese automotive leaders, has provided practical insight into the rigorous specifications of contemporary mobility. The company perceives the harmonised testing protocols under Euro 7 as a constructive force that stimulates technological advancement across the supply chain. By establishing clear abrasion thresholds, the legislation motivates engineers to pursue solutions that diminish ecological footprints without sacrificing the protective and responsive qualities that motorists rely upon.

Ongoing internal programmes at Giti are concentrating on next-generation elastomer blends, refined surface patterning, friction reduction for improved efficiency, extended product durability and tighter quality controls during fabrication. These developmental efforts are intended to concurrently address environmental concerns and consumer performance expectations. As the regulatory landscape evolves, the firm remains dedicated to fundamental research that supports sustainable transportation, viewing the Euro 7 mandate as a progressive milestone that reinforces its commitment to future-ready tyre engineering.

Pirelli has designated the SC0 rear tyre as the new benchmark for Moto2 as the MotoGP World Championship resumes its season this weekend at Silverstone for the 12th round. The Italian manufacturer is supplying its standard range compounds for both support classes, with the updated SC0 making a notable return to the British circuit following its successful evaluation there last year.

The 2026-spec soft rear tyre, which initially debuted as a development prototype, features an altered structure from its predecessor and was universally embraced by competitors during practice sessions, even contributing to a new lap record. Its promotion to the standard lineup sees it joined at the rear by the new medium SC1 compound, formerly a development specification, while front tyre duties are covered by the soft SC1 and the medium SC2 options.

Silverstone presents a formidable technical challenge as the longest venue on the calendar at 5.9 kilometres, demanding exceptional machine and rider performance through high-speed corners and rapid directional shifts. The circuit’s low-abrasion surface and notably wide racing corridor allow for varied lines, adding another layer of strategic complexity to the already fast-paced weekend.

In the Moto3 class, Pirelli has made available the soft SC1 and medium SC2 compounds for both front and rear positions. The majority of the field last year favoured the medium SC2 at both ends, a choice that propelled José Antonio Rueda to victory from the back of the grid, though a segment of riders alternatively selected the softer SC1 option for their machines.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “For this weekend's round at Silverstone, one of the most iconic and technically demanding circuits on the World Championship calendar, Pirelli will once again provide standard range tyres for both classes, featuring the rear soft SC0 compound that made its Moto2™ debut at this very circuit last year as the E0125 development option. The E0125, which complemented the then standard soft tyre, was immediately appreciated by the intermediate class riders, who, on a highly demanding circuit characterised by numerous high-speed corners and changes of direction where stability is essential, focused exclusively on this new solution from Friday onwards.

“Introduced again at subsequent events, the former E0125 quickly became the Moto2™ riders' benchmark, offering greater stability, outright one-lap performance and consistent performance across a wide variety of weather and track conditions. As a result, it was promoted to the new standard soft tyre for this season. More than a year after its debut, and thanks to the significant development work carried out by the teams during this period, the SC0 has already contributed to numerous lap records this season. Weather conditions permitting, it will therefore be interesting to see whether Silverstone can deliver further progress compared with last year's benchmark.”
