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?

Pirelli C3 Compound Shines Across Six Days Of 2026 F1 Pre-Season Testing

Pirelli C3 Compound Shines Across Six Days Of 2026 F1 Pre-Season Testing

The concluding day of 2026 F1 Pre-Season Testing at the Bahrain International Circuit saw Charles Leclerc set the overall fastest lap of the entire six-day programme. The Ferrari driver delivered a time of 1:31.992s on the C4 compound Pirelli tyres during the final hour of running, improving by eight-tenths of a second on the previous benchmark established by Kimi Antonelli. This performance placed him ahead of Lando Norris in the McLaren, who recorded a 1:32.871s on the C3 tyre. Max Verstappen and George Russell followed, with times of 1:33.109s and 1:33.197s, respectively, both also set on the C3 compound. Notably, none surpassed Leclerc's own leading time on that particular compound, a 1:32.655s. Pierre Gasly rounded out the top times, utilising the softest C5 tyres to post a 1:33.421s.

The C5 compound saw limited use on the final day, employed only by Alpine and Williams for short-run simulations. Aston Martin, despite having the tyre available, opted not to run it and instead completed just six laps on C3s before their session was curtailed. In contrast, teams focused on different aspects of performance. Gabriel Bortoleto and Arvin Lindblad set the pace on the harder C1 and C2 compounds, respectively. The day was also notable for the absence of several drivers, including Fernando Alonso, Lewis Hamilton and Alex Albon, who did not participate in any track action.

Beyond outright speed, teams dedicated significant effort to long-distance evaluation. Gabriel Bortoleto completed 25 laps on the C2 compound for Audi, while Esteban Ocon undertook 24 laps on C1s for Haas. Ocon was also the sole driver to run intermediate tyres, completing four laps to assess front wing behaviour. Over the entire six-day test, a total of 41,366 kilometres were covered across all 11 teams, a distance exceeding the Earth's circumference. The C3 compound proved the most popular, accounting for 61 percent of all laps. In total, 591 sets of slick tyres were utilised throughout the pre-season, with 326 of those deployed in the final three days alone.

Mario Isola, Pirelli’s Motorsport Director, said, “The radical changes introduced to the cars have inevitably shifted the teams’ focus towards power units and aerodynamics rather than tyres over the last few days. The final stages of testing are usually dedicated to optimising the car-tyre package, but it is clear some teams haven’t reached that point yet. Generally speaking, track feedback has been consistent with our simulation expectations. Drivers were able to gain confidence with the entire Pirelli range through both performance trials and long runs, even using the C4 and C5 compounds which aren’t particularly suited to a circuit like Sakhir.

“Mechanical resistance appeared strong across all options, with no signs of graining or blistering. Degradation levels are almost certainly higher now than what we expect for the Bahrain race, when temperatures will be lower and cars more developed. A central theme this season will certainly be balancing temperatures between the axles, especially ahead of the first race in Melbourne. The lower loads of a street circuit might require more intensive tyre preparation or differentiated tyre blanket temperatures, particularly in qualifying. In any case, it will be interesting to discover in Australia how much teams have been ‘sandbagging’ their engine power to avoid showing their hand. We only have to wait a couple of weeks to see the true pecking order.”

Radar Tires Expands Renegade-X Line With Nine New Sizes, Including First 26-Inch Fitments

Radar Tires, a globally recognised manufacturer known for its off-road and high-performance products, is broadening its footprint in the light truck and off-road vehicle segment with a major expansion of its popular Radar Renegade-X line. Responding directly to robust market demand and the model's sustained success among enthusiasts, the company will introduce nine new sizes featuring rim diameters from 18 to 26 inches. A key highlight of this expansion is the debut of 26-inch options, catering to the growing trend of customised and lifted trucks requiring larger wheel fitments.

Since its market introduction, the Renegade-X has built a strong reputation for delivering uncompromising off-road capability without sacrificing on-road civility. Consumer feedback consistently praises its superior traction in mud and rocky terrain, its robust durability and notably low road noise – a combination rarely achieved in the mud-terrain category. This balance of aggressive performance and refined driveability has solidified its appeal.

The tyre’s distinctive design is the result of a collaboration with the renowned Italian design house GFG Style, blending engineering rigor with premium aesthetics. Its technical features include a high void-to-lug ratio designed for effective self-cleaning in mud, alongside a specialised rock-crawl compound for enhanced grip on varied surfaces. Durability is addressed through a three-ply sidewall construction, while a strategic combination of stone ejectors and serrations protects the tyre casing. Furthermore, sidewall lugs inspired by stealth design not only contribute to a striking visual profile but also improve lateral traction in challenging conditions.

The newly added sizes are intended for a wide range of vehicles, including Jeeps, pickup trucks and full-size SUVs. Availability is scheduled to commence through authorised dealers in February 2026, with additional sizes arriving through April of that year.

Rob Montasser, Vice President, Radar Tires, said, “The response to the Radar Renegade-X has exceeded our expectations, and our dealer partners have consistently requested additional sizes to meet customer demand. This nine-size expansion, including our first 26-inch rim diameter sizes, demonstrates our commitment to providing dealers with a comprehensive product offering that supports sustained, profitable growth while giving consumers more choices for their vehicles.”

Nokian Tyres Publishes Climate Transition Plan

Nokian Tyres Publishes Climate Transition Plan

Nokian Tyres has formally released its climate transition plan, a comprehensive roadmap guiding the company’s decarbonisation efforts. This strategy is anchored in the company’s near- and long-term climate objectives, which received validation from the Science Based Targets initiative in 2024. Crucially, the organisation’s ambition to achieve net-zero emissions across Scope 1, 2 and 3 aligns with the stringent requirements of limiting global warming to 1.5°C, as dictated by contemporary climate science.

The company has already made significant progress, particularly within its own operations. By the close of 2025, Nokian Tyres had successfully reduced absolute Scope 1 and 2 emissions by more than 38 percent relative to the 2022 baseline, edging closer to its interim target of a 42 percent reduction by 2030. The newly published plan elaborates on this trajectory, detailing the primary sources of emissions and the essential strategies for reduction both internally and across the broader value chain. These actions are designed to meet the 2030 benchmarks while maintaining a clear pathway towards the ultimate goal of net-zero greenhouse gas emissions by 2050.

Endorsed by the company’s Board of Directors, the plan is a living document subject to updates as emission-reduction technologies and methodologies evolve. Further details are accessible on the corporate website. This strategic approach is already yielding tangible results and external recognition. The company’s Romanian facility stands as the world’s first full-scale tyre factory to achieve zero CO2 emissions in its own operations. Furthermore, this commitment to sustainability was acknowledged in 2025 by TIME Magazine, which named Nokian Tyres one of the World’s Most Sustainable Companies, and by CDP, which awarded the firm its sixth consecutive leadership-level score for climate action.

Paolo Pompei, President and CEO, Nokian Tyres, said, “Our work towards net-zero emissions is not only about us but also about drivers worldwide. Through our actions and innovations, we reduce the environmental impact of tyre manufacturing while delivering the safety and quality that define Nokian Tyres.”
