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)

Liberty Tire Recycling has published the industry’s first US company-commissioned lifecycle assessment (LCA) centred on rubber-modified asphalt solutions made from recycled tyres. The study was commissioned by Liberty and carried out by Boundless, applying internationally recognised LCA methodology to evaluate the environmental impacts of the company’s asphalt-related products against conventional alternatives used in asphalt modification.

The company described the assessment as a notable step forward for rubber-modified asphalt. Environmental gains are routinely linked to recycled tyre materials in road building, yet Liberty said this analysis supplies quantified evidence behind such assertions. Greenhouse gas emissions tied to its rubber-modified asphalt solutions were tracked throughout their lifecycle.

Results showed that Liberty's asphalt products carried substantially lower greenhouse gas impacts than conventional SBS polymer modifiers. Recovering and reusing end-of-life tyre materials was also found to deliver environmental benefits exceeding the impacts of processing them. Liberty said the findings give transportation agencies, engineers, contractors and infrastructure stakeholders data-driven insights for choosing materials.

Four products were assessed: crumb rubber and three asphalt additives, namely dry mix rubber additives, a DOT additive and combined micronised rubber powder with the Rheopave additive. Dry mix rubber additives yielded the largest carbon benefit, avoiding up to 0.577 kg CO₂e per pound produced, while the tyre-derived products achieved over 100 percent lower greenhouse gas footprint than traditional SBS modifiers. Each product assessed generated a net environmental benefit, with reductions spanning 0.47 to 0.57 kg of CO₂e per pound.

Liberty said the study helps set a benchmark for measuring and communicating environmental impacts as sustainability gains prominence in infrastructure projects, and that transparent, science-based data will matter increasingly to public agencies and industry leaders weighing performance and environmental goals.

The all-new Vredestein Quatrac Pro 2 premium ultra-high-performance all-season tyre has had its class-leading capabilities confirmed through independent testing in Spain and Finland. The tyre established new benchmarks for wet braking and recorded the fastest snow handling lap times against four leading all-season rivals.

Testing in Finland at the UTAC winter facility used a sensor-equipped BMW 5 Series to measure speed and lap times, with all tyres subjected to identical procedures. The Quatrac Pro 2 achieved the quickest snow handling lap, showing exceptional grip, balance and controllability, which testers praised for excellent response and stability in all circumstances. Its snow performance is aided by 3D interlocking sipes at the shoulder, whose zig-zagged inner faces in horizontal and vertical planes limit tread block movement.

In Spain, Applus+ IDIADA assessed dry and wet handling and braking on certified asphalt with defined water depth. The tyre outperformed key competitors in wet conditions, delivering a 7 percent wet-braking advantage over one long-established segment rival, and separate testing confirmed an A wet-grip rating across the entire size range, unique in the UHP all-season segment. Four longitudinal grooves in every size, also unique in the category, plus directional lateral grooves, support water evacuation and aquaplaning resistance.

Compared with its predecessor, abrasion resistance has improved by 8 percent to maximise tyre life, while rolling resistance is reduced by 10 percent to boost driving range, underlining suitability for electric vehicles. The Quatrac Pro 2 is available now for wheel diameters from 17 to 24 inches, with section widths up to 355 mm for powerful passenger vehicles.

Daniele Lorenzetti, Chief Technology Officer, Apollo Tyres Ltd, said, “Vredestein has long been recognised for its premium all-season tyres, and these independent tests reinforce that reputation. The Quatrac Pro 2 delivered exceptional grip and traction against other premium competitors while also improving efficiency and longevity compared with its predecessor.”
