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)

Hankook Tire has seen its summer tyre range validated this spring by three independent testing authorities. In the Auto Bild summer tyre test from the 10/2026 issue, the Ventus evo claimed overall victory in the 245/45 R19 size with a score of 1.1 and an ‘Exemplary’ rating, while the same model also won the Auto Bild allrad summer tyre test in the 255/45 R19 size from the 12/2026 issue, achieving a 1.2 score. Meanwhile, the Ventus Prime 4 earned strong praise in the AvD summer tyre test.

The Ventus evo’s success in the Auto Bild test began in qualification, where it secured a spot among 20 finalists from a field of 50, thanks in part to the second-best braking distances recorded. In the final dry handling assessments, it delivered the shortest braking distance and the highest average handling speed, while on wet surfaces it posted the fastest lap time on the aquaplaning circuit and the quickest speed in wet handling. The tyre also offered the best price-to-mileage ratio among all finalists.

In the separate Auto Bild allrad test, conducted in a size common for modern SUVs, the Ventus evo demonstrated strength both on and off the road. It led the field in wet braking and wet handling, achieved the highest traction on gravel and wet grass, and remained competitive on dry surfaces with low noise levels and short stopping distances. The test jury concluded it was the most convincing all-rounder for all-wheel-drive SUVs.

In the AvD summer tyre test, conducted with test specialist Tempotire in the 215/55 R17 size, the Ventus Prime 4 delivered a ‘Very good’ overall result. Its performance was particularly notable in wet conditions, where it recorded fast lap times, balanced handling and short braking distances while providing clear steering feedback and safe aquaplaning reserves. On dry roads, it offered reliable handling and strong rolling comfort. The tyre also earned high marks for sustainability, with production in Europe ensuring short transport routes and its EU label ratings reflecting modern construction. The jury highlighted its durability and cost efficiency, reinforcing Hankook’s reputation for delivering premium quality at a competitive price.

AZuR partner NEW LIFE initiative is set to host the inaugural Municipal Climate Dialogue on 22 April 2026, coinciding with International Earth Day. This free online forum, beginning at 10:00 a.m., is designed for municipal decision-makers to connect with experts and editors from the trade journal KOMMUNALWIRTSCHAFT. The event is structured around three focused 30-minute sessions, each dedicated to exploring proven strategies and concrete implementation methods for developing urban spaces that are both liveable and climate-friendly.

A central theme of this digital expert discussion is the critical role of sustainable building materials, with particular prominence given to high-quality recycled products derived from tyre rubber granulate. These solutions directly address the objectives of a climate-resilient city: reducing CO₂ emissions, minimising waste and conserving natural resources. Furthermore, the use of tyre rubber granulate obtained from end-of-life tyres aligns with the German Circular Economy Act (KrWG), which mandates public contracting authorities to prioritise recycled and durable materials. The dialogue will highlight how such products are instrumental in sustainable urban development.

Following a brief opening plenary, the event will feature three parallel 30-minute sessions, allowing participants to easily navigate between online rooms dedicated to distinct urban development topics. The morning begins at 10:10 a.m. with a focus on sustainable urban development, covering building protection through green roofs and photovoltaic systems, impact sound insulation for various construction types and vibration isolation. At 10:40 a.m., the discussion shifts to playgrounds, sports facilities and green spaces, addressing impact-absorbing flooring, playing field surfaces and green area reinforcement. The final session at 11:10 a.m. centres on transport and sustainable mobility, exploring traffic noise protection, recycled rubber asphalt for roads and traffic calming measures.

Products made from tyre rubber granulate offer municipalities a combination of ecological and economic advantages. Their use helps reactivate open spaces and reduce surface sealing, improving the urban climate through applications like water-permeable paving and rainwater-retaining green roof layers. These solutions are weather-resistant, slip-resistant and customisable while also providing long-term economic benefits due to their durability, low maintenance requirements and reduced need for repairs. Such high-quality recycled products are already being successfully implemented in urban development and municipal renovation projects nationwide.
