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?

Remember success does not reward a lack of action. (TT)

Firestone Unveils Pathway AS Tyre, Covering Nearly 77% Of Registered Vehicles

Firestone Unveils Pathway AS Tyre, Covering Nearly 77% Of Registered Vehicles

Firestone, a Bridgestone Americas subsidiary, has introduced the Firestone Pathway AS, an all-season touring tyre built for everyday drivers. It comes in 73 sizes, giving it the widest vehicle coverage of any Firestone tyre, and pairs dependable performance and long tread life with value, all backed by a 65,000-mile limited mileage warranty.

Development was shaped heavily by consumer feedback, which pushed improvements in wet traction, tread life and ride comfort over the predecessor. The original plan called for 48 sizes, but 25 more were added mid-development to broaden market reach, helping Firestone cover nearly 77 percent of registered vehicles.

A tread compound engineered for longevity, additional sipes and an optimised see-through void promote even wear and sustained traction. Deep interlocking 3D sipes deliver grip from light snow to dry and wet pavement. Internal testing recorded wet braking gains of 18 percent against the Uniroyal Laredo HT, 11.7 percent against the Firestone All Season and 7.4 percent against the Toyo Extensa AS2, along with shorter dry braking than six leading rivals. Low rolling resistance also supports fuel efficiency in combustion-engine vehicles.

Nationwide availability is underway, with fitments covering popular models such as the Toyota Camry, Toyota RAV4, Subaru Outback, Jeep Grand Cherokee and Chevrolet Equinox.

Leslie Sawyer, Senior Product Design Engineer, Bridgestone Americas, said, "Most drivers want a tyre they can depend on. The Firestone Pathway AS is designed to deliver reliable performance and long-lasting value, giving drivers the confidence they need in everyday driving situations."

Enviro Signs USD 2 Million Conditional Service Agreement For North American Tyre Pyrolysis Plant

Enviro Signs USD 2 Million Conditional Service Agreement For North American Tyre Pyrolysis Plant

Scandinavian Enviro Systems AB (publ) has entered into a conditional service agreement with an international operator that provides transport services to the energy sector. The agreement follows a letter of intent signed by the two parties on 17 March 2026 and marks a further step towards establishing a tyre pyrolysis plant in North America. Using Enviro’s technology, the facility is intended to recycle up to 50,000 tonnes of end-of-life tyres annually.

Under the terms of the agreement, Enviro will produce the technical documentation needed for the plant’s permit applications and prepare an initial design for the entire facility. For these services, the company will receive a fixed fee of USD 2,000,000, corresponding to approximately SEK 19.5 million. The fee is divided between USD 500,000 for permit application work and USD 1,500,000 for plant design, with USD 450,000 payable once the customer decides to proceed and the remainder paid in instalments as various parts of the services are delivered. Additional work and technical support beyond the fixed-fee scope will be invoiced on an ongoing basis.

The start of Enviro’s work depends on the customer making a final decision to proceed with the project. That decision, in turn, requires the customer to have secured a site for the plant and to have entered into binding agreements with buyers of the plant’s two main products, oil and carbon black, covering at least 75 percent of expected production for each product. Should the customer neither decide to proceed by 31 December 2027 nor elect to continue, the agreement will terminate.

The assignment covers two principal deliverables: technical documentation required for environmental, planning and fire safety permit applications and an initial design of the whole plant, including drawings, equipment lists, calculations and technical specifications. The design will serve as the basis for more detailed engineering work before an investment decision. Enviro will also provide technical support during the permit application process for 12 months after delivering the permit documentation. The agreement does not grant any right to use Enviro’s technology to construct or operate the plant, which would require a separate licence agreement.

According to the timetable, the assignment is expected to be completed about seven months after the customer’s decision to proceed, with permit application documentation ready after roughly five months. The customer may terminate the assignment with 30 days’ notice, in which case Enviro is entitled to compensation for work performed and costs already incurred. Enviro remains entitled to compensation regardless of whether permits are granted or the plant is ultimately built. The agreement is described as an important step in Enviro’s strategy to establish technology-based plants internationally, with the design potentially forming the technical basis for a future licence agreement.

Fredrik Aaben, CEO, Enviro, said, “This is an important step towards establishing Enviro’s technology in North America. Together with the Customer, we are now moving from a letter of intent to a binding conditional agreement, and we look forward to designing the plant as soon as the project is ready to proceed.”
