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)

New Bridgestone Underground Mining Tyres Cut Downtime And Boost Load Capacity

New Bridgestone Underground Mining Tyres Cut Downtime And Boost Load Capacity

Bridgestone has launched a new range of underground mining tyres engineered to perform in extremely harsh conditions, enabling greater productivity with fewer resources. The VMNT, VMDL and VMMS products are specifically designed for underground applications, where abrasive rock, high moisture and continuous operations create one of the toughest environments for tyres.

All three models debut Bridgestone’s Subterranean technology, allowing haulers to carry heavier loads without raising inflation pressure. This innovation also lowers the risk of cuts, penetrations and costly downtime. The tyres form part of the company’s Moving More with Less philosophy, balancing higher capacity, durability and safety to help operators maximise output underground.

The tyres reduce penetrations by enveloping rocks instead of allowing them to cut into the rubber while preserving grip and operator comfort. The VMNT offers extended wear life for underground haulers, the VMDL uses a unique lug pattern for traction on load and haul dump machines and the VMMS features a smooth grooveless design where traction comes from terrain contact, plus cut-resistant sidewalls. Available sizes include 26.5 R25, 29.5 R29 and 35/65 R33.

This release strengthens Bridgestone’s off-road tyre portfolio and reinforces its commitment to innovative solutions that improve productivity, durability and safety in specialised global applications.

Rob Cole, Key Account Manager – Off Road Tyres, UK and Ireland, Bridgestone, said, “These tyres are specifically designed for the harshest terrains that you’ll ever come across. Underground mines are among the most demanding and challenging environments imaginable. The beauty of these tyres is that they can carry 15 percent extra load capacity without increasing the pressure. Traditionally, the thinking in this sector was to make the casing stronger and simply put more air into the tyre to carry more load. In reality, that can be counterproductive in these conditions.

“If a tyre fails underground, it can fail with a tremendous amount of force, costing operators huge amounts of money in downtime and, more importantly, potentially endangering life. The machines themselves are getting heavier, so the tyre beads have also been strengthened to help carry more load safely and effectively. What Bridgestone has developed here is a tyre range capable of handling the severe realities of underground mining while helping operators move more with less.”

YOKOHAMA ADVAN Tyres Power TOYOTA 86 To JR2 Class Victory At 2026 WRC FORUM8 Rally Japan

YOKOHAMA ADVAN Tyres Power TOYOTA 86 To JR2 Class Victory At 2026 WRC FORUM8 Rally Japan

The Yokohama Rubber Co., Ltd. has confirmed that its flagship ADVAN brand tyres powered the JR2 Class victor at 2026 WRC FORUM8 Rally Japan, the seventh round of the FIA World Rally Championship. The race took place from 28 to 31 May on courses spanning Japan’s Aichi and Gifu prefectures.

The ADVAN A051T tarmac rally tyres delivered the grip, control and wear resistance essential for navigating the event’s technically demanding stages under high surface temperatures. The JR2 Class is designated for national and regional rally vehicles with engine displacements above 1600 cc and up to 2500 cc. The winning car was a TOYOTA 86 fielded by K-ONE RACING TEAM, driven by Yuta Yamamoto and Shizuka Takehara.

Their well-coordinated, precision driving, combined with the ADVAN A051T tyres’ performance, allowed them to clock the fastest time on every stage except SS10, where a Notional Time was applied. The pair finished over 17 minutes ahead of the second-place car. Yamamoto has now claimed first place in the JR2 Class at Rally Japan for five consecutive years, with ADVAN tyres contributing each time.

Beyond Rally Japan, Yamamoto also competes in the Japanese Rally Championship, where he has secured the JN-3 class series title for three straight years, again supported by ADVAN rally tyres. Rally Japan is the country’s round of the WRC, which ranks alongside Formula 1 and the FIA World Endurance Championship as a premier global motorsport series. The competition is run entirely on tarmac roads, and this year’s WRC calendar features 14 rounds across different nations worldwide.

Tyres Europe Urges Maintained EUDR Timeline With Targeted Technical Fixes

Tyres Europe Urges Maintained EUDR Timeline With Targeted Technical Fixes

Tyres Europe has responded to the European Commission’s recent policy package on the EU Deforestation Regulation (EUDR), offering qualified support for measures that reduce red tape. Industry representatives have pointed to proposed exemptions for retreaded and test tyres as a positive step, arguing these products do not present the same supply chain traceability risks as standard new tyres. The move is seen as a way to prevent unnecessary administrative costs for businesses.

A significant point of clarity within the Commission’s documents involves the dual legal status of tyre makers. Under the new framework, manufacturers are considered operators when importing natural rubber but become first downstream operators when selling finished goods. Tyres Europe has endorsed this distinction, stating it prevents the needless circulation of due diligence statement numbers after the raw material has already been cleared at the border. The association believes the same rationale should apply to imported finished tyres, which have already satisfied verification requirements upon entry.

Nevertheless, serious practical hurdles remain, particularly concerning the EUDR’s digital infrastructure. The tyre sector routinely mixes domestically produced and imported tyres within the same warehouses for extended periods, forcing companies to repeatedly consolidate large volumes of due diligence references for customer shipments. Although the Commission has acknowledged the necessity of grouping tools, the current design of the Information System may undermine these simplified procedures. Industry leaders warn that without technically sound solutions, system resilience could be compromised.

Tyres Europe has formally requested that the EUDR’s existing implementation deadline stay unchanged. Instead of delaying the rules, the group urges policymakers to resolve unresolved operational issues through narrowly tailored fixes. The ultimate goal is to prevent duplicate transmission obligations wherever prior due diligence can be clearly demonstrated, ensuring that supply chains remain functional without sacrificing regulatory oversight.

Adam McCarthy, Secretary General, Tyres Europe, said, “The tyre industry supports the objectives of the EUDR and is ready to implement it. After years of preparation, companies now need implementation certainty. The priority now should be to ensure that the remaining operational issues are addressed through targeted refinements and further implementation guidance, rather than through any reopening of the Regulation itself.”
