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)

Michelin reported lower first-quarter revenue after adverse currency movements offset stable underlying sales, while the tyre maker maintained its 2026 guidance amid growing geopolitical and supply chain uncertainty.

Group revenue for the three months to 31March fell 5.4 percent year on year to €6.2bn, compared with €6.5bn a year earlier. Michelin said the decline was entirely due to currency effects, primarily the appreciation of the euro against the US dollar and several other currencies. At constant exchange rates, revenue was stable.

Tire volumes declined 1.4 percent during the quarter, although replacement sales improved, supported by a 3 percent increase in MICHELIN-brand tire volumes. A favourable product mix, particularly in larger premium tires, partly offset weaker original equipment demand.

The Consumer segment recorded revenue of €3.4bn, down 4.4 percent on a reported basis. Michelin said replacement sales of passenger car and light truck tires remained resilient, while original equipment sales continued to be affected by weaker automotive markets, particularly in China. Sales of 18-inch and larger tires represented 69 percent of MICHELIN-brand sales during the quarter.

Revenue in the Transportation segment fell 11.3 percent to €1.4bn, reflecting weaker original equipment demand in North and South America and adverse exchange rates. Replacement sales increased in Europe but remained subdued in North America amid a softer road freight market.

The Specialties segment reported revenue of €1.1bn, down 3.3 percent. Michelin said mining and aircraft tire sales increased during the quarter, while beyond-road activities stabilised despite continued weakness in agricultural original equipment markets.

Polymer Composite Solutions revenue rose 5.1 percent to €326m, supported by the integration of Cooley Group and growth in sealing and coated fabric activities. Michelin said the segment would continue expanding through the integration of Flexitallic in April and the expected consolidation of TexTech later in 2026.

The company said uncertainty linked to the Middle East conflict continued to create risks around global demand, raw material supply and energy costs. Michelin nevertheless maintained its financial outlook for 2026, citing operational resilience, localised production and supply chain integration.

During the quarter, Michelin also completed the acquisitions of Cooley Group and Flexitallic as part of efforts to accelerate the growth of its Polymer Composite Solutions business.

Hankook Tire, the exclusive tyre supplier for the FIA World Rally Championship, has concluded the fifth round of the 2026 season, Rally Islas Canarias, which took place from 23 to 26 April in Spain’s Canary Islands. For the demanding asphalt stages, Hankook provided its specialised Ventus Z215 and Ventus Z210 tarmac rally tyres, engineered to handle extreme conditions.

The event, first held in 1977, marked its 50th anniversary this year and its second edition as an official WRC round. Competitors tackled 18 special stages across Gran Canaria Island, centred around Las Palmas, covering approximately 322.61 kilometres. The course featured rough, high-abrasion volcanic asphalt with dramatic elevation changes, while dense fog and local rain above 1,000 metres made weather a decisive factor. The opening day’s Super Special Stage at the BP Ultimate Circuito Islas Canarias offered side-by-side racing, where small pace differences quickly altered positions.

Hankook’s tyres provided reliable grip and control at high speeds and through continuous cornering, helping drivers maintain stability on the technical routes. Sébastien Ogier of TOYOTA GAZOO Racing secured his first win of the season, leading a team podium sweep. In the Drivers’ Championship, Elfyn Evans leads with 101 points, followed closely by Takamoto Katsuta on 99.

The 2026 WRC season now moves to Round 6, Vodafone Rally de Portugal, from 7 to 10 May in northern Portugal, a demanding event mostly on unpaved surfaces. Hankook will operate a ‘Brand World’ booth in the service park there, using motorsport content and hands-on experiences to promote its premium image. As exclusive WRC tyre supplier since 2025, Hankook continues integrating data from over 70 global championships into R&D, advancing high-performance tyre technology and the Ventus brand’s global leadership.

wdk, the German Rubber Industry Association, and the ADK, the German Rubber Industry Employers’ Association, hosted their annual Rubber Industry Day in Berlin on 28 April 2026. The event saw wdk President Michael Klein issue an urgent call for industrial policy measures, warning that pressure on Germany’s manufacturing base remains relentless. He argued that the country can no longer afford strategic delays, insisting that declarations of intent must be replaced by immediate action to reduce bureaucracy and energy costs for businesses.

Citing fresh member survey data, Klein reported that sales, revenue and production levels in Germany’s rubber industry are predominantly declining compared to the previous year. He described this downturn as a clear warning signal, noting that companies have exhausted their potential at domestic sites. Without political support, he added, only foreign markets remain viable alternatives, while Germany continues to lose industrial substance.

The wdk president stressed that the federal government’s failure to implement countermeasures risks permanent damage to the nation’s industrial base. He expressed bafflement that political decision-makers have long known what needs to be done yet have failed to act for an extended period. Klein concluded that proactive intervention is now essential, as the erosion of Germany as a production location must finally be stopped to preserve the manufacturing sector as the backbone of the economy and a guarantor of prosperity.

Bridgestone Americas has concluded the first phase of a joint research initiative with Penske Transportation Solutions, known as the Decarbonisation Lab, which focused on identifying commercially ready methods for reducing carbon emissions in real-world commercial fleet operations. The partnership confirmed that both companies intend to continue their collaboration with a second phase of testing in 2026, building on the operational data gathered during the initial stage.

Working alongside Dynamon, a specialist in advanced data analytics, the Lab’s first phase involved logging more than 500,000 fleet miles to assess three specific operational areas. The use of low-rolling-resistance retreads, continuous tyre pressure monitoring and Bridgestone casings on Penske vehicles produced a measurable gain of 6.35 percent in fuel economy. In a separate track, the partners tested renewable diesel in Tennessee, a state outside the usual Low Carbon Fuel Standard markets, to study long-term maintenance needs and efficiency results.

A third work stream saw Penske and Bridgestone engineering teams jointly redesign aspects of Bridgestone’s automotive tyre retail distribution network, with the goal of cutting roughly 152,000 miles from that logistics system. Scaling that approach across the entire dedicated fleet operated by the two companies would correspond to a four to six percent drop in CO₂ emissions, according to the project’s projections.

The overall findings from the Decarbonisation Lab reinforce the idea that meaningful near-term sustainability gains require a combination of proven technologies, rigorous data collection and close industry cooperation rather than isolated efforts. Representatives from both organisations are scheduled to present the first-phase results at ACT Expo 2026 in Las Vegas on the afternoon of 4 May.

Erik Seidel, head of sustainability for Bridgestone in the Americas, Europe, Middle East and Africa, said, “Our Bridgestone team is proud to have partnered with Penske for more than a decade, from IndyCar racing to deploying millions of retreaded tyres across the Penske fleet. The Decarbonisation Lab is a testament to how sustainable transformation can be accelerated when we work together.”

Bill Combs, Senior Vice President, Partnership & Sustainability Strategy, Penske, said, “We are honoured to collaborate with Bridgestone to bring the Decarbonisation Lab to the marketplace. Our companies have enjoyed a successful history of uncovering great solutions that benefit our customers and the industry.”
