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)

Parcours, a British wheel brand specialising in aerodynamic, wind-tunnel-tested carbon wheelsets for road, gravel and triathlon cycling, has launched the Strade GT, the debut model in its new GT Series. At the heart of this wheelset lies VibraCORE, a technology developed alongside Lineat and Nottingham Trent University. VibraCORE embeds Lineat’s reclaimed aligned carbon fibre material, known as AFFT, directly into the rim’s spoke bed. This structural integration reduces vibration at its source rather than simply damping it after transmission begins.

The principle behind VibraCORE is straightforward: less vibration reaching the rider means less fatigue, allowing for longer, faster rides. Not all vibrations affect the body equally. Certain frequencies are either amplified by the human body or directly contribute to muscle exhaustion. VibraCORE targets these specific ranges, absorbing and dissipating vibrational energy before it travels through the wheelset to the rider. This approach directly addresses the harsh, high-frequency ‘road buzz’ that makes rough roads particularly draining.

In practical testing at standard road tyre pressures, VibraCORE reduces root mean square vibrational energy by an amount equivalent to lowering tyre pressure by roughly 10 to 15 psi. Crucially, this benefit comes without the usual penalties of softer tyres, such as reduced rolling efficiency or compromised handling precision. As a result, the Strade GT delivers a calmer, more controlled ride over long distances while retaining the stiffness, responsiveness and aerodynamic performance expected from a high-end wheelset.

To verify these claims, Parcours partnered again with Nottingham Trent University for controlled real‑world testing across multiple riders and surfaces. Using vibration sensors and frequency domain analysis based on power spectral density, the data showed that rims with VibraCORE reduced vibration energy by 19 to 23 percent compared to identical rims without the technology. This translates directly into a noticeably smoother ride on rough terrain and lower cumulative fatigue over extended rides.

Beyond comfort, the Strade GT represents an evolution of Parcours’ existing Strade platform. Its rim profile is optimised around a 30‑mm tyre, outperforming the previous model by 3.2W at 48 kmph, improving handling stability by 15 percent and achieving a weight of just 1,130g. VibraCORE also enables the use of lightweight Alpina Carbolite carbon spokes. Although sustainability is not the primary goal, the technology incorporates recycled carbon from Lineat’s AFFT process. Parcours is now developing a full circular pathway so that carbon recovered from old wheels, including those from its Crash Replacement Programme, can be reprocessed into VibraCORE components for future wheelsets. In this way, the Strade GT proves that speed and comfort need not be opposing forces.

Continental is celebrating two decades of its Camaçari tyre factory, situated near Salvador in Brazil. This occasion represents a major milestone for the firm’s operations throughout the Americas, as the site has served as a trusted partner across South America since its April 2006 opening. The facility supplies both replacement tyres and original equipment manufacturers with high-grade products for passenger cars and commercial vehicles.

Approximately 136 million tyres have rolled off the line at Camaçari over the last 20 years. Roughly BRL 1.2 billion (approximately EUR 235 million), has been invested there in the past 10 years alone to sharpen competitiveness through better efficiency, product quality and responsiveness to customers. The factory currently provides jobs for around 2,000 people, making it a leading industrial employer locally, with its future success built on team spirit, consistent quality and a strong customer focus.

The site began as a greenfield project in 2004 and was formally inaugurated in April 2006, with the first tyre, a ContiEcoContact 3, produced five months earlier in November 2005. Today, the factory supplies original equipment to major automotive names including General Motors, Volkswagen, Renault, Honda, Fiat and Mercedes‑Benz, proving its dependable and uniform product standards. This same drive for steady improvement supports the plant’s role in Continental’s wider environmental goals.

By constantly tracking energy use and managing it responsibly, the Camaçari plant ensures that all power generated or consumed on site is used as efficiently as possible. The facility relies entirely on LED lighting, which saves more energy than conventional options, and has carried out targeted production upgrades such as better insulation on critical machinery. These efforts have yielded annual energy savings, including a total cut of 10.4 gigawatt‑hours in 2025, equal to about five percent of the plant’s yearly energy consumption.

Shander Basílio, plant manager of the Continental tyre plant in Camaçari, said, "Our 20-year journey in Camaçari is a story of continuous growth, operational excellence and the deep commitment of our people to this region. I would like to sincerely thank all our employees for their outstanding contribution as well as to our customers for their continued trust. Looking ahead, we are dedicated to writing the next chapter of our plant’s success.”

Rodrigo Bonilha, head of Continental Tires South America, said, “I would like to congratulate our manufacturing team in Camaçari on their 20th anniversary. The production facility is a key asset for our business in the region. By manufacturing premium tires locally, we ensure a reliable supply for the Brazilian market while securing valuable local jobs. This ‘in the market, for the market’ approach is fundamental to how we deliver consistent product quality and performance for customers and consumers.”

The Tire Industry Project (TIP) has announced the publication of a scientific study presenting a sophisticated model designed to track how tyre and road wear particles (TRWP) move through land and freshwater environments. Known as the Mass Balance Model, this tool provides a method for predicting particle concentrations within watersheds across different climates and regions, offering high spatial detail on how these particles travel from roadways towards rivers, lakes and estuaries.

Tyre and road wear particles are created unintentionally during normal driving, where tyres meet the road surface. As scientific and regulatory focus on these particles intensifies, reliable models are essential for understanding their environmental pathways. While research is growing, the behaviour of these particles in waterways remains particularly understudied, making this modelling advance especially relevant.

The model draws on global and local datasets and open-source frameworks, including the ERA5 global climate dataset by the Copernicus Climate Change Service and the Wflow catchment hydrology model by Deltares, a research institute. Its accuracy has been confirmed using field measurements from the Seine River basin in France, the Chesapeake Bay basin in the United States and the Yodo River basin in Japan – three very different watersheds. This validation shows the approach works across diverse watershed sizes, climates and stormwater management systems.

Applying the model to these three regions revealed that the share of particles reaching surface waters varies from just 2 percent up to 18 percent, depending on urbanisation, climate, basin size and drainage infrastructure. Importantly, improvements to stormwater systems could cut particle transport to surface waters by as much as half. This refined model builds on earlier work and is now globally applicable, with ongoing development aimed at making it accessible beyond the scientific community.

Nicolas Tissier, Director of Research at TIP, said, “Having a robust, reproducible model for TRWP transport and fate that can be applied worldwide is essential for advancing both scientific understanding and practical solutions. Our role at TIP is to support rigorous, transparent science that helps researchers, policymakers and industry make evidence-based decisions. By making this model open access, we aim to support broader collaboration across the scientific community around TRWP in the environment and to enable the development of more effective mitigation strategies.”
