The huge volume of data that can be collected from tyres is beyond most people’s comprehension, especially when most don’t even know they should be checking the tyre inflation pressures on a regular basis.

Tyre technology is advancing at an ever increasing rate. The demands of consumers on the products our industry produce are changing as vehicles evolve. The advent of electric vehicles (EV) has placed a series of demands on tyres that have not been previously experienced.

How will hydrogen-powered vehicles (HPV) vary from the EV requirements is an answer yet to be found. The intrusion of artificial intelligence (AI) into daily life is permeating faster than most can appreciate, and tyres are no different.

The huge volume of data that can be collected from tyres is beyond most people’s comprehension, especially when most don’t even know they should be checking the tyre inflation pressures on a regular basis.

Early Tyre Pressure Monitoring Systems (TPMS) generate reams of data. The systems used on F1 (Formula 1) cars and MotoGP bikes generate huge volumes, which is used to assist control of the vehicle. An example was relayed to me some years ago by a Moto2 race engineer who mentioned that when slip-streaming a bike (following literally nose to tail), it was observed that the temperature of the front tyre rose by up to five degrees

Celsius. I observe some of the artistic renditions of futuristic trucks and cars where tyres are completely enclosed by bodywork, ostensibly to aid aerodynamics. If the tyres don’t have a stream of cooling air, how do they dissipate the heat that is generated by the hysteresis a tyre experiences during operation? It is evident to me that many fall victim to what I call the Rumsfeld Rule; they don’t know what they don’t know, and worse still, they don’t know that they don’t know.

This could also be called the ‘First Rule of Tyre Technology’, just as I was taught the first law of computing, GIGO. If you have to ask, then you’re already a victim. The vast majority of the population don’t know much about tyres except that when they are flat, it’s a pain.

The fact that they entrust their lives to the humble servant we know as tyres on a daily basis without the basic knowledge is a serious concern to me. In the headlong race into technology, we’ve forgotten to bring the people along with us.

Social media is an example where most, nearly everyone, wants the fruit without having to prepare the soil, then grow the tree until it flowers, then wait for the fruit. ‘I want it now, I want it yesterday and stay tuned because the demands will all change’ (thanks Billy Connolly!) is all too common. The insidious outcome of this media is the ownership of the data, of what you buy, use, view, listen to, eat, where you visit is no longer yours. It is the big corporates that now own your data.

What does this have to do with tyres, I understand you ask. The humble tyre conveys us through our daily travels. It experiences a lot more than we do in that we don’t tread the pavements, or get hot or wet or get bounced over potholes on the road. The array of sensors now being developed for tyres are becoming the control centre of the automotive conveyances, be they fossil-fuelled, EV or HPVs.

What the tyre experiences is transferred into the vehicles control systems, which are then able to direct the motive forces to be applied at the appropriate rate. There is little use in having more brakes than there is traction available; that only results in a brake lock up, which destroys tyres and often results in a loss of control. ABS brakes are a prime defence of tyre lock ups. The tyre can collect the data which can determine your driving style, not only the route you have taken or the load you carry. So the automotive manufacturers will be able to use this data to tailor their solutions to you just as the social media concerns use algorithms to target content to you.

What is not quite as obvious as the data collection aspects is the environmental results of tyre use. Just as there are many unseen outcomes as a result of social media, there are outcomes that are largely unseen involved with tyre manufacture and use.

We go into a tyre shop to purchase tyres; it’s clean and bright or dark and dingy as a traditional tyre outlet or maybe something in-between. This experience tells us zero about how the tyre came into being and how it was landed in the store where you are purchasing it. The deeply technical and diverse agglomerations that are required to produce a tyre range from growing a tree (remember the fruit?) or drilling deep wells for oil, the mining of iron and other minerals to the production of complex chemical compounds used to create the rubbers.

The technology required to produce the single most complex item on today’s automotive machines is largely forgotten when standing in front of a range of tyres on offer. Unfortunately, a purchasing decision may be as basic as ‘what is the cheapest you have’ or preferably ‘what is the safest tyre you have’. As an industry, we’ve forgotten to educate the buying public on why a safe tyre is the item we should be purchasing. The race to the bottom to have low-cost items has yielded more than just cheap prices and substandard products.

Like most industries, there is a legacy of unwanted results; yes, the demise of discussion now we are staying glued to our phones instead of conversing.

Rubber, by its very nature, is a resilient compound that endures the abuse we throw at it when used as a tyre. Think about this for a moment: you purchase a new vehicle fitted with quality tyres, which we all know will be worn out when the tread is down to the tread depth indicators. What happens to the rubber that has worn away? Do you think about it? For those unfamiliar with on road motorsport such as F1 or MotoGP, you may not have heard of the term ‘tyre marbles’. These are chunks of the very sticky soft compound rubbers on tyres that are used for ultimate traction on a road circuit.

The marbles on a road racing circuit are quite obvious and are at the opposite end of the spectrum to the rubber particulates left on our streets and roads as our daily drives pass by. These rubber particulates (P2.5 is the smallest measurable in today’s systems) are particularly insidious as they permeate our environment.

The rubber dust is washed from the pavements when there is rain, dispersed through the drainage systems and then mixed into the outfall, be that a river and then ocean.

Dry dust particulates are dispersed by the winds into the soils. Microplastics ingress is a rising issue. Our technology (as an industry) is found wanting when the environmental aspects of product use is examined. No, I don’t have any answers except to consider magnetic levitation (which is feasible with examples operating) or matter transportation, which is off the planet for me. I raise the topic for consideration within the context of tyre technology. There is an immediate requirement for the recycling of tyres. Such projects, where the carbon black makes up about 40 percent of the recycling project product stream, seem to be an issue but are potentially feasible.

Tyres can be reused by retreading or repurposed in other manners; however, until the general public accept that tyres are more than a grudge purchase, then all the technology is only leading us further into the abyss.

Our industry needs the same energies as are applied to the technology employed to be used in education of our end users so they can grow to appreciate tyres just as we in the industry already do. As fire is a wonderful servant but a bad master, tyres too are wonderful servants but have serious outcomes if we continue to ignore them. Education is required. More technology is not necessarily the best answer.

French tyre major Michelin has introduced its new X Line Grip D range, which is designed to work up to 1 million miles (1.6 million kilometres) with up to four retreads. The company shared its designers' claim that this is a ‘once-in-a-lifetime’ leap in tyre technology for fleets.

In addition to the higher range, the tyres also provide 20 percent more mileage and a 20 percent reduction in rolling resistance compared to the Michelin XDN2 tyre.

Designed to meet both wet and snowy conditions thanks to the chevron tread design, these tyres are said to prove 90 percent better starting traction in snow and over 25 percent better wet starting traction.

Fleets also benefit from using the Michelin X Line Grip D tyre, as it is built on the company’s Duracore casing, featuring Infinicoil and Powercoil technologies. 

Pierluigi Cumo, VP – B2B Marketing, Michelin North America, said, “Michelin is never satisfied with current tyre technology when it comes to constantly improving and innovating our products. That’s why Michelin is so proud to introduce the Michelin X Line Grip D tyre. This tyre has the potential going forward to redefine the drive tyre standard in fleets for years to come. It is not an evolution to existing products, but something entirely different the fleet world has never seen before.”

“Michelin has a proven track record of delivering high-quality, reliable products that exceed performance expectations. This fantastic leap in drive tyre technology bring new levels of performance to the road and new levels of savings to our customers,” he concluded.

The Michelin X Line Grip D tyre is available in sizes 295/75R22.5 and 11R22.5.
