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.

Portugal’s retreading industry is caught between its established technical capabilities and a market increasingly shaped by low-cost new tyres, regulatory shifts and price-driven purchasing. Associaçao de Recauchutagem de Pneus (ARP) President David Laureano speaks to Tyre Trends about the necessary changes, current state of the industry and how to rebuild confidence and create conditions for investment.

Are policy changes necessary to create a level playing field for retreaders?

I consider policy changes a priority for boosting Portugal’s retreading sector and plan work on four fronts. The first is to review the environmental and economic treatment of retreading so that charges and incentives acknowledge the extension of tyre service life.

The second is to strengthen enforcement of compliance obligations for all operators placing tyres on the market. The third is to introduce criteria regarding lifecycle costs, performance and circularity in public procurement, enabling the participation of technically suitable retreaded solutions.

The last is to facilitate company access to instruments for industrial modernisation, energy efficiency, training and innovation. These measures should be developed in collaboration with public entities and other sector stakeholders. Policy quality improves when those who manufacture, use and manage tyres participate in their formulation.

What are the ARP’s priorities under your leadership?

My priority is to strengthen a unified voice for the sector while respecting the diversity of the companies that comprise it. Building trust among users by demonstrating the quality of domestic retreaders. I want to contribute to an association that stays close to its members and is capable of gathering reliable data, fostering knowledge sharing and presenting well-founded proposals to public authorities.

I also view it as essential to bring the fleet industry, educational institutions and technology partners closer together. We can collaborate on training, research and the dissemination of best practices, thereby strengthening the sector’s collective capacity. The change I would like to see in the market is a more informed purchasing decision, one that recognises tyre performance and the value of extending its service life.

What role can retreading play in reducing raw material consumption and waste?

Retreading preserves a significant portion of the tyre structure by utilising a technically sound casing and enables a new cycle of use. This reduces the need for materials required to manufacture an entirely new structure and postpones the casing’s end-of-life.

Realising this potential requires effective management across the entire value chain including initial selection, maintenance, timely tyre removal and casing inspection. Benefits must be measured rigorously. Savings depend on the tyre type, process and usage conditions; therefore, we must communicate substantiated results rather than applying a single percentage figure to every situation.

What hinders greater acceptance by fleets and consumers?

Doubts regarding quality and safety persist, alongside insufficient information about the industrial process. The perception of poor quality was already among the obstacles identified in the sector characterisation study conducted by Valorpneu in 2019. Trust is built through transparency that requires explaining casing selection, production controls, traceability and the tyre’s suitability for its intended use.

There are specific United Nations regulations for retreading, namely Regulations No. 108 and No. 109. Under these regulations, all operators are required to conduct tests on the tyres they produce, and the tests are identical to those performed on new tyres. The sector also needs to make results more visible through fleet monitoring and comparable usage data.

We cannot focus solely on sales as after-sales service is crucial for building trust and ensuring continuity with the end customer, whether they are transport companies or private individuals.

How can retreading be better integrated into circular economy and sustainability policies?

Retreading should be considered right from the initial tyre selection. This entails prioritising casings designed for extended use, ensuring proper maintenance and establishing systems to evaluate their utilisation. Valorpneu specifically identifies extending service life, the potential for reconstruction and the segregation of tyres with retreading potential as preventive measures.

We would like to see this logic translated into specific objectives and indicators such as how many casings are utilised, how many usage cycles are achieved and how much resources are preserved. These results would help guide incentives and purchasing decisions.

What is the current state of the tyre retreading industry in Portugal?

Portugal possesses a retreading industry with experience, technical expertise and close ties to its customers. Its presence is particularly significant in the heavy-vehicle tyre market. However, it is a sector that needs to strengthen its position.

Commercial pressure challenges companies to demonstrate the product’s value over its lifespan, particularly in a market where the purchase price is a decisive factor. Our ambition is to unite the sector to transform existing industrial capacity into a stronger market presence driven by quality, information and constructive institutional representation.

What is the impact of low-cost imported tyres on retreaders?

Pressure from low-cost tyres is a key concern, one that has also been highlighted in ARP’s public communications. When the decision focuses solely on the initial price, it becomes harder to highlight the value of durability, technical support and the potential to reuse the casing for further service cycles.

Geographic origin alone does not determine a tyre’s quality. We advocate for competition based on verifiable criteria regarding safety, performance, compliance with environmental obligations and lifecycle costs. There is also the issue of continuity as retreading relies on the availability of suitable casings. Therefore, the choice of a new tyre should also take into account its retreadability potential.

Which segments show the highest demand?

Heavy vehicles form the sector’s core base. Road freight transport is therefore a central market, and we see opportunities to strengthen our presence among passenger transport and service fleets, tailored to the specific demands of each operation. There are also specialised applications.

Retreading data for 2024 covers commercial, agricultural, industrial and civil engineering tyres, among other categories. While these figures characterise the activity, they should not be confused with domestic market demand shares. Our goal is to work with each segment to identify where retreading offers a technically sound and economically advantageous solution.

How do regulatory uncertainty and capacity expansion affect investment?

An industrial facility invests with a multi-year horizon. Equipment, training and process improvements require confidence in future operating conditions. When rules or charges change, projects tend to be re-evaluated, complicating investment and expansion decisions.

A concrete example of a shift in the economic landscape is the Ecovalor (environmental fee). In 2025, the Valorpneu schedule indicated a zero Ecovalor for domestically retreaded tyres placed on the market. In 2026, it introduced a specific schedule with a 10 percent bonus, and for the heavy-duty category, the indicated rate is EUR 8.07 per tyre, plus VAT.

We believe that changes of this nature must be accompanied by dialogue with the sector, an assessment of their impact and predictability. Companies need to understand how their environmental contribution will be valued before committing to new investments.

How important is the total cost of ownership regarding demand?

It is fundamental. For a fleet, the purchase price is just one part of the equation. The assessment must include mileage, fuel consumption, maintenance, downtime and casing utilisation. Comparisons must be made under similar conditions regarding load, route, axle position and usage.

Retreading must demonstrate its value in this context through concrete results. I would like to see more long-term relationships between fleets and retreaders with records that allow for tracking cost-per-kilometre and improving decision-making over time. This benefits both parties.

Should retreading be recognised as a strategic industrial and environmental activity?

Yes. That is the vision I want to help affirm. It is an activity that brings together industrial production, technical expertise, transport services and resource preservation. This recognition must be reflected in industrial policies, investment instruments and purchasing decisions.

It must also be accompanied by the sector’s own commitment to quality, innovation and demonstrating its results. ARP aims to contribute to this effort alongside companies, fleets and public entities. We share a common interest in maintaining an industry capable of generating value in Portugal and making better use of the resources on which we all depend.

What is the outlook for the next three to five years?

I see growth potential, but that growth will depend on the conditions we are able to create. Increased fleet focus on operating costs, the need for efficient resource utilisation and industrial modernisation could create opportunities. To capitalise on them, we need suitable casings, customer trust and economic stability.

I would not venture a specific growth rate without a sufficiently solid statistical basis. Ambition must translate into concrete objectives by winning over users, increasing casing utilisation and strengthening corporate competitiveness.
