The tyre is an amazing example of something that has served its purpose for more than a century with no drastic functional changes but has yet undergone constant improvement and sometimes fundamental structural changes. Materials have changed from leather to natural rubber, and then to ever-developing compounds of natural and synthetic rubber, as well as chemicals. Structurally, the largest change has been from bias to radial casing construction, and while some tyre products are now largely only radial tyres – passenger car tyres, for example – other vehicle segments still consume a large quantity of bias tyres; in some regions of the world more than others.

While the equipment required to produce bias tyres is fairly simple, and the costs of establishing a production line therefore relatively manageable – roughly speaking it’s a textile production line combined with vulcanizing in simple 2-part moulds – the costs of establishing a radial tyre production line are massive. From rubber calenders to radial steel belt production and angle cutting over bead ring building and green tyre building drums, until finally curing in 8-segment moulds – and many more steps and essential equipment not mentioned in between. Each machine and process is as important as the next, and only the most skilled management of the entyre production flow can ensure that a quality product comes out at the end. So, needless to say, many of the quality improvements of the past decades have come from improving production equipment and knowledge as much as from improving tread designs and rubber compounds.

Chinese factories

Further, as many tyre production equipment manufacturers have expanded to supply all over the world, many production lines have become much more similar to each other as they approach the worldwide optimal standard for balancing production costs and quality. I won’t mention any specific manufacturer names here, but anyone who has visited a tyre factory in China will have had an employee guide proudly point out that they use only the best equipment from manufacturers in the Netherlands, Japan, Germany, and the USA. I’ve always been tempted to ask if the hammer is more important or the person who wields it, but I digress. The fact is that most Chinese factories have also improved drastically in terms of management and comply with IATF 16949 standards to ensure consistently high-quality levels and constantly reduce defects. The main driver and reason for the current standards is the reduction of manual work stations and a large manual labour workforce to largely automatic or at least semi-automatic machinery, reducing the manual labourers to employees simply moving materials or finished products from one place to another. Over time, these will also be made redundant, as machines will also handle this part.

The question remaining is just how factories located in low-wage countries will keep competitive as the necessary equipment costs the same all over the globe, and less hands are needed to operate the massive production lines. When the lines all over the world only need core staff to monitor and make technical adjustments and maintenance work, the difference in the product cost structure can only come from land and building use, logistics and handling costs, as well as water, heating, and electricity fees. Especially the latter, utility fees, probably soon make up the most important factory when it comes to differentiating tyre cost structures across the world.

Global supply

What will this mean for the global tyre supply? Most likely, it will be good news for the environment, as it won’t make as much sense as previously to send products across the globe, because the transportation costs will make the products more expensive than locally produced ones – regardless of production country. Given that all countries play fair, that is, so maybe I should say in a perfect world. There is no doubt that some countries favour their large factories with subsidies or tax rebates more than the developed countries do. But, with the recent massive rise in sea freight charges caused by the pandemic, and amplified by the Ever Given blocking the Suez Canal, the tables could be turned faster than anyone expected. Just until a month ago we all expected the extremely high sea freight levels from Asia to the rest of the world to last just a few months, now the carriers expect that we won’t see normalization – and thereby decreasing rates – again until 2024. As tyre prices from low-cost manufacturing countries have been gradually closing the gap to second tier brands over the past decade (and quality levels have followed suit and in rare cases even surpassed them), they have now very suddenly lost all competitiveness when solely looking at pricing. Surely, it has been the strategy of all these manufacturers for many years to ultimately surpass the competition on quality and performance, but not before surpassing them on price.

So, what will happen now? Nobody knows, but it will be equally interesting and nerve-wracking to follow. For the tyre building machine manufacturers, the dilemma has grown bigger than ever before; should they continue to develop better machines, as they risk killing their clients by doing do? There’s a very narrow path to tread between staying competitive against other machine manufacturers and sustaining the financial health of one’s own clients. (TT)

Goodyear executed its largest-ever endurance operation at the 24 Hours of Le Mans, a feat defined by 188,747 kilometres driven, 377.5 million wheel revolutions, and 44 cars competing across the LMGT3 and LMP2 classes. The Goodyear Racing Eagle tyres delivered relentless performance, supported by over 120 experts and a stock of 8,000 tyres that sustained racing throughout the entire week.

The tyres' exceptional consistency allowed teams to extend stint lengths significantly, saving precious time during pit stops. Most LMGT3 squads completed four stints, or forty laps, before changing rubber, while LMP2 entries routinely managed five. One LMP2 team notably kept a single set for 56 laps, covering 761 kilometres, a distance comparable to travelling from Le Mans to Monaco.

Pace did not diminish despite the high mileage, with the fastest LMGT3 car posting a 100-lap average 1.2 seconds quicker per lap than the previous year, marking the fastest Le Mans of the LMGT3 era. Goodyear’s off-track presence was equally robust, featuring the Goodyear Blimp, a new grandstand, a popular fan activation, a museum collaboration and the introduction of the Goodyear Passerelle.

Ahead of the race, Goodyear reaffirmed its commitment to LMGT3 through a joint announcement with the FIA and ACO, extending its exclusive supply into a fourth season in 2027 with a new tyre composed of 66 percent sustainable materials. The WEC now moves to the 6 Hours of São Paulo on 12 July, though many Le Mans teams will first compete at the European Le Mans Series’ 4 Hours of Imola on 5 July.

Stephen Bickley, Goodyear Endurance Program Manager, said, “When you look at the distances covered without compromising on pace, it underlines the consistency and reliability of our Goodyear Racing Eagle tyres throughout one of the toughest races in the world. It was a special Le Mans for us, felt through our fan activation, partnership renewal and icons old and new at – and above – the circuit.”

The Tire Industry Project (TIP) has initiated a pilot study in collaboration with the Greater Paris Sanitation Authority (SIAAP) and the sustainability consultancy ERM to assess the potential of wastewater treatment plants to remove tyre and road wear particles. The research is being conducted at the Valenton wastewater treatment facility near Paris, which ranks as Europe’s second-largest plant and features advanced treatment technologies representative of modern municipal systems. This investigation is scheduled to continue through 2026.

In numerous urban centres globally, stormwater and road runoff are channelled into wastewater systems prior to being discharged into natural waterways. A clearer understanding of how effectively these treatment processes capture TRWP could guide the broader adoption of optimised wastewater management practices. Currently, systematic data quantifying the removal of these particles within treatment plants remains scarce, and this project aims to generate comprehensive, end-to-end evidence to bridge that knowledge deficit.

The study represents TIP’s first real-world application of a priority mitigation strategy identified in its white paper on addressing tire and road wear particles. Over the coming months, researchers will collect and analyse samples from key stages of the Valenton plant’s treatment cycle using advanced pyrolysis gas chromatography-mass spectrometry. The findings are expected to estimate the total removal efficiency across the entire process and will be submitted to a scientific journal, with publication anticipated in early 2027.

The scientific understanding of TRWP is complicated by a lack of standardised methodologies, the variable nature of the particles and their transformation products, and the diverse environmental pathways they traverse. In response, TIP and its member companies have committed to advancing research on quantification, characterisation, environmental migration and potential impacts while collaborating with value-chain stakeholders to support science-based interventions. A 2024 TIP publication reviewed over 50 mitigation measures and prioritised nine based on upstream and downstream potential, employing a prevention, containment and removal framework.

That review also concluded that no single measure has been proven effective specifically for TRWP and that on-ground validation is essential. Moreover, the paper stressed that no universal solution exists, requiring coordinated, large-scale implementation across multiple actors, including the tyre, road construction and automotive sectors, as well as municipal authorities, academia and other public and private entities. The Valenton pilot thus marks TIP’s inaugural effort to test wastewater management’s real-world efficacy, uniting diverse stakeholders from both the public and private sectors in this critical research.

Larisa Kryachkova, Executive Director, TIP, said, “This pilot is an important step in going beyond understanding the subject in the laboratory to field-based evidence. We expect to identify best practices that can be applied far beyond this project, supporting TIP’s ambition to support science-based mitigation.”

Sabrina Guérin, Head of Innovation Department, SIAAP, said, “As the public authority responsible for wastewater treatment in the Paris region, SIAAP is committed to emerging science that protects waterways. By taking part in this TIP study, we will gain an early, science-based view of TRWP movement in solid waste. The findings can help inform and accompany future treatment planning and readiness for upcoming regulatory requirements.”
