A global tyre manufacturer NEXEN TIRE is revolutionising tyre development by integrating advanced technologies such as eXplainable AI (XAI) and 3D printing.

NEXEN TIRE has traditionally followed a multi-step process for tyre development, involving designing structures and patterns, creating molds, manufacturing prototypes, and testing them on vehicles. The company has streamlined this process by incorporating XAI and 3D printing and enhanced product precision.

XAI, an artificial intelligence technology, helps analyse and understand the causes and processes behind machine learning algorithms. NEXEN TIRE uses XAI to analyse various information related to tyre design, such as basic designs, key design variables, performance contributions, and design directions. This maximises design efficiency and helps propose optimal structures and designs that meet tyre developers’ requirements.

NEXEN TIRE leverages XAI-driven designs to create Virtual Tire Models, assessing product performance in virtual environments. This increases accuracy and speed in tyre development. The company’s recent decision to adopt a driving simulator will elevate virtual development further.

Once a model passes the virtual development stage, a physical prototype is produced for final evaluation, which requires mould production. NEXEN TIRE utilises 3D printing technology to make molds, enabling the simultaneous creation of prototypes in various designs and specifications. As these prototypes have already undergone verification in the virtual development process, the chances of final product approval are significantly increased.

Traditionally, mould production alone took two to three months, but with 3D printing, this period can be cut by at least 70%. Additionally, production costs can be reduced by at least 50%, ensuring cost efficiency from the early stages of development.

The 3D printing-based mould manufacturing technology allows for innovative tyre designs that include diverse and complex patterns and sipes. This is crucial for supporting high-performance vehicles and providing consumers with enhanced performance and safety. NEXEN TIRE has applied for an international patent for its 3D printing technology.

By innovating its development process, NEXEN TIRE enhances product competitiveness while reducing time and costs. The company also contributes to sustainable management by reducing waste and costs associated with discarded prototypes.

“The ultimate goal of our technological innovations is to enhance customer satisfaction.” A NEXEN TIRE representative stated, “Transforming the tyre development process not only secures market competitiveness but also contributes to environmental protection during the development process, shaping the future of tyre manufacturing and driving revolutionary change.”

Liberty Tire Recycling has published the industry’s first US company-commissioned lifecycle assessment (LCA) centred on rubber-modified asphalt solutions made from recycled tyres. The study was commissioned by Liberty and carried out by Boundless, applying internationally recognised LCA methodology to evaluate the environmental impacts of the company’s asphalt-related products against conventional alternatives used in asphalt modification.

The company described the assessment as a notable step forward for rubber-modified asphalt. Environmental gains are routinely linked to recycled tyre materials in road building, yet Liberty said this analysis supplies quantified evidence behind such assertions. Greenhouse gas emissions tied to its rubber-modified asphalt solutions were tracked throughout their lifecycle.

Results showed that Liberty's asphalt products carried substantially lower greenhouse gas impacts than conventional SBS polymer modifiers. Recovering and reusing end-of-life tyre materials was also found to deliver environmental benefits exceeding the impacts of processing them. Liberty said the findings give transportation agencies, engineers, contractors and infrastructure stakeholders data-driven insights for choosing materials.

Four products were assessed: crumb rubber and three asphalt additives, namely dry mix rubber additives, a DOT additive and combined micronised rubber powder with the Rheopave additive. Dry mix rubber additives yielded the largest carbon benefit, avoiding up to 0.577 kg CO₂e per pound produced, while the tyre-derived products achieved over 100 percent lower greenhouse gas footprint than traditional SBS modifiers. Each product assessed generated a net environmental benefit, with reductions spanning 0.47 to 0.57 kg of CO₂e per pound.

Liberty said the study helps set a benchmark for measuring and communicating environmental impacts as sustainability gains prominence in infrastructure projects, and that transparent, science-based data will matter increasingly to public agencies and industry leaders weighing performance and environmental goals.

Avon Tyres will make its second consecutive EICMA appearance this year, using the Milan show to unveil a refreshed motorcycle range and a renewed brand identity to a global audience of riders and trade visitors. The company will occupy Hall 9, Booth U65 at Fiera Milano between 3 and 8 November.

The exhibit reflects Avon's ‘made to be different’ philosophy and presents a focused portfolio spanning sport, touring, adventure, cruiser and classic segments. Avon's return also signals progress within Goodyear's motorcycle portfolio, where, since joining the family of brands in 2022, it has paired longstanding heritage with a modern product strategy and upgraded manufacturing.

Four flagship tyres anchor the display: the Spirit ST for sport-touring, the 3D Supersport for hypersport riders, the Roadrider MKII for classics and the Cobra Chrome for cruiser, touring and custom applications, the latter now offered in additional sizes. They are joined by the Trailrider 2, a new adventure-touring tyre launching in January 2027 that carries the ‘made to blaze your own trail’ message, targets an 80:20 road-to-off-road mix and will come in at least 20 sizes for popular adventure bikes.

Together with the existing Trekrider and Streetrunner, the lineup forms Avon's most comprehensive public display of its motorcycle portfolio to date. EICMA, which drew over 600,000 visitors last year including nearly 43,000 trade professionals from 167 countries, gives the brand a truly global stage for engaging riders, dealers and partners. Public-day attendees can also meet stunt rider Rok Bagoros at the stand on Friday 6 November at 11:30.

Roberto Finetti, Marketing Manager Motorcycle Europe, Goodyear, said, “We’re looking forward to speaking with riders and partners at EICMA about our continued growth plans for Avon. EICMA is the world’s largest motorcycle exhibition and provides the ideal place to showcase our refreshed identity and tyre range under the ‘made to be different’ philosophy.”

The all-new Vredestein Quatrac Pro 2 premium ultra-high-performance all-season tyre has had its class-leading capabilities confirmed through independent testing in Spain and Finland. The tyre established new benchmarks for wet braking and recorded the fastest snow handling lap times against four leading all-season rivals.

Testing in Finland at the UTAC winter facility used a sensor-equipped BMW 5 Series to measure speed and lap times, with all tyres subjected to identical procedures. The Quatrac Pro 2 achieved the quickest snow handling lap, showing exceptional grip, balance and controllability, which testers praised for excellent response and stability in all circumstances. Its snow performance is aided by 3D interlocking sipes at the shoulder, whose zig-zagged inner faces in horizontal and vertical planes limit tread block movement.

In Spain, Applus+ IDIADA assessed dry and wet handling and braking on certified asphalt with defined water depth. The tyre outperformed key competitors in wet conditions, delivering a 7 percent wet-braking advantage over one long-established segment rival, and separate testing confirmed an A wet-grip rating across the entire size range, unique in the UHP all-season segment. Four longitudinal grooves in every size, also unique in the category, plus directional lateral grooves, support water evacuation and aquaplaning resistance.

Compared with its predecessor, abrasion resistance has improved by 8 percent to maximise tyre life, while rolling resistance is reduced by 10 percent to boost driving range, underlining suitability for electric vehicles. The Quatrac Pro 2 is available now for wheel diameters from 17 to 24 inches, with section widths up to 355 mm for powerful passenger vehicles.

Daniele Lorenzetti, Chief Technology Officer, Apollo Tyres Ltd, said, “Vredestein has long been recognised for its premium all-season tyres, and these independent tests reinforce that reputation. The Quatrac Pro 2 delivered exceptional grip and traction against other premium competitors while also improving efficiency and longevity compared with its predecessor.”
