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.”

The German Rubber Industry Association (wdk) has issued a statement highlighting the severe threats the ongoing geopolitical crisis involving Iran poses to the nation's rubber value chain. Michael Klein, the association's President, warned in Frankfurt am Main that this new conflict could create existential difficulties for the sector. He reiterated the industry's longstanding appeal to policymakers, stressing that persistently high energy costs have been jeopardising the chemical industry, a fundamental pillar of the German economy, for some time.

The statement points out that the manufacturing sector is already beginning to feel the initial significant repercussions of the military conflict that recently escalated in and around Iran. A primary concern is the disruption to the global gas supply, which risks sustaining long-term damage. Although Germany is not directly impacted by supply cuts from Iran, the conflict has strained global fossil fuel availability to a point where demand cannot be satisfied, inevitably leading to shifts in supply chains and pronounced price increases.

According to Klein, European chemical manufacturers, who are vital suppliers to the German and European rubber industry, are being disproportionately affected by these rising gas prices. He underscored that German companies now face energy costs three times higher than those in United States. The association's president expressed alarm over the closure of significant petrochemical facilities in Germany during 2025, questioning how many more external shocks are necessary for political leaders to counteract the price implications of their own regulations. As an initial and essential step, the wdk is calling for the repeal of the Fuel Emissions Trading Act. At a minimum, they demand its temporary suspension for fuels used to generate industrial process heat, viewing this as just a starting point for much-needed regulatory relief.
