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 Alliance for the Future of Tyres (AZuR) has released a revised Green Paper examining tyre circularity across Europe. This document explores the benefits of extending tyre life through retreading, repair and reprofiling, alongside mechanical and chemical recycling. It illustrates how circular economy principles can advance climate goals, preserve resources and strengthen industrial competitiveness.

The paper presents targeted appeals to political leaders, stressing the urgency of adapting legal structures to unlock current potential. It echoes the European Court of Auditors regarding robust recycling markets, which depend on consistent enforcement and dependable funding. Christina Guth, coordinator of the AZuR network, frames the tyre circular economy as a demonstration of sustainable practice, where environmental protection and economic activity reinforce one another.

The paper acknowledges the Clean Industrial Deal as constructive, yet argues circularity must occupy a more central position. Products must be conceived from the beginning with reuse and recycling in mind if materials are to remain in circulation. This gains urgency as the mobility sector expands, bringing increased tyre waste. A functioning circular system for tyres presents an avenue for reconciling ecological pressures with economic development.

The initiative coordinated by AZuR unites more than 80 organisations spanning industry, small business and research. In Germany, over half of the more than half a million tonnes of annual tyre waste is cycled back into use, with collected materials evaluated by certified operators.

Despite existing capabilities, the paper asserts political engagement remains insufficient. It enumerates requests for governing bodies, including support for repair enterprises, binding sustainability benchmarks and inclusion of retreaded options in public procurement. Another element involves cultivating a European market for premium recycled substances.

The paper also advocates for clear regulations regarding novel recycling methods and for recycled content to be granted equivalent status to virgin materials. Such measures are presented as essential for protecting investment in sustainable innovation.

Broader European trends indicate circular systems are increasingly viewed as integral to a resilient industrial approach. Advanced recovery infrastructure aids climate objectives and underpins material security. The European Court of Auditors has called for reinforced policy conditions that enable recycling economies to thrive, highlighting consistent rule application and stable financing for recovered materials.

Hankook Tire, the official tyre supplier to the FIA World Rally Championship (WRC), concluded its participation in the 2026 Safari Rally Kenya, which took place in Naivasha, Kenya, with the event wrapping up on 15 March 2026. The challenging terrain of the Kenyan savanna provided a rigorous test for Hankook’s specialised equipment. Throughout the rally, the company provided its Dynapro R213 tyre, engineered specifically for severe off-road conditions. This extreme all-terrain tyre was available in Hard and Soft compounds and featured a robust casing structure alongside an optimised tread design. These characteristics ensured reliable grip and accurate steering response despite the demands of high-speed rallying.

A key development was the introduction of an upgraded soft gravel tyre at this event. It delivered superior traction on wet and slippery sections while retaining its structural integrity amidst the unpredictable conditions. The rally unfolded across the rugged landscapes of Naivasha and the Great Rift Valley, where competitors faced sharp rocks, deep sand and treacherous fesh-fesh dust. Fluctuating weather further compounded the difficulty, making consistent tyre performance critical for drivers to reach the finish line. Ultimately, Toyota Gazoo Racing's Takamoto Katsuta emerged victorious after four gruelling days, reinforcing the event's reputation as one of the season's most demanding.

Looking ahead, the championship moves to Europe for its fourth round, the WRC Croatia Rally 2026, scheduled from 9 to 12 April 2026 along the Adriatic coast. Returning to the WRC calendar after being part of the European Championship in 2025, the rally has generated significant interest with its redesigned route that navigates both coastal and mountainous terrain. For this event, Hankook will supply its Ventus Z215 and Z210 tyres, high-performance tarmac compounds designed to meet the rigorous demands of the course. These tyres have previously proven their effectiveness in similar environments, such as during the 2025 Rally Islas Canarias, where coastal and mountainous stages demanded exceptional vehicle control and tyre resilience.

Since taking over as the exclusive tyre supplier for all WRC classes in 2025, Hankook has leveraged data from its involvement in over 70 global motorsport championships. The company applies these race-proven insights to advance its ultra-high-performance tyre technology, continually reinforcing its leadership in the field.

Flexsys, a global speciality chemicals and materials technology company, has announced an increase in regional prices for Insoluble Sulphur products with effect from 23 March 2026.

The price increase schedule is as follows:

• Asia: USD 0.60 per kg
• Europe: EUR 0.45 per kg
• North America: USD 0.40 per kg
• Latin America: USD 0.40 per kg

The driving forces behind these significant pricing actions are multifaceted, rooted in substantial disruptions to global supply chains. These disruptions are largely attributed to the ongoing conflict in the Middle East, which has had a cascading effect on logistics. Compounding this issue are the sharply rising costs associated with transportation and essential raw materials.
