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.”

New research findings from a doctoral dissertation by Dr.-Ing. Sebastian Bogdahn examine how end-of-life tyres can yield high-quality recovered carbon black (rCB) through pyrolysis while delivering substantial environmental benefits. The work, titled ‘Production and Environmental Assessment of High-Quality Carbonaceous Materials from End-of-Life Tyre Pyrolysis’, was presented in condensed form at an AZuR Chemical Recycling Project Group meeting in Dillingen/Saar on 1 October 2026.

The dissertation tackles how end-of-life tyres can be recovered and recycled to maximise their value. Pyrolysis is identified as a complementary technology that helps close recycling gaps in the circular economy and offers an alternative to fossil-based carbon black, a material that plays a crucial role in determining tyre properties.

In the pyrolysis process, rubber granules from processed tyres undergo thermal decomposition without oxygen, producing three main streams: solid rCB, tyre pyrolysis oil and pyrolysis gas. Previous evaluations of such technologies often separated technical and environmental perspectives, relied on secondary data and lacked standardised methodologies, making findings difficult to compare.

Bogdahn overcomes these limitations by integrating a technology-specific process model with a detailed life cycle assessment model. This combination enables a scientifically robust environmental evaluation of pyrolysis and its secondary raw materials using reliable primary data. A central component is a process model that mathematically describes material conversion by combining reaction kinetics, reactor behaviour and mass and energy balances.

Starting with laboratory-scale experiments, the model was scaled up and validated using a pilot-scale rotary kiln at the Institute of TH Köln. Comprehensive laboratory analyses of feedstocks and products supported development and validation. Optimal conditions for the investigated system were found at 650 degrees Celsius with a residence time of about one hour, achieving complete material conversion and high-quality recovered carbon black. Product distribution was roughly 40 percent rCB, 37 percent TPO and 23 percent pyrolysis gas by weight.

Using validated primary data, Bogdahn conducted a comprehensive environmental assessment and developed a methodological matrix covering relevant standards and guidelines to address inconsistent approaches. In the rotary kiln baseline scenario, one metric tonne of recovered carbon black results in a global warming potential over 100 years of about 918 kilogrammes of carbon dioxide equivalents, compared with the International Carbon Black Association’s global industry average of 3,910 kilogrammes for conventional fossil-based carbon black, a reduction of approximately 77 percent. Even after a quality adjustment for lower carbon content, the reduction remains about 70 percent. The study followed ISO 14067 and underwent independent external critical review under ISO 14071, also covering TPO and sustainable carbon black.

Further improvements remain possible. Emissions mainly stem from electricity consumption and gas combustion, with rCB processing accounting for about 44 percent, pyrolysis gas cleaning and combustion about 36 percent and tyre shredding about 19 percent. Sensitivity analysis confirms that renewable electricity offers substantial additional greenhouse gas reductions, reinforcing that a circular economy achieves genuine sustainability only when powered by renewable energy. Enhancing material quality through demineralisation and activation could enable higher substitution rates for fossil-based carbon black.

A central conclusion extends beyond pyrolysis itself. Raw materials, tyre manufacturing, the use phase and recovery pathways form an interconnected system spanning the entire tyre life cycle, closely linked to the carbon black, chemical, steel and energy sectors. Achieving circularity requires collaboration across systems and industries, along with greater methodological harmonisation and stronger integration of industrial value chains. The AZuR network’s work reflects this need, recognising that extended tyre use, repair, regrooving, retreading, mechanical recycling and appropriate chemical recycling must all function as interconnected elements of the value chain.

Tyres Europe, as part of a coalition of 10 European associations representing consumers and automotive and mobility service providers, has issued a joint press release welcoming the latest CARUSO Connected Vehicle Field Test assessing the EU Data Act’s implementation across 29 major vehicle manufacturer groups. The findings confirm the legislation established important principles for accessing vehicle-generated data and encouraged some manufacturers to engage for the first time. One year on, however, the framework remains insufficient alone to enable a competitive, innovative connected mobility market.

Covering 15 automotive use cases across 28 vehicle manufacturer groups, the study concludes that while data access has improved, conditions for competitive, scalable, multi-brand services are still lacking. Access remains fragmented, inconsistent and often commercially or technically impractical across the car parc. Limited third-party access, differences in data scope, quality and coverage, and restrictive commercial terms continue to undermine the business case for innovative services. Genuine multi-brand development remains unattainable, preventing consumers and businesses from fully benefiting from connected mobility.

For many manufacturers, implementation has become a compliance exercise rather than a genuine effort to enable market access. Independent providers face limited datasets, restrictive terms, manual approvals, manufacturer-specific consent mechanisms and inconsistent technical solutions. Such approaches may satisfy the Data Act’s broadly defined obligations but are incompatible with the real-time, automated access modern digital services require.

Strong enforcement matters. Manufacturers respond faster where national authorities investigate complaints and apply enforcement mechanisms. Without consistent, harmonised, proactive enforcement across the European Union, Data Act rights risk remaining largely theoretical for a significant share of Europe’s vehicle fleet.

The coalition urges European Union institutions and Member States to enforce the Data Act consistently, issue clear guidance on fair, reasonable and cost-based compensation and use forthcoming reviews to reinforce rather than weaken it. Dedicated automotive legislation should establish common access conditions, interoperability requirements, initial technical and data delivery standards and safeguards against discrimination. Effective access must cover vehicle-generated data and the in-vehicle functions and resources needed to develop, scale and deliver digital mobility services, enabling fair competition, growth and investment.

According to the coalition, the Data Act was an important first step, but horizontal legislation alone cannot create a workable multi-brand market. Implementation varies widely: of 28 manufacturers, nine (32 percent) have barely implemented the Act; 18 (64 percent) lack adequate third-party pricing; 18 (64 percent) lack adequate data provision; and 19 (68 percent) lack an adequate API solution. Sixteen manufacturers (57 percent) enable none of the use cases, while only nine support the most feasible ones. Without stronger enforcement and dedicated automotive legislation, Europe will fall short of its innovation, consumer choice and fair competition ambitions.

CEAT reported a 26 percent year-on-year increase in consolidated revenue to INR 47.62 billion in the second quarter of the 2026-27 financial year, while net profit stood at INR 1.12 billion as higher raw material costs continued to weigh on the tyre maker.

The company’s consolidated earnings before interest, tax, depreciation and amortisation (EBITDA) margin was 9.5 percent, according to its unaudited results for the quarter ended 30 September.

Arnab Banerjee, Managing Director and Chief Executive, said revenue growth was supported by premium segments across business units. He added that the conflict in West Asia had kept raw material costs high, prompting the company to tighten cost controls.

CEAT expects to deliver double-digit revenue growth in the second half of the financial year, alongside further price increases, Banerjee said.

On a standalone basis, revenue rose 23 percent year on year to INR 45.48 billion. EBITDA margin was 10.14 percent, while net profit reached INR 1.64 billion.

Kumar Subbiah, Chief Financial Officer, said commodity costs were expected to remain elevated in the third quarter. The company would continue to pursue measured price increases and improve its product mix to manage cost pressures.

Subbiah said debt increased during the quarter, largely because of capital expenditure of close to INR 4.9 billion to expand capacity in areas with high utilisation, as well as dividend payments.

He added that CEAT would maintain financial discipline while investing to meet demand and support profitable growth.
