The DEKRA test centre hosted another two-day workshop on tyre abrasion last week. The event was part of the ongoing testing of the tyre abrasion methodology adopted by the UNECE Working Party on Noise and Tyres (GRBP).

The event was graced by the presence of representatives from imminent organisations including the European Tyre and Rim Technical Organisation (ETRTO); GRBP; the European Commission's Mobility Unit of the Directorate-General for the Internal Market, Industry, Entrepreneurship and SMEs (DG GROW); the Technical Regulations and Vehicle Approval Office of the French General Directorate for Energy and Climate Change and RDW, the Netherlands Vehicle Authority.

The first day of the workshop saw DEKRA explaining the implementation of the open road tyre abrasion methodology and the ISO 17025 accreditation process, which includes driver training. The participants began by attending the procedures for preparing the vehicle for the test and then measuring the residual tread depth of the tyres personally. The results were different for each of them, though, highlighting the need for specific training even for this basic measurement. The day ended with a briefing on the management and progressive control of the open-road abrasion test and the composition of the convoy.

The second day saw the actual test, where the official convoy of four vehicles was followed by two guest vehicles driven by 2+3 different drivers on a mix of urban-like, regional and highway roads to demonstrate the importance of the driver's ability to maintain the convoy and follow its guidelines. The exercise concluded with a quick review of the speed/time graphs of the convoy and guest vehicles, which demonstrated the possibility of running a convoy test in real traffic and ensuring the same conditions for all cars in the convoy.

The participants learned how the same roads can be used by different customers to test abrasion properties under specific driving conditions. For example, a driver could test high lateral acceleration for sports car manufacturers (80km/h – maximum legal allowed speed) vs. ‘normal’ driving conditions (60km/h) for the R117 abrasion procedure.

Abrasion tests on passenger car tyres (C1) will continue in the following months on tyres of different sizes, models and brands to obtain data for determining abrasion limits for inclusion in the UN Regulation 117 by September 2025. The UNECE tyre abrasion methodology will become the reference methodology of the Euro 7 proposal of the European Union.

The German Rubber Industry Association (wdk) has responded positively to the 'Berlin Declaration’, characterising it as an essential and long-awaited political signal. From the wdk's perspective, the declaration represents a crucial commitment from the ‘Friends of Industry’ to bolster the manufacturing sector, which is fundamental to preserving Germany's industrial core and the multitude of upstream and downstream jobs it sustains. The association's Managing Director, Boris Engelhardt, emphasised that this initiative correctly identifies the urgent need for Europe to recognise and champion industrial value creation.

The wdk finds it particularly significant that the impetus for this declaration originated from a coalition of 17 member states, a fact that underscores a shared political priority independent of the EU Commission's agenda. While the declaration's broad framework allows for various interpretations, the wdk has identified the reduction of bureaucratic burdens as its paramount objective. On this specific point, the association reports being in complete alignment with Federal Minister for Economic Affairs Katherina Reiche. The wdk now asserts that the true measure of the declaration's success will lie in its translation from a political statement into actionable policy, urging the addressed EU institutions to move beyond acknowledgment and proceed with swift and decisive implementation.

Japanese chemicals maker Zeon Corporation raised its full-year operating profit forecast after first-quarter earnings more than doubled, driven by robust demand for battery materials and optical films.

The Tokyo-based company, which produces speciality plastics and synthetic rubbers, posted operating income of 12.1 billion yen ($83.3 million) for the three months to June 30, up 136 percent from the previous quarter and 59 percent higher year-on-year.

Net sales declined 2 percent to 103.1 billion yen from a year earlier, affected by yen appreciation and lower elastomer prices reflecting declining raw material costs. However, sales volumes of optical films and battery materials increased during the period.

The company revised its full-year operating income forecast upwards to 30.5 billion yen from a previous estimate of 28 billion yen. However, this still represents a 9 percent decline from the prior year. Full-year sales are now expected to reach 415 billion yen, up 4 percent.

Zeon maintained its annual dividend forecast at 72 yen per share and said it is proceeding with a share buyback programme of up to 10 million shares or 10 billion yen for the current fiscal year.

The speciality materials business, which includes optical plastics, films and battery materials, generated operating income of 7.4 billion yen in the first quarter, jumping 40 percent year-on-year. Sales in the division fell 3 percent to 29.3 billion yen, partly due to timing differences at overseas affiliates related to the Chinese New Year.

Demand for battery materials remained steady, supported by China’s electric vehicle subsidy policies, whilst shipments to the United States energy storage systems market began during the quarter. The company said European EV sales showed signs of recovery, though inventory adjustments were prolonged.

In optical films, shipments increased due to expanded market share in large-sized televisions, whilst demand remained steady for tablet and smartphone applications.

The elastomer business posted operating income of 4.2 billion yen, up 12 percent from a year earlier, though sales were flat at 58.1 billion yen. The division was affected by weak overseas demand and lower selling prices caused by falling raw material costs.

Zeon also announced plans to sell a portion of its investment securities between August 2025 and March 2026, expecting to book a gain of approximately 10.9 billion yen to improve capital efficiency. The move is expected to reduce its cross-shareholdings ratio to around 11-12 percent of net assets by the end of the fiscal year.

The company said it had completed a reorganisation in June, transferring its chemicals business to the speciality materials division to accelerate decision-making and maximise profitability.

For the second half of the year, Zeon cautioned that optical film shipments are expected to decline due to panel production adjustments and seasonal mobile device demand. However, it described the adjustment as temporary with growth anticipated in fiscal 2026.

Continental is redefining adventure riding for a new generation with the launch of the TKC 80², a complete re-imagining of its legendary TKC 80 tyre. After four decades, this isn't a simple update but a fundamental redesign crafted for today's powerful and heavy adventure motorcycles. It answers a clear call from riders who are increasingly drawn to uncharted paths, yet refuse to sacrifice performance on the journey there. The TKC 80² is engineered to be an uncompromising partner for this dual-purpose lifestyle.

Its performance begins with a cleverly engineered tread. The pattern uses larger, strategically shifted blocks that create more biting edges for superior grip in dirt, sand and gravel. This design also actively resists clogging, ensuring consistent performance where other tyres might pack up with mud. Stability is enhanced through a larger contact area, inspiring confidence whether carving a paved corner or navigating a rocky trail. The logic even extends to direction: the front tread is angled to dig in during braking, while the rear is designed in the opposite way to maximise acceleration traction without excessive digging.

Beneath the tread, a new carcass provides the backbone. It is specifically calibrated for a balanced 50/50 use, offering the robust stability needed for a loaded bike at high speeds or on demanding off-road sections while also improving ride comfort through optimised damping. An advanced rubber compound tackles the classic trade-off, delivering aggressive grip across diverse surfaces while also promising remarkable longevity and wear resistance. This is complemented by RainGrip technology, which instils confidence by maintaining secure handling when the weather turns cold and wet.

Built for epic journeys on every continent and backed by robust puncture protection, the TKC 80² is for those who ride without limits. To fit a broad spectrum of modern travel enduros from brands like BMW, KTM and Ducati, it will be produced in multiple sizes. With its distinct new sidewall icon, the Continental TKC 80² will be available at specialist retailers starting in Spring 2026.

Raphael Michels, Product Manager for Motorcycle Tires at Continental, said, “Our new flexible rubber compound adapts perfectly to the micro-roughness of the asphalt, providing excellent grip. At the same time, we’ve worked intensively to resolve the conflict between on- and off-road performance in the best possible way. The tyre tread combines maximum flexibility for safe wet grip with high block stiffness for stability and mechanical grip.”

Christoph Ettenhuber, Head of Business Field Motorcycle Tires at Continental, said, “With the TKC 80², we’re setting new standards in terms of versatility, robustness and off-road performance. The combination of innovative tread design, new rubber compound and optimised carcass offers adventure riders maximum safety, control and riding pleasure on a wide variety of terrains.”

Bridgestone has confirmed a January 2026 launch for its new premium sports motorcycle tyre, the BATTLAX RACING STREET RS12, in North America. Developed under the concept ‘From Circuit to Street,’ this road-legal tyre is engineered to deliver the highest level of dry grip within the BATTLAX lineup by directly incorporating technologies refined in competitive racing.

The RS12 features a specialised compound derived from race tyre development, which works in concert with a newly designed tread pattern. This pattern’s optimised groove ratio enhances overall tyre rigidity and increases the contact area during cornering for superior grip. A significant innovation for the front tyre is the introduction of the HE-MS BELT structure, a technology previously reserved for top-tier global motorcycle races. This flexible belt system equalises contact pressure to provide a further boost in traction.

By integrating these endurance-racing technologies, the RS12 achieves comprehensive performance improvements on the circuit, with a primary focus on dry conditions. The result is a notable reduction in lap times compared to its predecessor, the RS11. Furthermore, the synergistic combination of its compound, pattern and structure ensures that the high grip level is consistently maintained over multiple laps, resisting performance degradation. This gives riders confidence and a more engaging experience across diverse riding scenarios, from aggressive sport riding on dry pavement to tackling winding roads and dedicated track days.
