Goodyear Tire & Rubber Company has unveiled a demonstration tyre comprising 90 percent sustainable materials. This demonstration tyre has passed all applicable regulatory testing as well as Goodyear’s internal testing.

Bringing a 90 percent sustainable-material tyre to market will require further collaboration with the company’s supply base to identify the scale necessary for these innovative materials to produce that specific tyre at high volumes.

Goodyear claims that this demonstration tyre also tested to have lower rolling resistance when compared to the reference tyre made with traditional materials. Lower rolling resistance means the demonstration tyre has the potential to offer better fuel savings and carbon footprint reduction.

The tyre company states that the 90 percent sustainable-material demonstration tyre includes 17 featured ingredients across 12 different components, including –

• Carbon black, which is included in tyres for compound reinforcement and to help increase their life, has traditionally been made by burning various types of petroleum products. The demonstration tyre features four different types of carbon black that are produced from methane, carbon dioxide, plant-based oil and end-of-life tyre pyrolysis oil feedstocks. These carbon black technologies target reduced carbon emissions, circularity and the use of bio-based carbons, while still delivering on performance.

• As per Goodyear, the use of soybean oil in this demonstration tyre helps keep the tyre’s rubber compound pliable in changing temperatures. Soybean oil is a bio-based resource that helps reduce Goodyear’s use of petroleum-based products. The tyre manufacturing company claims that while nearly 100 percent of soy protein is used in food/animal feed applications, a significant surplus of oil is left over and available for use in industrial applications.

• Silica is an ingredient often used in tyres to help improve grip and reduce fuel consumption. According to Goodyear, the demonstration tyre includes a high-quality silica produced from rice husk waste residue (RHA silica), a by-product of rice processing that is often discarded and put into landfills.

• Resins are used to help improve and enhance tyre traction performance. In the demonstration tyre, Goodyear states that traditional petroleum-based resins are replaced with bio-renewable pine tree resins.

• Bead wire and steel cords provide reinforcement in the structure of a radial tyre. The tyre manufacturer claims that the demonstration tyre uses bead wire and steel cord from steel with high recycled content, which is produced using the electric arc furnace (EAF) process. The utilisation of the EAF process allows for steel to be produced with reduced energy use and higher recycled content. The EAF process has the potential for lower greenhouse gas emissions in comparison with steel produced using a blast furnace.

• Goodyear claims that ISCC certified mass balance polymers from bio and bio-circular feedstock are also included in this tyre.

In addition, after announcing the capability to demonstrate a 70 percent sustainable-material tyre in January 2022, Goodyear, working with its supply base, plans to sell a tyre with up to 70 percent sustainable-material content in 2023. With the introduction of a tyre with up to 70 percent sustainable-material content, the company claims that it is demonstrating tangible commitment with in-market solutions to building a better future. The tyre manufacturing company states that consumers interested in purchasing this tyre can register for updates at Goodyear.com/SustainableMaterialTire.

“We continue to make progress towards our goal of introducing the first 100 percent sustainable-material tyre in the industry by 2030,” said Chris Helsel, Senior Vice-President, Global Operations and Chief Technology Officer at Goodyear. “The past year was a pivotal one toward achieving this goal. We researched new technologies, identified opportunities for further collaboration and utilised our team’s tenacity to not only demonstrate our capabilities to produce a 90 percent sustainable-material tyre, but to also produce a tyre with up to 70 percent sustainable-material content this year. Our team continues to showcase its innovation and commitment to building a better future.”

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.
