Bridgestone has introduced a new addition to its Potenza ultra-high-performance line: the RE-71RZ extreme summer tyre. Designed specifically for grassroots racing, this tyre succeeds the acclaimed RE-71RS model. It aims to deliver quicker lap times and sharp, responsive handling, empowering drivers to maximise their performance on the circuit. A cornerstone of its design is the incorporation of ENLITEN technology, Bridgestone's next-generation platform focused on enhancing durability and advancing sustainable product design.

The tyre's development directly targets key performance metrics. On-track testing at Japan's Tsukuba Circuit demonstrated significant improvements, with the RE-71RZ achieving lap times approximately three-quarters of a second faster than its predecessor in both dry and wet conditions. This gain is attributed to several advanced engineering features. A new high-grip rubber compound, developed using insights from motorsports and proprietary NanoPro-Tech, enhances traction at a molecular level. The tread pattern has been redesigned with a stiffer construction and a larger outside shoulder to improve grip and stability, while a strategically placed main groove on the inside edge helps suppress uneven wear for longer track life. Furthermore, Bridgestone utilised its unique ULTIMAT EYE digital modelling tool to optimise the tyre's structure, creating a more uniform contact area for superior cornering grip.

Professional drivers Masahiro Sasaki and Yuji Tachikawa provided critical feedback during development, their expertise helping to refine the tyre's track-focused characteristics. The Potenza RE-71RZ builds upon a legacy that began in 1979, crafted for enthusiasts who demand competition-ready performance that transitions from daily driving to weekend motorsports. It has been approved for competition use by the Sports Car Club of America (SCCA) and will be eligible for Solo and Time Trials events starting in 2026. The tyre will be offered in 45 sizes and is scheduled to launch in the North American market on 31 December 2025.

Sasaki said, “As its strong point, the Potenza RE-71RZ achieves a high level of performance in both grip and controllability. It delivers improved dry and wet performance for street use while also achieving faster lap times and better wear resistance on the track. This tyre delivers high performance in various situations, making it enjoyable and easy to handle for both everyday driving and track use.”

Tachikawa said, “This tyre is designed for easy handling, allowing anyone to experience precise control along with excellent grip. The tyre is focused on quick warm-up for immediate, high-grip performance as well as reliable wet grip, resulting in a well-balanced tyre suitable for various driving conditions.”

Kuraray America, Inc. marked National STEM Day on 8 November by spotlighting a community educational event that brought together 15 of its volunteers and students from the Houston Japanese Supplementary School at San Jacinto College for a day of hands-on exploration and discovery.

Participants engaged in activities illustrating how science, technology, engineering and mathematics (STEM) converge in chemical manufacturing. Experiments with superabsorbent polymer beads explored chemistry and material properties, while a tour of the college’s facilities introduced industrial equipment. Students also learned about water filtration and distillation processes and how mathematical concepts underpin scientific and engineering applications.

One student showed particular interest in the distillation tower, linking the experience to the Kuraray Group’s contributions to everyday life and its mission of achieving for people and the planet what no one else can. The event also benefited KAI volunteers, who shared technical knowledge, exchanged perspectives and learned alongside potential future scientists and engineers.

Kuraray America thanked Reiko Fuwa and Tomohiro Tani for coordinating the visit, Hans Vandommele for sharing his expertise and all 15 KAI volunteers. The company also expressed appreciation to San Jacinto College for facility access and to the Houston Japanese Supplementary School students for their curiosity, enthusiasm and thoughtful questions.

Liberty Tire Recycling attended the 2026 SEMA Show in Las Vegas, held from 3–6 November at the Las Vegas Convention Center. The automotive aftermarket event, one of the industry's largest, drew over 160,000 attendees from the automotive, tyre and transportation sectors to review new products, technologies and business opportunities.

The Lakin Tire brand, a consistent SEMA exhibitor, once again used the show to reinforce industry relationships and present Liberty's tyre collection, recycling and sustainable resource management capabilities. Personnel from Grade/Used Tires, Commercial Truck Tires, Metals, Recycling and Collection, together with corporate and regional leadership, met customers, suppliers and industry professionals from around the world.

The booth received existing and prospective customers from numerous tyre and automotive segments during the week. Costco Wholesale Corporate Office, United Tires and UTU Wholesale were among the organisations that stopped by to examine Liberty Tire's products, services and nationwide reach. The company viewed the event as an effective forum for monitoring emerging market trends and demonstrating its position in recycling and sustainability, alongside its focus on innovation, workforce development and circular economy principles.

A memorable moment came when a high school shop teacher and students, attending through a special educator programme, toured the booth to learn about tyre recycling and industry operations. Liberty team members provided industry insights, outlined career pathways and acknowledged educators' contribution to developing future skilled trades professionals, supplying tyre inflation gauges for classroom use.

Laufenn, Hankook's associate brand, earned a ‘Good’ ratingwith an overall score of 2.2 for its G Fit 4S in the Auto Bild Allrad all-season SUV tyre test published on 8 October 2026 (issue 41). The tyre competed credibly against 11 rivals from established premium marques, finishing competitively in a 12-strong field.

Wet handling proved a particular strength, with the G Fit 4S collecting the second-highest rating shared with other models. Aquaplaning resistance also impressed, as the tyre held its line until stability began to fade at roughly 100 kmph (62 mph). In snow, it recorded the third-shortest braking distance, matching two other contenders.

Testing spanned snow, wet and dry disciplines, each weighted equally in the final ranking, with a third-generation MINI Countryman serving as the test vehicle. Snow assessments were carried out in New Zealand, while European venues hosted the wet and dry evaluations. The jury's conclusion underscored Laufenn's value-focused positioning, finding the G Fit 4S a solid option for cost-conscious buyers.

Tyres Europe has underscored that tyres qualify as fully recyclable under ISO 22628:2002 and UN Regulation No. 133, describing the established methodology as a robust foundation for assessing tyre recyclability. The organisation recently set out its position on the matter.

The distinction between recyclability and actual recycling rates is central to the group's argument. Recyclability refers to the technical potential of a product and its materials to be recycled, while the real rate hinges on treatment capacity and demand for secondary raw materials. Regulatory frameworks should therefore separate the two concepts clearly and align with an internationally recognised standard.

Tyres consist of rubber compounds, chemical additives and reinforcing textile and steel cords, and at end of life they are separated into rubber, textile and steel fractions, all of which existing mechanical or chemical routes can recycle. Mechanical processing yields rubber granules and powders usable as secondary raw materials across many applications, recovered textiles can be further processed and valorised, and cleaned recovered steel can re-enter metal recycling and steelmaking.

Tyres Europe pledged continued cooperation with policymakers and value-chain partners to strengthen circularity and maximise recovery of valuable tyre materials in Europe, with the full paper available on its website.
