The Yokohama Rubber Co., Ltd. has confirmed a continued partnership that will see its US subsidiary, Yokohama Tire Corporation, provide ADVAN racing tyres for three Porsche one-make racing series in 2026. This multi-series agreement includes the Porsche Sprint Challenge North America by Yokohama, the Porsche Sprint Challenge USA West by Yokohama and the Porsche Endurance Challenge North America. All three are sanctioned by the United States Auto Club (USAC) and function as key developmental categories within the Porsche Motorsport Pyramid, featuring race-prepared vehicles such as the 911 GT3 Cup and the 718 Cayman GT4 RS Clubsport.

The upcoming 2026 season represents a significant milestone, marking the sixth consecutive year Yokohama has been the control tyre supplier for the North America and USA West series and the third straight year for the Endurance Challenge. The company will support the competitors with its ADVAN A005 for dry tracks and the ADVAN A006 for wet weather conditions across a combined schedule of numerous events. This ongoing involvement is a strategic initiative designed to bolster the profile and recognition of the ADVAN brand throughout the important North American market.

This commitment to one-make racing extends beyond the Porsche family. Yokohama Rubber is also the official control tyre supplier for the recently launched Mustang Cup, reinforcing its active role and investment in North American motorsport. Through these high-profile partnerships, Yokohama aims to enhance brand power by associating its ADVAN products with some of the most exciting and competitive racing series on the continent.

Hankook Tire, the official tyre supplier to the FIA World Rally Championship (WRC), has confirmed that the 2026 WRC Safari Rally Kenya is scheduled for 12 to 15 March 2026 near Naivasha. This event is recognised as one of the most punishing off-road challenges in the series, set against the backdrop of the demanding African savanna. For this rally, Hankook introduced the new Dynapro R213 soft gravel tyre, featuring an optimised compound for better low-temperature flexibility and superior grip on wet surfaces, while its adaptable structure ensures consistent durability under severe conditions.

Departing from its customary Nairobi start, this year’s competition will concentrate entirely on the harsh gravel terrain surrounding Lake Naivasha in the Great Rift Valley. Drivers will need to quickly adjust to newly designed, high-intensity stages and refine their race tactics from the very beginning. Spanning four days, the rally consists of 20 Special Stages covering roughly 350.52 kilometres. Competitors will encounter a treacherous mix of deep sand, sharp rocks, expansive savanna sections and the infamous fine ‘fesh-fesh’ dust, all compounded by swiftly shifting weather. In this unpredictable environment, tyre resilience, grip and handling stability are paramount to performance.

The Safari Rally consistently draws significant global motorsport attention. Since its return to the WRC calendar in 2021, the Toyota GAZOO Racing World Rally Team has achieved five consecutive victories at this event. Nevertheless, strong challenges are anticipated from both the Hyundai Shell Mobis World Rally Team and the M-Sport Ford World Rally Team, promising a fierce contest for the win.

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.

The Board of Scandinavian Enviro Systems AB (Enviro) has resolved to file for bankruptcy for its fully owned subsidiary, Tyre Recycling in Sweden AB. A formal petition has been submitted to the District Court of Gothenburg to initiate the process. This action forms part of the broader company reorganisation currently underway for the parent company and is specifically intended to improve Enviro’s liquidity and support its long-term profitability.

The subsidiary in question operated a recycling facility in Åsensbruk, which was instrumental in validating both the company’s technological processes and the products derived from them. Having successfully fulfilled this developmental role, the facility’s ongoing operations are no longer strategically essential. Given that the site has not been financially viable, the Board determined that filing for bankruptcy for the subsidiary was the necessary course of action.

This decision is projected to negatively impact Enviro’s financial results through an impairment charge of approximately SEK 84 million (approximately USD 9.14 million). Despite this measure, Enviro’s core operations in Gothenburg will continue without disruption, running in parallel with other initiatives being implemented under the reorganisation framework. It is important to note that the company reorganisation applies exclusively to the parent company, Scandinavian Enviro Systems AB, and not to its subsidiaries.

The Yokohama Rubber Company has confirmed a renewed partnership with KONDO RACING for the 2026 motorsport season, marked by a shared pursuit of victory in the highly competitive SP9 class at the Nürburgring 24-Hour Race. The team will campaign a Ferrari 296 GT3 EVO, equipped with Yokohama’s ADVAN racing tyres, across both the Nürburgring 24-Hour Race (ADAC RAVENOL 24h Nürburgring) and the Nürburgring Langstrecken-Serie (NLS).

This collaboration brings together a proven combination. KONDO RACING, under the leadership of Masahiko Kondo, has consistently demonstrated its capability on the global stage, competing in elite series such as SUPER GT and SUPER FORMULA in Japan, as well as enduring the rigors of Le Mans. Their history with Yokohama at the Nürburgring includes a notable ninth-place overall finish in 2019. More recently, the team showed formidable pace in 2025, securing second place in the qualifying race and remaining a contender among the frontrunners throughout the final event. This performance provides a strong foundation for their 2026 campaign, where the objective is a class victory.

KONDO RACING Director Masahiko Kondo

Yokohama Rubber’s commitment to the Nürburgring extends beyond its partnership with KONDO RACING. The company will continue to provide its high-performance tyre technology to multiple leading teams competing in the NLS and the 24-hour race. The overarching goal is to secure another overall championship, leveraging the reliability and handling precision of its tyres to conquer one of the world’s most demanding circuits. This renewed agreement reinforces a longstanding relationship built on shared success in both domestic Japanese competitions and gruelling international endurance events.

A new study from the California Office of Environmental Health Hazard Assessment (OEHHA) has concluded that crumb rubber infill made from recycled tyres and used in synthetic turf fields poses no significant health risk to those who use or observe them. The comprehensive evaluation found no evidence linking these fields to cancer or other health issues for athletes, officials, coaches or spectators, including young children.

These engineered fields, designed to replicate natural grass, are popular due to their low maintenance, water efficiency and durable, consistent surface. Their widespread adoption in California includes over 900 installations. The infill itself consists of small granules from recycled waste tyres, which help keep the artificial blades upright and provide cushioning and traction.

OEHHA conducted the study to support California's sustainability efforts, specifically its Waste Tire Program, which seeks safe and beneficial uses for recycled materials that would otherwise go to landfills. To ensure a thorough assessment, researchers tested 35 different fields, varying in age and location to represent all of California's climate zones. Multiple samples were taken from each field to account for material differences, and air quality was monitored both during active play and at rest.

The study’s scope was unprecedented, analysing over 100 chemicals of potential concern, far more than previous investigations. In collaboration with Lawrence Berkeley National Lab, researchers simulated human sweat and digestion to identify all chemicals to which a person might be exposed. To understand exposure pathways, OEHHA partnered with UC Berkeley and the University of Arizona. They surveyed over a thousand soccer players, ranging in age from 7 to 71, about their playing habits and observed games to document contact with the turf. The analysis used data from goalies, who have the most frequent contact, to estimate the maximum risk for all players, also considering the potential exposure for a crawling toddler. The final analysis indicated that risks related to cancer, reproductive harm or sensory irritation were negligible.

Kris Thayer, Director, OEHHA, said, "This study should ease concerns about the safety of crumb rubber use in synthetic turf fields. Athletes of all ages can use these fields without parents worrying about this commonly used material."

Zoe Heller, Director, CalRecycle, said, "Protecting public health is our top priority, and California is committed to making sure waste tyres are managed safely so they don’t litter communities or pose risks to residents. CalRecycle appreciates the work of OEHHA and its partners to advance our understanding in support of a cleaner, healthier circular economy."
