Bridgestone Americas completes one year of using Firestone Firehawk race tyres with sidewalls made from natural rubber sourced from the guayule desert shrub, grown in the American desert southwest. 

Over the past year, these guayule-derived tyres have demonstrated outstanding performance on street course races, meeting the same rigorous specifications as traditional hevea rubber tyres, said the company. This success showcases guayule as a viable and sustainable alternative to conventional rubber sources, making strides in domestic sourcing and enhancing sustainability in motorsports.

The guayule-derived tyres made their competition debut at the 2022 Big Machine Music City Grand Prix in Nashville and are set to compete again as the alternate tyre during the upcoming race weekend in Nashville between 4 and 6 August. 

Key Achievements in 2023:

For the 2023 INDYCAR season, alternate tyres using guayule-derived natural rubber has been featured in all five street course races.

Bridgestone utilized more than an acre of guayule to develop the 1,863 guayule-derived alternate tyres for the 2023 INDYCAR season.

The top speed recorded on guayule-derived tyres is 190 mph, matching speeds with non-guayule alternate tyres.

Benefits of guayule include:

The heat tolerant, woody shrub thrives in America’s desert southwest.

Guayule can be farmed with existing row-crop equipment, making it a competitive crop and cutting costs for farmers.

As a domestic source of natural rubber, guayule can have a positive economic effect while aiding in reducing the energy and other environmental impacts associated with the transportation of rubber from overseas.

Dunlop (company name: Sumitomo Rubber Industries, Ltd.) has commenced supply of its Dunlop SP SPORT MAXX 060 and e. SPORT MAXX tyres as original equipment for Toyota Motor Corporation’s new C-HR+, an all-electric vehicle launched in Europe in December 2025. This BEV model combines a stylish design with an expansive cabin and achieves a greater driving range than previous versions through enhancements including modified battery cells.

The supplied tyres contribute directly to this improved range by utilising a new tread rubber compound that lowers rolling resistance. They also provide a quieter ride, a benefit of their optimised tread pattern design. In addition to delivering strong steering stability and wet grip performance, the tyres feature the proprietary Nano Black technology. This technique produces a deeper, richer black on the sidewalls, enhancing the visibility of the Dunlop branding and lending a more premium aesthetic to the vehicle.

The Yokohama Rubber Co., Ltd. has expanded its established partnership with Mitsubishi Motors Corporation through the selection of its GEOLANDAR SUV tyre as original equipment for the newly launched 2026 Delica D:5 minivan. This latest generation of the vehicle, which debuted in Japan in January, features the tyre in size 255/55R18 98H.

For this new application, Yokohama engineers focused on refining the tyre’s performance, achieving enhancements in fuel economy and a reduction in external noise compared to the already well-regarded predecessor.

The GEOLANDAR SUV line is engineered primarily for modern minivans and on-road-focused SUVs, balancing the demand for everyday comfort and safety with versatile utility across diverse surfaces. Yokohama’s relationship with Mitsubishi extends beyond this single model, with the GEOLANDAR brand appearing on several vehicles in the automaker’s portfolio. Notably, the GEOLANDAR G94 model has been supplied in recent years for the Triton and Pajero Sport, underscoring a continued mutual confidence between the two companies.

This tyre supply agreement aligns with the comprehensive updates characterising the new Delica D:5. Mitsubishi has introduced refreshed exterior and interior styling while incorporating sophisticated all-wheel control technology and advanced driver-assistance systems. These improvements collectively elevate the distinctive dynamic character and driving capabilities for which the model is known, with Yokohama’s tyres contributing directly to its on-road performance and efficiency.
