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.

The Yokohama Rubber Co., Ltd., has launched the ADVAN WINTER V907, a new ultra-high-performance winter tyre, as an afterparts tyre for the Mercedes-AMG E-Class luxury sedan.

The newly developed ADVAN WINTER V907 is designed to provide not only excellent performance on snow but excellent comfort and stability even when driving on dry roads at the high speeds. The tyre features a specially designed tread pattern with V-shaped grooves and 3D sipes as well as a centre rib. These features work in tandem with a special tread compound that combines a cap compound for excellent snow performance and an undertread compound for handling stability on dry roads.

To be sold initially through Mercedes-AMG dealerships in Europe, the new tyre will be available in size 245/45R19 102V for front and size 275/40R19 105V for rear. Both the sizes were jointly developed with Mercedes-AMG and carries the ‘MO1A’ mark on the sides, indicating Mercedes-AMG’s approval. Based on the new afterparts tyre, the company also intends to develop an ADVAN WINTER V907 replacement tyre in a larger variety of sizes. Sales will begin in 2025, mostly in Europe, and will be introduced sequentially at tyre dealers.

BYD has selected Continental’s PremiumContact C tyres as original equipment for its Seal U electric SUV. The electric SUV will come factory-equipped with the premium tyres in size 235/50 R19 99V.

The PremiumContact C tyre provides a pleasant and quiet ride. The rubber compound's unique silica lowers rolling resistance and friction by reducing energy absorption through the tyre while the vehicle is moving. This results in a long tread life and good energy efficiency. Together, a noise-reducing design and noise breakers in the tread pattern greatly reduce the tyre's rolling noise. The PremiumContact C offers a low-impact ride even at high speeds because of its rounded contact patch, which uniformly distributes pressure throughout the tyre.

Continental has been refining tyres for over a decade in an effort to produce ever-lower rolling resistance, minimal rolling noise and high mileage. All of Continental's tyres are able to sustainably lower emissions from combustion cars while still meeting the specifications for electric vehicles. Five most successful EV manufacturers in the Asia-Pacific area use Continental tyres as original equipment, as per the company.

Toyo Tires has introduced the Proxes Sport 2, a high-performance summer tyre designed for sports cars, SUVs and CUVs.

The new tyre features a redesigned profile and advanced tread compounds to enhance performance in wet and dry conditions. Compared to its predecessor, the Proxes Sport 2 offers improved handling, shorter braking distances and a quieter ride.

“The Proxes Sport 2 boasts a 15 percent shorter stopping distance in wet conditions and 10 percent shorter on dry surfaces along with improved handling performance over its predecessor, the Proxes Sport,” said Kevin Arima, senior manager consumer products, Toyo Tire U.S.A. Corp. “These improvements enhance the driver’s experience rain or shine on twisty canyon roads or around town.”
