Bridgestone unveils sustainable tires for 2025 World Solar Challenge

Tokyo, Japan— Bridgestone Corporation has announced its continued support for the 2025 Bridgestone World Solar Challenge (BWSC), unveiling a new generation of sustainable tires featuring ENLITEN™ technology. These cutting-edge tires mark a milestone in eco-innovation, incorporating over 65% recycled and renewable materials—the highest ratio ever used by the company in motorsports.

The BWSC, set to take place from August 24 to 31, is the world’s premier solar car race, challenging teams to traverse 3,000 kilometers across the Australian outback using only solar energy. Bridgestone, the event’s title sponsor since 2013, will supply these advanced tires to 33 teams from 17 countries.

For the first time, Bridgestone’s ENLITEN tires will include recovered carbon black and steel, sourced through a precise pyrolysis process of end-of-life tires. This breakthrough was achieved in collaboration with ENEOS Corporation and represents a significant step toward a circular economy. The tires are designed to meet the unique demands of solar-powered vehicles, offering low rolling resistance, durability, and lightweight performance.

Bridgestone is also enhancing sustainability across its value chain by reducing tire usage and implementing low-carbon logistics for tire shipments. The company views the BWSC as a “mobile laboratory,” using the extreme conditions of the race to refine its technologies and accelerate innovation for electric vehicles and sustainable mobility.

“With the 2025 BWSC, we’re not just supporting a race—we’re driving the future of mobility,” said a Bridgestone spokesperson. “These tires are a testament to our commitment to sustainability, innovation, and the next generation of engineers.”
