Bridgestone today announced that Firestone Racing will usher in the 2026 INDYCAR season with Firehawk race tires that integrate Bridgestone global ENLITEN technology.
While the Firestone brand celebrates 125 years, racing has been instrumental in the development of tires since the early 1900s. Firestone established its winning performance and quickly secured its place in history with Ray Harroun’s victory at the inaugural Indianapolis 500® in 1911.Motorsport remains a vital proving ground for advanced materials and technologies, shaping innovations and tire development that extend far beyond the racetrack.NTT INDYCAR SERIES and INDY NXT by Firestone 2026 SeasonThis season, the Firestone Race Tire Engineering (RTE) team will design, develop, and deliver approximately 37,000 Firestone Firehawk ENLITEN Technology race tires. Of that total, more than 32,000 race tires will be supplied to the NTT INDYCAR SERIES. They span 60 different specifications to meet the diverse demands of oval, road, and street course configurations on the 18-race schedule.The tire allotment also includes 5,000 tires across 18 different specifications, to support the next generation of drivers competing in INDY NXT by Firestone. These tires help provide critical driver development experience over a 17-race schedule and on a competitive platform closely aligned with the NTT INDYCAR SERIES.ENLITEN Technology in INDYCARENLITEN Technology is designed to deliver customized performance while promoting a focus on enhanced sustainability across the Bridgestone and Firestone tire portfolios. This includes consumer products, such as the new Firestone Firehawk Indy 500 V2 ultra-high performance summer tire, as well as commercial and race tires.Firestone Firehawk primary and alternate race tires will incorporate key ENLITEN Technology components1, including:
Renewable soybean oil: Replaces petroleum-based oils traditionally used in tire compounds
Recycled steel: Used for the bead wire that anchors a race tire to a wheel
Recycled carbon black: Reinforcement material recovered from end-of-life tires
Use of these materials helps improve resource efficiency and increased material circularity while meeting the rigorous performance demands of North America’s premier open-wheel racing series.“Firestone Racing serves as a mobile lab to test and prove new technologies under the most extreme conditions,” said Lisa Boggs, Director, Bridgestone Americas Motorsports. “The integration of ENLITEN Technology is the next step in our commitment to no compromises, and sustainably focused technology through the use of cutting-edge materials.”Evolution in Firestone Racing’s Sustainability Efforts For the past three seasons, Firestone successfully proved the use of guayule-derived natural rubber in the sidewalls of alternate race tires on street circuits. Firestone Firehawk Indy 500 race tires also incorporated materials derived from hard-to-recycle plastics (2023) and palm oil waste residue (2024-25). The 2026 Firehawk Indy 500 race tire will once again feature two ISCC PLUS-certified monomers – butadiene and bio-styrene, produced from waste residue of palm oil processing – along with recycled steel bead wire2.Efforts are also ongoing to advance end-of-life recycling initiatives for race tires, moving from energy generation to material circularity. Nearly 100% of the tires used in the NTT INDYCAR SERIES and INDY NXT by Firestone are recycled into new uses beyond the racetrack – including playground and sports surfaces, flooring and other rubber products.Firestone Firehawk race tires are produced at the Bridgestone Advanced Tire Production Center (ATPC) in Akron, Ohio. Opened in 2022, the ATPC marked a new chapter in Firestone’s 125-year history in the community where it was founded. The Firestone RTE team collaborates closely with their colleagues at the nearby Bridgestone Americas Technology Center, where insights gained on track help enhance product development across the Bridgestone and Firestone tire portfolio.About Bridgestone Americas, Inc.: Bridgestone Americas, Inc. is the U.S.-based subsidiary of Bridgestone Corporation, a global leader in tires and rubber, building on its expertise to provide solutions for safe and sustainable mobility.
