Bridgestone Americas has announced a significant evolution for the 2026 INDYCAR season, as Firestone Racing will equip the series with Firehawk race tyres featuring the company's global ENLITEN Technology. This integration of sustainability-focused innovations begins immediately with this weekend’s Firestone Grand Prix of St. Petersburg, impacting both the NTT INDYCAR SERIES and the INDY NXT by Firestone support series.
This development arrives as the Firestone brand marks its 125th anniversary, a legacy deeply intertwined with motorsport. Firestone’s competitive pedigree was established in the early 1900s and solidified when Ray Harroun secured victory at the inaugural Indianapolis 500 in 1911 using Firestone tyres. Racing continues to serve as a critical proving ground, driving advancements in materials and technology that ultimately benefit tyre development for everyday consumers.
For the 2026 season, the Firestone Race Tire Engineering (RTE) team will produce approximately 37,000 Firehawk ENLITEN race tyres. Over 32,000 of these are destined for the NTT INDYCAR SERIES, requiring 60 distinct specifications to handle the unique challenges of ovals, road courses and temporary street circuits across an 18-race calendar. An additional 5,000 tyres, spanning 18 specifications, will support the INDY NXT by Firestone series, providing a developmental platform for rising drivers on a 17-race schedule that closely mirrors the premier series.
The ENLITEN Technology integrated into these race tyres represents a commitment to enhanced sustainability without compromising performance. The Firestone Firehawk primary and alternate compounds now incorporate key components such as renewable soybean oil, which replaces traditional petroleum-based oils. They also utilise recycled steel for the bead wire and recycled carbon black derived from end-of-life tyres, improving resource efficiency and material circularity while meeting the extreme demands of open-wheel racing.
This move builds on several years of sustainability initiatives by Firestone Racing. Previous efforts have included the successful use of guayule-derived natural rubber in sidewalls on street circuits, as well as incorporating materials from hard-to-recycle plastics and palm oil waste residue. The 2026 Firehawk tyres also continue the use of ISCC PLUS-certified monomers from palm oil processing waste. Concurrently, Firestone is advancing end-of-life recycling, with nearly all race tyres from the series being repurposed into products like playground surfaces and flooring.
All Firestone Firehawk race tyres are produced at the Bridgestone Advanced Tyre Production Center in Akron, Ohio, a facility opened in 2022 that represents a new chapter in the brand’s history. The engineering team works in close collaboration with the nearby Bridgestone Americas Technology Center, ensuring that insights gained from the racetrack directly inform and enhance the development of tyres across the company’s entire portfolio.
Lisa Boggs, Director, Bridgestone Americas Motorsports, said, "Firestone Racing serves as a mobile lab to test and prove new technologies under the most extreme conditions. 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."
