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."

Bridgestone Americas is preparing to introduce three new off-the-road tyres at the upcoming CONEXPO-CONAGG exhibition, showcasing advancements in durability, load capacity and application versatility across its Bridgestone and Firestone brands. The company’s booth will feature these latest innovations – the Bridgestone MasterCore V-Steel M-Traction Deep (VMTD), the Bridgestone V-Steel Rock Deep Ultra (VRDU) and the Firestone Multi Block T – alongside a broader selection of premium intelligent tyres engineered for equipment ranging from cranes and graders to haulers and loaders.

The Bridgestone MasterCore VMTD, a 27.00R49 tyre developed for 100-tonne haul trucks, represents the expansion of the company’s proprietary MasterCore technology into large-scale quarry applications. This new tyre features a traction-oriented tread pattern that delivers a 14 percent increase in tread depth compared to the conventional Bridgestone VMTP tyre, enhancing performance on difficult terrain. Its durable sidewall construction and narrow tread grooves contribute to a 10 percent extension in tyre life, while the MasterCore platform enables a 10 percent increase in load capacity and a two percent improvement in tonne-mile per hour and tonne-kilometre per hour metrics over the previous generation. With this launch, Bridgestone now offers two distinct tread patterns in the 27.00R49 segment, the other being the rock-patterned MasterCore VRDU introduced in mid-2025. The MasterCore VMTD will be available to fleets beginning in June, offered in four compound formulations including standard, cut resistant, ultra-cut resistant and heat-resistant options.

Also debuting at the show is a new three-star VRDU tyre in the 24.00R35 size, engineered with a rock tread pattern specifically for rigid dump trucks operating in quarry environments. This marks the company’s second three-star product in the large tyre segment and extends the hauling benefits of larger VRDU sizes to more compact applications. The tyre incorporates a stronger cord, enhanced casing structure and refined tread design that together yield a 15 percent increase in TMPH and TKPH compared to its predecessor. The new casing construction also provides more than an eight percent gain in load capacity relative to the two-star Bridgestone VRQP tyre. Its tread pattern incorporates slopes and centre grooves that improve wear characteristics while minimising heat generation during operation. This new VRDU size is scheduled for availability in 2027 and will replace the Bridgestone VRQP tyre in the company’s portfolio.

The Firestone brand introduces the Multi Block T radial tyre, designed for articulated dump trucks and wheel loaders, marking a new chapter in the brand’s 125-year legacy of durable products. This model replaces the Versabuilt AP and delivers a 10 percent improvement in cut resistance through strategically placed tie bars, robust steel cord construction and advanced compound formulations. The tyre features a 10 percent deeper tread depth combined with a new block design incorporating biting edges for reliable grip on challenging terrain. Its multi-star rating and non-directional pattern enhance application versatility and simplify tyre management, contributing to reduced operational costs. The Firestone Multi Block T will be available this summer in five sizes including 17.5R25, 20.5R25, 23.5R25, 26.5R25 and 29.5R25.

CONEXPO-CONAGG stands as the largest construction exhibition in United States, taking place from 3 through 7 March at the Las Vegas Convention Center. Bridgestone Americas will be exhibiting at booth 41633 in the West Hall.

Rob Seibert, President – Off the Road, Bridgestone Americas, said, "These three new tyres underscore our relentless focus on delivering premium products that help our customers operate more efficiently. Each tyre is engineered to deliver optimal performance in the most demanding environments, extending tyre life, reducing downtime and lowering total cost of ownership, helping our customers move more with less."
