Firestone’s New Green Race Tires Hit the Track

Firestone Racing is launching a new line of race tires that blend high performance with green technology for the 2026 IndyCar season.

Debut: St. Petersburg Grand Prix
Series Covered: NTT IndyCar Series & INDY NXT developmental series
Production Volume: ~37,000 units
32,000 for the main series
5,000 for junior competition
Size Range: 60 distinct sizes to fit oval tracks, road courses, and street races across all 18 events

Sustainable Core Components

Ingredient	Source	Impact
Soybean‑oil based compounds	Renewable oil	Reduces fossil fuel use
Recycled steel beads	Reclaimed steel	Lowers waste, retains strength
Reclaimed carbon black	Old tires	Cuts environmental footprint
Bio‑derived butadiene & styrene	Palm‑oil residues	Sustainable monomers for rubber
Recycled steel bead wire	Reclaimed steel	Eco‑friendly reinforcement

These materials maintain the rigorous performance standards of open‑wheel racing while cutting dependence on nonrenewable resources.

Firestone’s history of using race testing as a laboratory has led to previous introductions such as:

The 2026 “Firehawk” model continues this tradition with advanced bio‑derived components.

Manufacturing Hub: Bridgestone’s Advanced Tire Production Center, Akron, Ohio
On‑track data continuously refines product design for both Firestone and Bridgestone ranges.
Recycling Commitment: Most IndyCar tires are repurposed into playgrounds, sports surfaces, and other rubber products after their racing life ends.
