Firestone remains Indycar's tire supplier under Bridgestone and Penske deal

Firestone will continue as the only tire supplier for all IndyCar racing under a long-term extension between Bridgestone America and Penske Entertainment. The length of the deal announced Thursday was not detailed. The agreement will keep Firestone as the only tire supplier for all IndyCar races, the INDY NXT developmental series and the Indianapolis 500. Firestone is wrapping up its 25th straight year as IndyCar’s tire supplier going into Sunday’s season finale at Nashville Superspeedway. Roger Penske said Firestone has been a foundation for racing from the start and this deal continues a relationship setting the standard for success and innovation.
