Firestone will remain the sole tire supplier for IndyCar through the 2018 season.
Bridgestone Americas Tire Operations LLC and IndyCar announced the decision Friday. Former series CEO Randy Bernard had discussions with Continental Tire about signing on as a series title sponsor and tire supplier, but drivers were unanimously opposed to a move away from Firestone.
Firestone has supplied tires to IndyCar since the series began in 1996. Firestone is expected to increase its investments in the series, though details were not disclosed.
The expanded agreement begins in 2014 and includes tires and technical support, investments in advertising, promotions, race title sponsorships and other programs. Title sponsorship and tire status for the Indy Lights series will run through 2013.
