Bridgestone Potenza to be OE on Cadillac STS
Bridgestone Potenza RE050A ultra-high performance tires will be original equipment on the 2009 Cadillac STS luxury touring sedan.
The tire will be available in size 255/45R18 99Y for the V6 and V8 models.
Bridgestone Firestone North American Tire LLC (BFNT) supplies two other Cadillac models, the DTS and the Escalade.
The Potenza RE050A sports an asymmetrical tread pattern that "increases surface contact to enhance acceleration and cornering," say BFNT officials.
