Cadillac run-flat: Bridgestone OE on ATS

The Bridgestone Potenza RE050A RFT (run-flat) from Bridgestone Americas Tire Operations is OE on the 2013 Cadillac ATS, the first-ever Bridgestone run-flat OE fitment on a GM vehicle.

Bridgestone supplies GM with run-flat tires in size 225/40RF18 88W (front) and 255/35RF18 90W (rear) for fitment on the ATS Premium Collection, the highest level package available on the new ATS.

The Potenza RE050A RFT is an ultra-high performance summer tire equipped with race-proven technology that contributes to solid wet and dry traction. Its asymmetrical tread pattern also increases surface contact to enhance acceleration and cornering while at the same time promotes rapid water evacuation and reduction in road noise, says Bridgestone.

Thanks to run-flat technology, the tires are also designed to provide temporary mobility for a distance of up to 50 miles at up to 50 mph after experiencing a total loss of air. This run-flat feature allowed GM to forgo providing a spare tire, wheel and jack or tire inflation kit, thereby also saving weight and trunk space in the ATS design.
