Quick Answer

The primary advantage of Bridgestone's DriveGuard line of run-flat tires is their ability to withstand being driven on safely for up to 50 miles at speeds up to 50 mph after sustaining a puncture.

Bridgestone DriveGuard run-flat tires are all-season tires intended for use on sedans, coupes and wagons but are not available for larger SUVs and pickup trucks. The run-flat technology of DriveGuard tires improves safety and convenience by allowing drivers to drive vehicles with punctured tires to a safe place or a service center to change tires rather than having to change tires in unsafe areas or in inclement weather conditions. In addition to the run-flat features of these tires, DriveGuard tires feature a 60,000-mile limited warranty for tread wear and a comfortable and quiet ride.

Though run-flat tires such as the Bridgestone DriveGuard have potential safety advantages, many consumers report being unhappy with run-flat tires in general. Run-flat tires do not generally handle as well as conventional tires, according to a J.D. Powers customer satisfaction survey. In addition, consumers often replace run-flat tires rather than repairing them in the case of a puncture, so they can be more expensive than regular tires over a long period.
