Traditionally, run-flat tires have been used mainly for limited vehicle types as specified by certain manufacturers for Original Equipment use. Prime examples of this is are BMW 3 Series vehicles since the mid-2000s, the new MINI Cooper and all fifth-generation and newer Chevrolet Corvettes. These vehicles once represented a small portion of the market that relied on the use of run-flat tires to keep the vehicle mobile due to the lack of a spare tire and jack kit. The expectation of a run-flat tire is that it can support the weight of the vehicle without air pressure and provide extended mobility to get you to your destination without being stuck on the side of the road.
With the introduction of the DriveGuard, Bridgestone looks to not only capture market share on this segment, but also introduce run-flat technology to markets who would have otherwise never considered it. While the DriveGuard may not ride quite as softly as a traditional tire, it has made huge advances from earlier generation run-flats in terms of its ride comfort and longevity. Given the tire's competitive price-point, attractive mileage warranty and capable all-season ability, it may be something for you to consider if you have any fear of being stranded or do not have a spare tire and wheel assembly.
The only requirement for using a run-flat is that your vehicle must be equipped with tire pressure monitor sensors. This represents most vehicles produced in the last decade and all vehicles manufactured from 2008 and onward.
To date, the Bridgestone DriveGuard has been released in 32 sizes allowing for broad market coverage in wheel diameters from 15"-19".
