Bridgestone DriveGuard is the next generation of run-flat tyre technology, available from May 2014.
The innovations introduced by the Japanese tyre manufacturer move from the new rubber compound to the heat dissipation system and to the reinforced sidewalls (capable of supporting vehicle weight).
DriveGuard is an all-season tyre, suitable for both winter-cold and hot temperatures and weather conditions, and designed to provide the same safe driving and comfort as “conventional” tyres. DriveGuard tyres have different specific designs for sport cars, sedans, and vans equipped with Tyre Pressure Monitoring System (TPMS). These tyres give drivers the capability to continue driving up to 50 miles (80 kilometers) if a puncture occurs (when a DriveGuard tyre experiences air loss, the TPMS icon lights up and the driver knows how long to still drive the vehicle, after the puncture). Patented heat dissipation system has been specially designed to improve the heat transfer generating when a tyre is punctured, as the air loss increases the contact surface between the tyre and the road.
Reinforced sidewalls are able to support the weight of the vehicle, even when the tyre loses all its air pressure.
