Bridgestone’s DriveGuard™ tires are masterfully engineered to keep you moving after a puncture – even after a complete pressure loss – for up to 50 miles at a maximum speed of 50 mph – so you can get to a safer place. When conventional tires lose air pressure, they go flat. But DriveGuard tires are reinforced with a NanoPro-Tech rubber insert which makes the sidewall capable of supporting the entire weight of the vehicle, even at zero pressure. And Bridgestone’s proprietary “Cooling Fins” create airflow around the tire, reducing heat build-up for added low-pressure mobility. DriveGuard is an all-season tires that delivers the quiet, comfortable ride and long wear life drivers expect from Bridgestone and is backed with a 50 – 60,000 mile treadwear warranty. DriveGuard – continue your journey.
