Bridgestone Offers a Smooth Ride Even with a Flat

I’ve been lucky enough to have never had a flat tire on a roadway. I’ve found my tire flat in my driveway, having run over a nail the day before which produced a slow leak. I came close to a flat while driving only once and that was scary enough. My tire had a small football-shaped bubble on the side which made a funny noise. This caused me to stop to investigate and replace it with my spare. On the way home from my destination the tire exploded in the back of my car. There was no damage but it sounded like a gunshot inside the car, producing some extraordinary emotional discomfort.

There have been tires that continue to operate even after having gone flat for quite some time. The major drawback to these is that they produce a rather uncomfortable driving experience whether they are inflated or not, due to the extremely stiff sidewalls necessary for them to do their job. This has been the trade-off for the security of knowing you don’t have to change your tire on the side of a busy road.

Bridgestone believes they have the answer for bridging comfort and security in their new DriveGuard tires. This is the first aftermarket run-flat tire designed for use on vehicles that were originally equipped with standard factory tires. They claim to have been able to manipulate the rubber compound at the molecular level (read “magic”) to give the tire the ability to ride as smoothly as a normal tire and shed its own heat through the use of patented cooling fins on the sidewalls. It is capable of running 50 miles at 50mph while flat.

They are so sure of themselves that they are offering a 30-day trial on the tires which go on sale next month. If the tire has to perform its run flat feat during the first year or 12,000 miles Bridgestone will replace it if it can’t be repaired. The final price has not been set but it’s likely they will run $400-$800 a set, which is comparable to a set of premium standard tires.
