Bridgestone Run Flat TiresWith run flat tires, you can punch a hole in your tire and keep on driving, but only for a while. During the next 50 miles, you must stop at a garage or a tire shop to repair or replace your tire.

A run flat tire does pretty much what its name implies. These tires maintain their shape even when damaged. That not only allows you to keep driving, it keeps your damaged tire from popping off its rim. When your tire stays on the rim, the chance of an accident caused by a blowout is greatly reduced.

There are several reasons to choose a run flat tire for your vehicle. Run flat’s

  • keep you from being stranded on the side of the road after a puncture or blowout.
  • help avoid dangerous blowouts.
  • give you more trunk room because there is no need for a spare tire.

How Does a Run Flat Tire Work?

The concept is simple, but the technology is 21st century. Most run flat passenger tires have reinforced sidewalls that are strong enough to hold up your vehicle after a puncture.  Those materials that add the structure and reinforce the sidewalls are the product of modern technology.  These components must be strong enough to support your vehicle without compressed air, but still elastic enough to be part of your tire.

If you have run flats on your vehicle, don’t forget that the point is not to drive forever after a puncture.  The longer you drive on the damaged tire, the more chance you will cause enough additional damage to the tire that it will have to be replaced instead of repaired.

Requirements:

Modern run flat tires don’t need special rims, but they are only functional on cars that are equipped with a working air pressure control system.
