There are 3 main types of run-flat technology – self-supporting, self-sealing, and auxiliary-supported. All new vehicles these days come with TPMS, although some are better than others. They can not be patched like an ordinary tire.Ī tire pressure monitoring system (TPMS) is required for the use of most run-flat tires since it may not be obvious that you have punctured a tire. Once punctured, a run-flat tire should be replaced with a brand new run-flat tire. When punctured, they last 50 miles at a max speed of 50 mph. How Long Do Run-Flat Tires Last? Run-flat tires last just as long as a standard tire under normal use, typically 50,000 to 60,000 miles. This guarantee will let you know how many miles you can expect to get out of your run-flat tires. Run-flat tires usually come with a tire warranty that often includes a tire mileage guarantee. Run-flat tires wear the same as conventional tires and last just as long. Conventional tires last 50,000 to 60,000 miles typically, assuming there isn’t an issue with uneven wear or tire damage.
