What is a run-flat tire?
A run-flat tire is a tire that can run without air pressure while allowing the driver to keep driving. They have a stiffer sidewall that allows it to sustain the weight of the vehicle even without air. To use run-flat tires, a vehicle needs to be equipped with a TPMS (Tire Pressure Monitoring System) to ensure the driver is aware air loss has occurred. Some vehicles come equipped with Run-flat tires from the factory. These vehicles are generally not equipped with a spare tire as a replacement in the case of a puncture or sudden air loss. If your vehicle is so equipped, your new tires should be Run-flat as well. Run-flat tires are indicated on the sidewall differently with all tire manufacturers. Here are a few: SSR, EMT, ZP, DSST, EMT RFT, SSRF, TRF, ZPS.
