When it comes to tires, understanding their functionality can save you from unexpected surprises. Run-flat tires have been around for a while, but not everyone is familiar with them. In this article, we will discuss how to identify a run-flat tire.

Look for the Label

One of the easiest ways to identify a run-flat tire is to look for the label on the sidewall of the tire. This label typically has the letters “RF” or “RFT” on it, indicating that the tire is a run-flat tire. Additionally, some manufacturers will indicate that their tires are run-flat by labeling them with the word “run-flat” or “SSR” (self-supporting run-flat).

Manufacturer’s Markings and Codes

Here are some manufacturer codes that can be used to identify if you have run-flat tires.

Bridgestone – RFT/ROF/RSC (Run Flat Tires/Run On Flat/Run-Flat System) Component) 

Continental – SSR (Self-Supporting Run Flat) 

Dunlop – DSST (Dunlop Self-Supporting Tire) or DORT (Dunlop Off-Road Tire)

Check your Car’s Manual

Another easy method to identify a run-flat tire is to check your car’s manual. The manual will typically have information about the type of tires your car needs, and if it requires run-flat tires, it will be specified in the manual.
