Run flat tires, also known as self-supporting tires, are a type of tire that allows vehicles to continue driving for a limited distance even after a puncture or deflation. This can be a lifesaver in many situations and provide added safety on the road. In this article, we will outline 7 steps to help you identify run flat tires.

1. Check for manufacturer markings: One of the easiest ways to determine whether a tire is a run flat is by looking for specific markings or branding on the sidewall of the tire. Run flat tires usually have “RFT,” “RF” or “ZP” (Zero Pressure) noted on them.

2. Look for a reinforced sidewall: Run flat tires are designed with strong, reinforced sidewalls that allow them to support the weight of your vehicle even when they lose pressure. A thicker and sturdier sidewall can be an indication of a run flat tire.

3. Inspect the bead area: The bead is the inner edge of the tire that sits against your wheel and helps create an airtight seal. On run flat tires, this area may appear more substantial or thicker due to extra materials designed to prevent separation from the wheel during a flat tire situation.

4. Refer to your owner’s manual: Your vehicle’s owner’s manual can be an excellent source of information regarding the type of tires originally installed on your car. If it specifically mentions run flat or self-supporting tires, then your vehicle likely came equipped with them.

5. Check for speed and distance limitations: Run flat tires typically have specific speed and distance restrictions when being driven deflated, which can range from 50-100 miles at speeds up to 50mph (80km/h) before requiring replacement. These details may be printed on the sidewall of the tire.

6. Compare with non-run-flat tires: If you have access to both run flat and conventional tires, you can compare them side by side. Run flat tires will typically be heavier due to the additional materials in their construction.

7. Consult a tire professional: If you’re still unsure whether your tires are run flat or not, consider visiting a tire specialist or automotive service center. These professionals can quickly assess your tires and advise you on the type of tires installed on your vehicle.

In conclusion, by following these 7 steps, you can easily identify whether a tire is a run flat or not. Be sure always to verify the type of tire you have on your vehicle and consult a professional if necessary to ensure safe and confident driving on the road.
