How to Determine If Your Tires are Run-Flats

Friday, May 3, 2013 by Colin .

Run-flat tires have become standard equipment on many vehicles. Some cars of the same general model will have certain versions that come with run-flats while others do not. It can certainly get confusing for people who aren't familiar with different vehicle and tire models. 

All run-flat tires have a designation on the sidewall that indicates they are not standard tires. For example, the Bridgestone Potenza RE960AS Pole Position has a run-flat and non-run-flat model in certain sizes. The run-flat model has the letters "RFT" following the name. You can see this by clicking on the Bridgestone Potenza RE960AS Pole Position RFT photo below.

Different tire companies use different designations for run-flat tires. Continental uses "SSR", Goodyear uses "RunOnFlat" or "EMT", while Michelin designates their run-flat tires with "ZP."

Many customers are convinced they have run-flat tires because their vehicle didn't come with a spare. This isn't always the case, so be sure to check your tires' sidewall to confirm. Now that you've determined if you have run-flat tires or not, you can determine which option you would prefer. To help you make a decision, read "Deciding Between Run-Flat and Non-Run-Flat Tires."

Are my Michelin Latitude Alpin Radial X 235x55x18 run-flat tires?

Hello
We don't list that tire model in your size. Do the tires have ZP on the sidewall after the name? If not, they aren't runflat
