Run Flat Tyres
Why Use Run-Flat Tyres
When a traditional tyre has a puncture it deflates and you end up with a flat tyre which cannot be used. The advantage of a run flat tyre however, is that after a puncture the tyre will remain stable for a period of time to allow you to get garage - or home to get one of those great mobile tyre fitters to come to you.
How Run-Flat Tyres Work
Run-flat tyres are manufactured with a reinforced side wall. When the tyre is punctured and begins to deflate, the sidewall begins to support the vehicles weight for a short period of time.
How Long Can You Drive On A Punctured Run-Flat Tyre
After a puncture run-flat tyres should only be used for up to another 50 miles and you should travel at no higher than 50mph. However, this is a general recommendation and you should check with the manufacturer as this vary - you should consult their guidance/documentation to find out their suggested speeds and distances following a puncture.
Should You Fit Run-Flat Tyres On Your Next Tyre Change
We only recommend fitting run flats to your vehicle if it was fitted with them at the time of manufacture. Vehicles fitted with run flats require a tyre pressure monitor system (TPMS) to ensure you are aware if the tyre receives a puncture. Without a TPMS run flats can be extremely dangerous and pose a major risk.
From 2014, to comply with new EU rules, all new vehicles must be installed with a TPMS. If this is the case for your vehicle then there should be no issue with changing over to run-flat tyres.
Puncture Repairs on Run-Flat Tyres
Unlike conventional tyres, run flat tyres cannot be repaired once they have a puncture - a new tyre will be required.
