What are Run Flat Tyres?
Run-flat tyres are built to handle punctures. If you accidentally drive over a nail or something sharp, run-flat tyres won’t immediately deflate; they’ll get you where you need to go.
How? Well, run-flat tyres have a special design feature: a thickened, reinforced sidewall. This extra rubber provides structure and support when the air pressure drops. So, the tyre won’t collapse; instead, the rigid structure allows you to continue driving for a little longer.
These tyres won’t take you from Exeter to London. You can manage around 50 miles at 50 miles per hour (known as the 50-50 rule). Run-flat tyres should be used with a tyre pressure monitoring system (TPMS) that lets you know if a puncture occurs.

Run Flat Tyres: How Do They Work?
Most tyres rely solely on air pressure. When a puncture occurs, the air pressure hisses out, leaving the tyre useless.
Run-flat tyres also rely on air pressure most of the time. The key difference comes when a puncture occurs. Instead of rapidly deflating, the reinforced sidewalls and additional rubber continue to provide strength and security, guaranteeing you can reach a safe destination.
That being said, there is a downside. Run-flat tyres cannot be repaired. If your tyre suffers a puncture, it’ll need to be replaced as we can’t safely assess the internal structure once driven flat, so replacement is always recommended.

Frequently asked questions.
No. Once punctured, run-flat tyres should be replaced. The internal structure may be compromised, especially after driving on low pressure, which makes safe repairs impossible.
Yes, they usually cost more than standard tyres due to their reinforced design. However, they offer added peace of mind, especially for long-distance or motorway drivers, by allowing you to keep moving after a puncture without an immediate roadside stop.
Technically, yes, but it’s not recommended unless your vehicle has a Tyre Pressure Monitoring System (TPMS). TPMS alerts you to pressure loss, which is crucial with run-flats since you won’t always notice a puncture. TPMS has been mandatory on new UK cars since November 2014.
Yes, run-flat tyres have reinforced sidewalls, which makes them feel firmer on the road. You may notice a stiffer ride, especially over potholes or uneven surfaces.
