Run-flat tyres are designed to remain driveable after a puncture, allowing you to continue driving at reduced speed for a limited distance without stopping to change a wheel. They are standard equipment on many BMW, MINI, Mercedes and other premium vehicles. Understanding what run-flats can and cannot do helps you make better decisions when the time comes to replace them.
How Run-Flat Tyres Work
Run-flat tyres use a reinforced sidewall that supports the weight of the vehicle even when tyre pressure is lost. This allows continued driving at up to 50mph for typically 50 miles after a puncture — enough in most cases to reach a safe location or tyre fitting service. Because you can continue driving after a puncture without stopping at the roadside, the safety benefit in motorway or rural situations is significant. However, most run-flat tyres cannot be repaired after running flat — a replacement is required.
The Limitations of Run-Flat Tyres
Run-flat tyres are more expensive than conventional equivalents — sometimes significantly so. They also tend to offer a firmer, harsher ride due to the stiffer sidewall construction, though premium brands have narrowed this gap considerably in recent years. Additionally, vehicles fitted with run-flat tyres typically do not carry a spare wheel, so if you switch to conventional tyres you will need to carry a spare or inflation kit. Run-flats also require a tyre pressure monitoring system (TPMS) to work effectively, as you cannot always feel the pressure loss.
Replacing Run-Flat Tyres
We stock run-flat tyres from leading manufacturers and can fit them at your location across Glasgow and Bradford. If your vehicle came with run-flats as standard, replacing like-for-like is usually the safest choice to preserve the vehicle's safety systems and ride characteristics.
