Run-flat tyres promise to get you home after a puncture — but they cost more and ride stiffer. Are they right for your car?
Run-flat tyres are increasingly fitted as standard on new cars — particularly BMW, Mini and some Mercedes models. They allow you to continue driving after a complete loss of tyre pressure for up to 50 miles at a maximum speed of 50mph. But should you replace them with run-flats, or switch to conventional tyres?
How Run-Flat Tyres Work
Run-flat tyres have reinforced sidewalls — typically made of stiff rubber reinforced with heat-resistant inserts — that support the vehicle's weight even when the tyre is completely deflated. Unlike a conventional tyre, a deflated run-flat maintains its shape well enough to drive on.
The Pros of Run-Flat Tyres
- No need to change a tyre at the roadside
- Better safety if a blowout occurs at speed
- Frees up boot space — no spare tyre needed
- Reduced risk of aquaplaning after puncture
- Peace of mind for motorway driving
The Cons of Run-Flat Tyres
- Significantly more expensive than conventional tyres
- Firmer, less comfortable ride quality
- Cannot always be repaired after puncture — must be replaced
- Only available in certain sizes
- Require TPMS to know tyre is flat
Can You Replace Run-Flats with Normal Tyres?
Yes — if your car was originally fitted with run-flats but has a spare tyre provision (or you're happy to carry a puncture repair kit), you can switch to conventional tyres. Many drivers find the improved ride quality and lower cost worthwhile. We can advise on the best option for your specific vehicle.
