Can a run-flat tyre be repaired?
Run-flats are engineered differently to standard tyres, and that changes the repair-or-replace decision.
Run-flat tyres (marked RFT, ROF, SSR, ZP, EMT or similar depending on the manufacturer) use a reinforced sidewall that can support the vehicle's weight for a limited distance after a total loss of pressure, rather than relying on a separate support ring or sealant.
That reinforced sidewall is exactly what makes the repair question different from a standard tyre. Most tyre manufacturers and UK industry bodies such as TyreSafe advise against repairing a run-flat that has been driven in a deflated or low-pressure state, because the internal structure can suffer damage that isn't visible from the outside.
Repairable vs replacement
The general industry position most manufacturers apply to run-flats.
- Punctured while still at or near normal running pressure
- Not driven any meaningful distance in a deflated state
- Damage is in the central tread area, within standard repair limits
- No visible sidewall distortion or internal structural damage
- Driven any distance with the tyre significantly deflated
- Any sidewall damage or bulging
- The reinforced sidewall shows signs of overheating or separation
- Manufacturer guidance for that specific tyre excludes repair outright
Why the sidewall history matters more than it looks
A standard tyre driven flat for even a short distance is usually visibly ruined. A run-flat is designed to keep supporting the car while looking almost normal from the outside — which means the internal damage from being driven deflated can be invisible without a full internal inspection after the tyre is removed from the wheel.
This is why an honest assessment always starts with a simple question: how far, and at what pressure, was this tyre driven before you noticed the problem? If you're not sure, treat it as driven flat and have it properly inspected rather than assumed repairable.
Frequently asked
Are run-flat tyres more expensive to replace than standard tyres?
Run-flats generally cost more than an equivalent standard tyre because of the reinforced sidewall construction — the exact price depends on the brand, size and specification. Call or WhatsApp your tyre size and vehicle details for a quote.
Can I fit a standard tyre instead of a run-flat as a replacement?
On some vehicles, yes — but many cars fitted with run-flats as standard don't carry a spare wheel and may have a TPMS or suspension calibration set up around run-flat tyre characteristics. Check your vehicle handbook or ask when booking.
How do I know if my tyre is a run-flat?
Look on the sidewall for RFT, ROF, SSR, ZP, EMT or a manufacturer-specific code (BMW uses a star, for example). Our guide on reading a tyre sidewall covers where to look.
