Run-flat tyres

Keep going after a puncture

Run-flats are reinforced tyres that can run in a deflated condition

If you’re worried about getting a puncture, perhaps because of concerns about your safety, then run-flat tyres are worth considering. 

Run-flat tyres have either a reinforced sidewall or additional internal structure to support the tyre in a deflated condition.

  • Test drive run-flat tyres first as the ride may be firmer
  • Run-flat tyres are more expensive and harder to get repaired

 Run flat tyres

If you do get a puncture in a run-flat tyre you might not notice, particularly on a motorway, because the ride quality will be very similar to normal. This is why run-flat tyres are always fitted together with a tyre pressure monitoring system (TPMS).

Your handbook will tell you about any restrictions on use if you do get a puncture.

  • Expect at least 50 miles range, depending on load, at speeds up to 50 mph.
  • Get the tyre renewed or repaired as soon as possible.
  • If you’re replacing a run-flat tyre, then new one should be the same make.
  • You’ll need to reset the TPMS, once the new tyres fitted, by following the steps in your handbook.

We provide 24/7 roadside assistance.

Repairing run-flats

Inspecting a tyre internally to make sure it’s safe to repair is a basic principle of tyre repair.

  • The repairer will consider the damage and condition of the tyre taking into account the position of the puncture and the extent of any secondary damage – damage that has occurred as a result of running in a deflated condition.
  • If you’ve got run-flat tyres then you’re likely to have driven on the 'flat' tyre at speed for a considerable distance following a puncture.
  • The construction of run-flat tyres can make it difficult to identify any secondary damage.

Even though run-flat tyre repair kits are available to the trade, many repairers may be reluctant or simply refuse to repair a puncture in a run-flat tyre.
