Can you repair or plug a run flat tyre?

Repairing run flat tyres

Most tyre manufacturers and industry guidelines recommend replacing a run flat tyre that has been driven on with low or no pressure instead of repairing it.

Why we do not recommend repairs

• Unseen internal damage - Once a run flat has been driven on while deflated, the reinforced sidewall may have internal damage that is not visible from the outside
• Failure risk - If a run flat is repaired, it could fail at any moment while driving at high speed if the internal parts are damaged
• Warranty - Most tyre manufacturers do not offer warranties on run flat tyres if they have been repaired after flat driving

Very limited exceptions

Some tyre fitters may be willing to repair a run flat tyre if the puncture is minor, located within the middle tread area, and the TPMS indicates the tyre was never driven fully flat. Nevertheless, the general industry recommendation still is to replace the tyre for safety reasons.
