Run Flat Tyres — Your Essential Guide

Run-flat tyres reinforce the sidewall so a puncture does not immediately collapse the tyre — you can drive limited distance at reduced speed to reach help. They require TPMS and compatible rims.

Types

Self-supporting sidewalls and support ring systems exist; most passenger run-flats are self-supporting.

Pros and cons

Pros: no spare weight, mobility after loss of pressure. Cons: firmer ride, higher price, limited repairability.

Repairs

Many manufacturers restrict repairs after zero-pressure running — follow brand guidance.
