What is Tyre Sidewall Damage?

Kerbs, potholes and underinflation are common causes. Small surface scuffs can be harmless, but cuts to the cords are not. Fine cracks from ageing are also a warning sign. Inspect tyres when washing the car; damage is often easier to spot when clean.

How it works

The sidewall flexes constantly, so damage there can grow and lead to sudden failure.

Why it matters for your car

Have any sidewall cut or bulge inspected and replace the tyre if needed. Avoid scraping kerbs when parking.
