Finding a bulge, cut, or crack on your tyre sidewall is alarming — and rightly so. Sidewall damage is one of the most dangerous tyre problems you can encounter. Unlike tread damage, sidewall issues cannot usually be repaired. Here's what you need to know.
The sidewall is the vertical part of the tyre between the tread (the part that contacts the road) and the bead (where the tyre meets the wheel rim). It contains steel or nylon cords that give the tyre its structural strength and absorbs impacts from potholes and kerbs.
In the vast majority of cases: no. Tyre industry standards (British Standard BSAU159) do not permit repairs to tyre sidewalls. The sidewall flexes constantly as the tyre rotates and any repair would be structurally compromised.
A sidewall bulge, cut that exposes cords, or cracking that penetrates the rubber all require immediate tyre replacement.
A tyre with a sidewall bulge should not be driven on at all. The tyre could blow out without warning at any speed. If you notice a sidewall bulge, pull over safely and call for assistance. Do not drive to a garage.
Minor surface scuffing from a kerb is usually cosmetic and does not affect safety — but always have it inspected by a tyre professional to be sure.
Do not continue driving. The tyre could blow out at any moment. Pull over safely, call AK Tyres on 07549 328819, and we'll replace the tyre at your location.
Possibly — some comprehensive policies cover tyre and alloy damage. You can also claim compensation from the local council or Highways England if the pothole was reported and not repaired within a reasonable time.
It depends on depth. If the cut exposes the white or black cords underneath the rubber, the tyre needs replacing immediately. Surface-only cuts should still be inspected by a professional.
Maintain correct tyre pressure (underinflated tyres are far more vulnerable to pothole damage), avoid kerbs, and drive carefully over rough ground. Regularly inspect your tyres for damage.
