Recognise sidewall damage, document the problem safely and know what to tell a tyre fitter.
A new lump on a tyre sidewall after a pothole impact should not be treated as a cosmetic mark. The outside may show only a small change, but the important question is whether the tyre's structure has been damaged.
What does a bulge mean?
Michelin explains that a sidewall bulge can indicate damage to the cords inside a tyre. Its guidance is to replace a tyre with this damage. Sidewall punctures and cuts are also outside the normal repairable tread area. Do not try to flatten, patch or ignore a bulge.
Stop and arrange an assessment
Park in a safe location and avoid continuing a journey on a suspect tyre. If the vehicle is beside moving traffic, keep yourself safe before looking at the wheel. A photograph is helpful only when you can take it without stepping into danger.
Record the affected corner, when the impact happened and whether the tyre lost pressure. Mention any new vibration or change in steering to the person assessing the vehicle. Ask whether the wheel and related components also need inspection; a tyre photograph cannot establish their condition.
Information for the replacement enquiry
Have the registration, tyre size and location ready. If the lettering is hard to read, send a clear sidewall photograph from a safe position. Tell the provider about parking restrictions or difficult access before agreeing a visit.
Reporting the road defect
Bolton Council has a highway reporting form. Use the official route to identify the location and describe the defect. Keep your notes and photographs separate from the booking request so both are easy to find. Reporting a pothole does not establish that a compensation claim will succeed.
Can I wait until my next service?
A visible bulge needs prompt action, not a future-service reminder. Explain what you can see when contacting a tyre professional and agree a safe plan for the vehicle.
Common questions about sidewall damage
Is a photograph enough to confirm the damage?
A photograph can help a fitter understand your enquiry, but it does not replace inspecting the tyre and checking whether the wheel also needs attention.
Can a tyre bulge be patched?
Michelin advises replacement for a tyre with a sidewall bulge. Do not book a normal tread puncture repair as a solution for this type of damage.
Should I drive to get the tyre inspected?
Avoid continuing on a suspect tyre. Discuss a safe plan with a professional and use emergency assistance where the location creates immediate danger.
