Pothole Damage — What It Does to Your Tyres and What to Do

The UK's roads are plagued by potholes, and every year they cause thousands of tyre failures, damaged wheels and even suspension damage. A single deep pothole can wreck a tyre in a fraction of a second — and the damage is not always obvious straight away.

This guide explains the types of pothole tyre damage, what to check after hitting a pothole, and what to do if you find damage. If you have hit a pothole and want a professional inspection, our mobile puncture repair team can come to you — call 01279 881234.

Why Potholes Are So Damaging

A pothole is a sharp-edged hole in the road surface. When a tyre drops into one, the impact compresses the sidewall suddenly and violently. The force is concentrated on a small area of rubber and can damage the tyre in several ways at once — sometimes without any visible mark on the outside.

The harder and faster the impact, the more likely damage becomes. Low-profile tyres on large alloy wheels are particularly vulnerable because there is less sidewall to absorb the blow.

Types of Pothole Tyre Damage

Sidewall Bulge or Bubble

A bulge on the sidewall indicates that the internal cords and belts have been broken. The tyre must be replaced immediately — a bulge can fail without warning at speed, causing a blowout. A bulged tyre is not repairable.

Puncture

Sharp pothole edges can cut the tread or sidewall, causing an immediate puncture or a slow leak. Tread-area punctures may be repairable if they are small and within the repairable zone; sidewall cuts are not.

Sidewall Cracking

A hard impact can crack the sidewall rubber, weakening the tyre's structure. Cracks may appear immediately or develop over the following days as the damaged rubber flexes.

Pinch Cut (Impact Break)

When a tyre is pinched between the pothole edge and the wheel rim, the inner sidewall can be cut or the internal belts broken. This often shows as a small vertical slit on the inner sidewall — hard to see without removing the wheel.

Rim Damage

Potholes can also crack, bend or gouge alloy wheels. A bent rim causes a persistent slow leak as the tyre bead no longer seals perfectly, and a cracked rim may not hold air at all. See our alloy wheel care guide.

What to Do After Hitting a Pothole

1. Pull over safely as soon as you can and inspect the affected wheel visually
2. Check for obvious damage — bulges, cuts, deflation, or a cracked rim
3. Check the pressure — a small drop indicates a slow leak; check again after 24 hours
4. Listen and feel while driving — vibration, pulling or a new noise all point to damage
5. Have it inspected professionally if in any doubt — internal damage is not visible from outside

Can a Pothole Puncture Be Repaired?

A repair is only safe if the damage is in the central tread area, small (typically under 6mm), and the tyre's internal structure is intact. Sidewall damage, shoulder damage, bulges and impact breaks cannot be repaired — the tyre must be replaced. All our repairs follow the British Standard BS AU 159.

If a repair is not possible, our mobile tyre fitting service carries a wide range of sizes on the van so we can replace the tyre on the spot.

Pothole Compensation

If a pothole causes tyre or vehicle damage, you may be able to claim compensation from the relevant highway authority (the council or National Highways for motorways and A-roads). You usually need to report the pothole, provide evidence (photos, location, date) and show that the authority failed to maintain the road. We can provide an invoice and a written condition report to support your claim.

Don't Ignore a Pothole Impact

Even if the tyre looks fine, internal damage can develop into a dangerous failure weeks later. If you have hit a pothole hard, have the tyre checked. Call us on 01279 881234 — we come to you across Essex, Hertfordshire and Cambridgeshire and can inspect, repair or replace the tyre the same day.
