Why do tyres wear unevenly?

Last updated 6 June 2026

Key takeaways

Uneven tyre wear points to a specific cause: worn shoulders mean under-inflation or alignment, a worn centre means over-inflation, one-sided wear means alignment, and patchy or feathered wear points to balancing or suspension issues. Read the pattern, fix the cause.

Uneven tyre wear is a diagnosis, the pattern tells you what's wrong. Fixing the underlying cause protects your new tyres; ignoring it just wears the next set out the same way. Run your hand and eye over each tyre and you can often spot the problem before a fitter even looks. Here's how to read the main patterns.

Both edges (shoulders) worn

Worn outer edges with a healthier centre usually means under-inflation. A soft tyre flexes too much, so the shoulders take the load while the centre lifts away from the road. Check your pressures first, as this is the most common and most fixable pattern, and the cheapest to prevent.

Centre worn, edges fine

A worn centre strip with healthy edges points to over-inflation. Too much pressure bulges the tyre in the middle so only the centre touches down and wears. Set the correct pressure from your door placard and the wear evens out going forward.

One edge only

Wear on a single inner or outer edge is the classic sign of misalignment, specifically camber or toe being out. It often appears after a pothole or kerb strike knocks the angles out, and it can ruin a tyre quickly if left, sometimes in just a few thousand miles.

Patchy or cupped wear

Scalloped, patchy wear usually means a balancing problem or worn suspension components such as shock absorbers. The wheel is effectively bouncing as it rolls, taking rubber off in uneven scoops. If new balancing doesn't fix it, the suspension is the next thing to check.

Feathered tread

Tread blocks worn sharp on one side, which you can feel by running a hand across the tyre, points to toe misalignment. It's a subtle one to see but easy to feel, and it's another reason to have alignment checked rather than just replacing the tyre.

How to read your own tyres

You don't need any tools to do a quick wear check. Look across the full width of each tyre, comparing the two shoulders and the centre, and run your palm gently across the tread in both directions to feel for feathering or cupping. Do it on all four, because the front and rear often wear differently, and the pattern on one corner can reveal a fault you'd otherwise miss. Combine it with the 20p test and you'll spot most problems early, while they're still cheap to fix. TyreSafe lists uneven wear as a key thing to check on every tyre.

Fix the cause, then the tyres

Replacing a tyre without fixing the cause just wastes money, because the new one wears the same way. We'll inspect the wear, advise on the likely cause, and replace tyres at your location across the UK, telling you what to get checked. Book an inspection.

Frequently asked questions

What does wear on both tyre edges mean?
Usually under-inflation. A soft tyre flexes so the shoulders carry too much load while the centre lifts away. Check and correct your pressures, then monitor whether the wear evens out.
What causes one-sided tyre wear?
Wheel misalignment, specifically camber or toe being out, often after hitting a pothole or kerb. Get the alignment checked, because the wear will keep eating one edge until it's corrected.
What does cupped or patchy tyre wear mean?
It usually points to a wheel balancing problem or worn suspension parts like shock absorbers, which let the wheel bounce as it rolls and scoop rubber off in uneven patches.
What does a worn centre strip on a tyre mean?
Over-inflation. Too much pressure bulges the tyre's centre so only the middle contacts the road and wears, while the edges stay healthy. Set the correct pressure to fix it.
Can I tell what's wrong just by looking at tyre wear?
Often, yes. Shoulder wear suggests under-inflation, centre wear over-inflation, one-edge wear misalignment, and patchy wear a balancing or suspension issue. A fitter can confirm and pinpoint the cause.
