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.
