Clunks, Drifts and Odd Tyre Wear: Catching Pothole Damage Before It Costs You
Britain's roads have never been shy about reminding drivers they exist. As winter 2026 settles in, the freeze-thaw cycle, standing water and grit are doing their usual number on the surface. Potholes that were a nuisance in autumn become edge-of-the-road craters by January. And your car takes the hit quietly — until a clunk, a vibration or a tyre bulge turns into a bill.
Why pothole damage is sneaky
A pothole doesn't have to be huge to cause trouble. A square-edged hole at 30mph can pinch a tyre sidewall, buckle a wheel rim, knock the tracking out or shorten the life of a suspension bush. You might drive away thinking you've got away with it. Weeks later, the tyre is worn on one edge, the steering wheel sits slightly off-centre and there's a knock over speed bumps. By then, the damage has had time to spread.
Warning signs worth taking seriously
Tyre trouble
Look for bulges in the sidewall, cuts, tears or a wheel rim that's been dented. A bulge means the internal structure is damaged — that tyre is not safe, no matter how much tread is left. Uneven wear across the tread or on one edge can point to alignment or suspension trouble. If a tyre starts losing pressure after a pothole hit, get it checked before your next motorway trip.
Noises over bumps
A new clunk, knock or rattle over speed bumps or rough tarmac is a classic sign that something in the suspension or steering has been shaken loose or worn. It might be a drop link, a bush, a top mount or a ball joint. None of them get better with age.
Steering that feels off
If the steering wheel is no longer straight when you're driving in a straight line, or the car pulls to one side, the alignment may have been knocked out. Vibration through the wheel at speed can also point to a damaged wheel or tyre.
A harsher ride
If the car bottoms out more easily, feels crashy over small bumps or seems to bounce after a dip, a shock absorber or spring may have taken a hit. A broken spring is an MOT failure and a safety risk.
A five-minute check you can do yourself
Park on level ground with the engine off and the handbrake on. Walk around the car and look at each tyre: sidewalls, tread, valves and rims. Check for bulges, cuts, screws and dents. Look at the gap between the tyre and the wheel arch — if one corner sits lower, a spring may be broken. Press down firmly on each corner and let go; if the car keeps bouncing, the shocks are suspect, though this isn't a definitive test. Check tyre pressures when cold and note any that have dropped. Finally, sit in the driver's seat, turn the wheel gently and listen for clicks or creaks.
When to book a proper inspection
Book a garage inspection if you've hit a pothole hard enough to make you wince, if any warning sign appears, or if your MOT is due soon. An inspection is usually cheap — often free with a service or MOT, or £20–£40 on its own — and it can catch a worn ball joint or a bent wheel before it ruins a tyre. If a tyre has a sidewall bulge or cut, don't wait: replace it or get it checked immediately. Driving on a damaged tyre is a false economy with a nasty worst-case scenario.
What a garage should check
A proper pothole check looks at tyres and wheels, suspension springs and shocks, top mounts, wishbones, bushes, ball joints, drop links, track rod ends and wheel bearings. They should also check alignment if there's uneven wear or the steering is off. The MOT test covers tyres and suspension condition, so pothole damage can turn into a failure if it's left. Alignment itself isn't part of the MOT, but the tyre wear it causes can be.
The £500 question
The source of that scary figure is simple: one pothole can damage a tyre (£60–£150), knock out alignment (£40–£70), and leave you needing a suspension arm or wheel repair (£150–£300+). Add a hire car or lost time and £500 disappears quickly. Catching it early might mean a £40 alignment check instead of a new tyre and a suspension rebuild.
Report it, too
If you hit a pothole that's clearly dangerous, report it to your local council. Take photos, note the location and the date. Compensation isn't guaranteed, but reporting helps get the road fixed and gives you a record if you decide to claim.
The takeaway
Pothole damage rarely announces itself with a bang. It shows up as a clunk, a drift, a bulge or a tyre that's worn on one edge. Give your car a quick look this week, especially if you've been thumping over broken tarmac. If something feels different, get it checked. A cheap inspection now is a lot easier to swallow than a tyre blowout or a suspension bill later.
