Tyres are one of those things that tend to get checked only when something has already gone wrong. A slow puncture, a failed MOT, a warning from a garage during a service, that’s usually when most people find out their tyres were overdue attention. The problem is that worn car tyres don’t always make themselves obvious, and the difference between a tyre that’s fine and one that’s genuinely past it isn’t always easy to spot without knowing what to look for.
Getting ahead of it makes life considerably easier. These seven signs are worth checking regularly, especially before longer journeys or heading into the colder months.
The tread depth is getting low
The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre, but most tyre specialists recommend considering a replacement well before that point, around 3mm is a more practical threshold, particularly in wet conditions where tread depth has a direct effect on braking distances.
The 20p test is a quick and easy way to check at home. Place a 20p coin into the main tread grooves, if the outer band of the coin is visible, the tread is likely getting close to the legal limit and worth having assessed properly. Doing this on all four tyres every few weeks takes very little time, and if the results aren’t reassuring, it’s worth acting on sooner rather than later.

The sidewalls look cracked or damaged
Sidewall condition is easy to overlook because most people focus on the tread when checking tyres. But the sidewall takes its own share of wear; UV exposure, temperature changes, and age, all cause the rubber to dry out and crack over time, even on tyres that haven’t covered many miles.
Fine surface cracking isn’t always an immediate cause for concern, but deeper cracks or any visible bulging is a different matter. A bulge in the sidewall indicates internal damage to the tyre structure and means the tyre should be replaced without delay, it’s not something that improves or stabilises on its own.
The car is taking longer to stop
This one is harder to notice gradually, which is what makes it worth being aware of. As tread wears down, the tyre’s ability to channel water away from the contact patch reduces and stopping distances increase, particularly on wet roads. If the car feels like it’s taking more road to come to a stop than it used to, or if braking feels less responsive in damp conditions, tyre condition is one of the first things to check alongside the brakes themselves.
There’s vibration through the steering wheel
Some steering vibration can come from wheel balance or alignment issues, but it can also point to uneven tyre wear or internal tyre damage. If the vibration is new, has been getting progressively worse, or appears at certain speeds, it’s worth having both the tyres and the wheel balance checked at the same time to identify the cause.
Car tyres ageing even without obvious wear
Mileage isn’t the only factor in tyre condition, age matters too. Most manufacturers recommend replacing tyres after around five to six years regardless of how they look, and certainly by ten years. The rubber compounds degrade over time even on low-mileage cars, and an older tyre can look perfectly serviceable on the surface while no longer performing as it should in an emergency situation.
The manufacture date is marked on the tyre sidewall as a four-digit code, the first two digits are the week, the last two are the year. It takes seconds to check and is particularly worth knowing for a second car that doesn’t cover many miles throughout the year.
Tread wear is uneven across the tyre
If one part of the tyre is wearing faster than another, heavier on the inner or outer edge, for example, it usually points to an alignment or suspension issue rather than the tyre itself. Running on an unevenly worn car tyres reduces grip and handling predictability, and replacing the tyre without addressing the underlying cause will simply repeat the same wear pattern on the new one.
The tyre keeps losing pressure
The tyre that needs topping up regularly isn’t just inconvenient, it’s a sign something isn’t right. It could be a slow puncture, a damaged valve, or a problem with the wheel rim seal. Running consistently underinflated affects handling, increases fuel consumption, and accelerates tyre wear, so a tyre that won’t hold its pressure properly is worth investigating rather than just repeatedly inflating.
Most of these signs are straightforward to check at home on a regular basis, and catching any of them early tends to mean a more straightforward and less costly outcome. For a car that covers school runs, commutes, and family trips throughout the year, keeping on top of tyre condition is one of the more practical things to stay ahead of.
