Leave a tyre long enough and it starts to break down, though not where most people look. Everyone checks the sidewall for perishing, because that is where cracks show. The cracking that actually condemns a tyre usually begins at the bottom of the tread grooves, in the rubber between the blocks. Run a fingernail along the base of a groove: if it catches on a row of fine splits, the compound has hardened and lost its flex. Those splits work downwards towards the steel belts, and once water reaches steel, the belt corrodes from within.
None of that shows up in a tread depth reading. The tyre can be legal, quiet and perfectly respectable from a few feet away while the groove bases are crazed. Cars that do short local runs and then sit for a fortnight suffer worst, because it is heat cycling, sunlight and age doing the damage rather than mileage. So it is worth somebody kneeling down and looking properly. Sometimes the verdict is that there are years left in them and the call has cost you nothing.
There is a short list of damage that cannot be repaired at any price, and it is worth knowing it. What we can do is come to the car in Sunbury-on-Thames, confirm which of them you are looking at, and put the right tyre on where it is standing rather than sending you off to find one. We are out on Staines Road West at 2am and in Halliford at 2pm. The Sunbury Cross phone and the Charlton Village phone ring the same fitter, any hour.

The riverside end of the town is full of cars that do two miles a day and then sit for a week, and that pattern ages rubber faster than mileage ever does. Salt through the winter, sun through the summer, and never enough heat in them to matter. If a car lives parked in Lower Sunbury or Halliford and only comes out at weekends, look into the grooves before a long trip, not after one.
A little used car by the river, parked outside most of its life. Plenty of tread, grooves crazed the whole way round, rust showing at the base of one split. Both fronts were changed and the steering settled down in the wet.
A pothole strike leaves a soft raised patch on the sidewall where the cords have parted inside. There is no repair for it and it does not settle down. That one gets changed before the car moves again.
A customer over towards Hampton was convinced a set of tyres was finished. They had surface marks off a hedge and nothing else. We said so, took no money for tyres nobody needed, and checked the spare while we were there.
Fine parallel splits at the base of the groove, running along it rather than across. Early on they look like a texture. Later a fingernail drops into them. Once they are obvious from standing height, that tyre is done.
It can be. A tester fails a tyre where cracking reaches or exposes the cords, and fails obvious bulges and splits outright. Plenty of cracked tyres scrape through a test and are still not something we would happily leave on a car.
No, and it is one of the more common disappointments. A repair relies on the casing being sound. If the rubber around the hole is hard and splitting, the patch is being stuck to something that keeps moving away from it.
You get a straight answer and a price before anything is touched, and if the tyres are fine we will tell you they are fine. We would far rather be called to something that turns out to be nothing than be called too late.
Where age is the problem they are usually the same age, so they tend to go together. Where one has been damaged and its partner is healthy, a single tyre is fine on a front-wheel-drive car provided the pair match for size and pattern.
