Every tyre has a side you have never seen. The inner face is where the real evidence lives, and none of it shows while the tyre is on the wheel. Chafe marks in a ring, a bruise where the casing was pinched against the rim edge by a pothole, cords beginning to separate, a grey dust of rubber that has been rubbing against itself. From the outside a tyre like that can look nearly new.
So an honest assessment means breaking the bead and looking. Sometimes what we find is nothing at all, and that is a good result: the kerb scuff was only cosmetic, the tyre goes back on, you have spent very little and you can stop thinking about it. Sometimes the impact that left a small mark outside has broken the casing inside, and then it has to go, because a tyre in that state does not deflate gently. It lets go. We would rather show you the inside of the thing than ask you to take our word for it.
A cut from road debris is the one that catches out careful drivers. Where it is beyond repair, the replacement goes on at the car in Bec Common, balanced, pressures set, old tyre taken away. A 4am Furzedown call and a noon Bec Common call reach the same fitter. Whether it is Amen Corner in rush hour or Mitcham Road at midnight, we answer.

Half of this work is telling people their tyre is fine. That is much easier to do when the car has not been driven anywhere first, and around Tooting Bec and Amen Corner it is usually sitting in the same bay it has occupied all week. Ring while it is parked, we will get the tyre off the rim and look at the side nobody ever sees, and you get a straight answer either way.
Tight bay, alloy scraped, and a genuine worry about what it had done to the rubber. Off the rim, the inner face was clean and unmarked, so the tyre went straight back on. That is a result worth the visit.
A car that barely leaves Furzedown had fine crazing right around both front sidewalls. Low mileage is not kindness to rubber. Sunlight, time and standing in one spot do their own damage, and those tyres were finished.
A faint thumping at low speed with no visible damage anywhere. The inside told the story: a pinch bruise from a pothole, cords broken, the tread starting to lift away quietly. It was days from failing properly.
Because the outside is the half that does not carry the load. Impact damage happens in against the wheel, where the casing gets trapped and crushed for an instant, and the only marks it leaves are in there where you cannot see them.
Not necessarily. A scuffed sidewall with the rubber only rubbed away is usually fine. What condemns it is a cut deep enough to show cords, any swelling, or damage on the inner face where the rim has bitten into the casing.
1.6mm across the central three quarters of the tread, all the way round. Below that the car fails an MOT and is illegal in use. Plenty of tyres are legal on paper and past their useful wet grip well before they get there.
There is no sense in it. We fit tyres every day of the week and the trade runs on people ringing back. If your tyre is sound you get told it is sound, and you have paid for a look rather than for a tyre.
Age matters more than people think on a car doing low miles. Rubber hardens and the sidewalls craze from the outside in, and once that cracking is deep enough to see clearly the casing has lost its flexibility. The date code is moulded on the sidewall.
