The verdict on a puncture is made on the inside of the tyre, not the outside. Once the bead is broken and the casing is open, the inner liner tells you what that tyre has been through since it went soft. A tyre driven while low leaves a signature in there, a dull grey scuffing where the walls have been rubbing against themselves, sometimes with a fine dust that comes off on your glove.
That scuffing ends the conversation. It means the sidewall has been flexing far past what it was built for and the cords inside have been working themselves loose, whether or not anything shows from the outside. A neat nail hole in the middle of the tread is repairable. The same hole in a tyre that has been run flat for a couple of miles is not, because the thing that failed is no longer the hole. So we look for it before agreeing to repair anything at all.
The holiday departure is the one that hurts most, because the whole thing is timed. Ferry, flight, a booked slot at the other end, and a nail found in the tread while the car is being loaded outside the house in Morden town centre. A Ravensbury cul-de-sac or a St Helier main road, tell us which. A tight terrace in St Helier or a narrow bay on Central Road is usually workable.

Traffic in SM4 is slow and constant, which tempts people into creeping toward home on a tyre that is already down. That crawl through the gyratory is what turns a repairable puncture into a new tyre more often than anything else. Stop where you are, even if the spot is awkward, and let the work come to the car instead.
A car came back from Wimbledon on a tyre that had been going down since the morning. The nail was central and looked ideal. The liner was scuffed grey right around the shoulder, so a new tyre went on and the owner saw the inside of the old one before it joined the pile.
A slow leak noticed on a driveway in Lower Morden while the tyre was still holding most of its air. That is the version that gets repaired. Reamer, combined plug and patch bonded to a clean liner, rebalanced, then back on the hub to the right torque figure.
Some cars leave the factory on run-flat tyres with reinforced sidewalls and no spare at all. They will carry you a limited distance after a puncture, but they are usually finished afterwards and most manufacturers say do not repair them. We check what is fitted before promising anything.
Less than most people think, and it depends on load and speed as much as distance. If the steering has gone heavy or the car is pulling to one side, you have already gone too far. Stop and ring.
Because the inside is the evidence. Anything done through the tread from outside is guesswork about a casing nobody has looked at, and guesswork is exactly what we are trying to avoid on the A24.
A repair done to BS AU 159 is permanent, bonded to the liner and sealed through the hole itself. It does not need revisiting and it does not alter the tyre's marked speed rating.
Workplace car parks are among our easiest calls, because the car is standing still all day anyway. Give us the bay and a way in, and it can be finished before you come back out.
Then there is no repair available, from us or from anybody else. The sidewall carries the load and flexes constantly, so nothing bonded into it will stay put. That one is a replacement and we would sooner say so on the phone.
