Somebody points at a nail head worn flat and level with the tread and asks how long it has been in there. Weeks, usually. Months sometimes. The head has been ground down by the road into a dull silver disc, and the tyre has not lost a single psi, because the rubber closed around the shank and has gripped it like a cork ever since.
That is genuinely good news. A tyre in that state is very often repairable, because it has never been run soft, the liner inside is clean and the hole is a neat one made by a smooth shank. Pull the nail out yourself and you will hear the air go, and it becomes a job that has to happen now.
Leave it where it is, book a convenient hour, and the same nail comes out with the tyre already off the rim and a plug and patch going in behind it to BS AU 159. What is not optional is doing it at all. A nail sitting quietly today is still working its way in.
DVSA-compliant is not marketing language, it is a description of the method. We do it that way every time, at the car anywhere in TW1, and where the damage falls outside what the standard allows we say so and fit a replacement instead. You watch it happen in Strawberry Hill, or at the kerb in St Margarets. Same tools in Strawberry Hill as in St Margarets, same on every call. TW1 takes in St Margarets and Whitton, and we work the lot.

Half the nails and screws we take out around here were picked up months before anybody noticed them, on a building job off London Road, in a car park near the ground, on a side street in East Twickenham. They travel about for weeks doing nothing at all. Because the car keeps its pressure, there is time to choose an hour that suits you.
A tyre looked at near Twickenham Green had a nail worn so flat it was invisible until a thumb caught the edge of it. No pressure had been lost at any point. It came out with the tyre off the rim and the repair went in the same visit.
Nails do not seal for ever. The shank works loose as the tread wears down around it, and the first sign is a tyre wanting air once a week and then twice. That is the same nail, later, and often still repairable at that stage.
A car in Strawberry Hill had collected two staples in one tread, weeks apart, and neither was leaking. Both sat inside the central band and both were far enough apart to be repaired properly, so the tyre stayed on the car.
Yes, though not this minute. Do not pull it out, and book a fitting at a time that suits you. It is sealed for now and it will not stay sealed, and dealing with it at full pressure is the version that ends in a repair.
Because it moves. Every rotation works the shank a fraction deeper, and every wet day feeds water down the side of it into the steel belt. The seal is rubber gripping a foreign object, not a fix, and it gives up on its own schedule.
You can tell where it sits, which settles most of the question. Central tread is promising, shoulder is not. What cannot be seen from outside is the state of the liner, and that decides the rest.
Not when the repair is done properly. The hole is reamed back to clean rubber, a combined plug and patch is bonded from the inside, and the wheel is rebalanced. Work to that standard lasts the remaining life of the tyre.
