Do you know whether your car is on run-flats? A surprising number of owners do not, and it changes the answer to a puncture completely. A run-flat has a thick reinforced sidewall built to carry the car for a limited distance with no air in it at all, which is genuinely useful on a road where stopping is the dangerous part.
The catch is that the same design makes the tyre very hard to judge afterwards. Running one flat works that reinforcement hard and heats it, and the damage sits inside the wall where no inspection will find it. That is why several makers state plainly that their run-flats are never to be repaired, and why the ones that do allow a repair allow it only where the warning was acted on straight away, the tyre was not driven soft, and the injury sits in the central band of the tread.
So our first question is not where the nail is. It is how far the car went after the light came on, and the honest answer serves you better than the comfortable one.
A puncture found at home on a Sunday used to mean a wasted day and a Monday off. We work seven days and through the night, so the repair happens while the car is still sat where you found it in Hounslow Central. Tight in Lampton, easy in Cranford: neither stops the job. Level in Cranford, sloping in Heston: we set the car straight first.

Run-flats make most sense on roads where the safe thing is to keep moving until somewhere sensible turns up, and there are plenty of those around Hounslow, from the crawl on the High Street to the faster run out past Cranford. What they do not give you is a free journey home. Ring from wherever the warning appeared.
The nail sat centrally and would have been an easy repair on an ordinary tyre. On this one it was a replacement, because the car had covered twenty miles with the warning showing. Nothing looked wrong from the outside, which is the difficulty with these.
A driver in Lampton felt the car go odd, saw the warning and pulled onto the drive within a few hundred metres. The tyre came off, the inner liner was clean, the puncture was dead centre and it was repaired to BS AU 159.
Cars sold on run-flats usually have nothing in the boot at all, so a refusal at the kerb leaves you stranded unless the fitter carries your size. We stock the common run-flat sizes for cars, SUVs and 4x4s for that reason.
Two quick checks. Look in the boot: no spare and no space saver makes run-flats likely. Then look at the sidewall, where the maker prints its own shorthand for the type, and at the handbook, which states it plainly.
Not never, but the bar is higher and it is not ours to lower. Some manufacturers forbid it outright for their own tyres and we follow that. Where a repair is allowed, the casing must still pass the same inside inspection and show no sign of being run soft.
Possibly. It depends on how far, how fast and how much air was left, and none of that can be settled over the phone. What we can do is take the tyre off and look at the liner for the scuffing and discolouration that running flat leaves.
You can, and some owners do, but understand what changes. There is still no spare in the boot, so a puncture becomes a callout rather than an inconvenience. If you go that way, do it in pairs across an axle.
