It helps to know which of the two situations you are in, because they call for slightly different things. A tyre that went down in seconds, with a bang or a hiss you could hear, has usually had something substantial go through it, and the car will have gone heavy in the steering almost immediately. In that case stopping quickly was right and there is nothing else to be gained. A tyre that has been quietly losing air for days, the sort that is low every Monday morning and fine again after a top up, is a different animal. There is no drama and no urgency, but there is a decision, and the decision is to stop feeding it and have it looked at while it is still worth mending.
Either way the car stays where it is. Around here that is usually settled for you anyway, since an estate bay in Stockwell Park is not something you give up lightly and the Clapham Road offers nowhere to stop at all. Ring, say whether it went down fast or slowly, and that alone tells the fitter a good deal about what to expect. The tyre is broken off the wheel at the bay, the inside of the casing is inspected properly, and you are told plainly which of the two it turned out to be. Cars, SUVs and 4x4s, round the clock, all year.
The compressor kit in the boot buys you time and nothing else. It will get a soft tyre back up to pressure for a short trip, and it will do exactly nothing about the screw that let it down, or about the casing damage if the tyre has already been run flat. Sealant is worse: it hides the damage and often kills the pressure sensor. A fitter coming to the car is the version that ends the problem: wheel off on Brixton Road, a proper look at the real damage, a repair to standard if it qualifies, a replacement from the van if it does not. We cover SW9 round the clock for it.

Stockwell gives a car two ways to lose its air: something picked up on the Clapham Road where the traffic never lets up, or a slow weep that only shows itself in a parking bay on a cold morning. The fast one you have already responded to correctly by stopping. The slow one is the one people put off, and it is the one that quietly costs them the tyre. Either way the work happens where the car already stands.
A driver heard it go and had the car stopped within a few car lengths. The object had gone straight through the tread and out again, and because nothing had been driven on it the casing was still sound.
A car near Larkhall that had been topped up weekly for a month. The leak was small and slow, but the miles run at low pressure in between had worn the inner liner enough to matter.
A flat you could hear from the pavement on a street off South Lambeth Road. Nothing was pumped and nothing was moved, so it came off the wheel exactly as it went down and was patched properly.
Not necessarily. A fast leak means something sizeable went in, but it also means you stopped straight away, which is what protects the casing. Slow leaks that get nursed for weeks are more often the ones we cannot save.
It can wait for a fitter, but it should not wait for weeks. Every top up buys more miles at the wrong pressure, and those miles are what turn a simple repair into a new tyre.
Not once you have decided to have it dealt with. Leave it soft and leave it parked. A flat tyre standing in a bay comes to no further harm.
Yes, that is where a large share of our SW9 jobs happen. The car keeps its space and the fitter works alongside it, so nothing has to be reversed out or found again later.
Then say so and it gets looked at again. A repair done properly to BS AU 159 lasts the life of the tyre, so a leak returning usually points at something else, such as the valve or the seal against the rim.
