How long the tyre took to go down is the most useful thing you can tell us on the phone, and hardly anybody thinks to. A tyre that was firm last night and flat at seven this morning has a leak you could cover with a pinhead. Something is in the tread and still plugging its own hole, or the valve is weeping.
A tyre that went from normal to flat in the time it took to reach the next junction is a different animal. That hole is big enough to see, and it usually means something tore the rubber rather than pierced it: a large object, a kerb strike on the sidewall, or the bead unseating in a pothole. The odds of a repair drop sharply.
The slow one is the one that does the damage, oddly enough, because a slow leak lets you carry on driving without ever forcing you to stop. Losses found in the morning are the best version of this. The car has stood still, the casing is intact, and the repair is straightforward at five o'clock.
It is worth saying plainly what "24 hours" covers, because the phrase gets used loosely. It means the phone is answered at any hour of any day; it means a van is dispatched rather than an appointment offered; and it means the work is finished on site, whether that is a proper repair or a replacement fitted and balanced. Weekends, bank holidays and the small hours are all in. Whether the car sits on a drive in South Wimbledon or has stopped somewhere less convenient, the service is the same. Right across Greater London, for cars, SUVs and 4x4s.

Most of the calls we take between midnight and dawn here are morning discoveries rather than roadside emergencies: a car on a drive off Kingston Road, a car parked out at Raynes Park, a car on a residential street below the Village. Nothing has been driven on, which is why those tyres so often go back on repaired.
A commuter off Kingston Road found a tyre flat on the drive before an early start. A roofing screw was still sitting in the crown, sealed around itself all night. Central band, casing untouched, repaired and rebalanced before the traffic built.
A driver near Raynes Park felt the car go heavy and was flat before the next junction. The sidewall had taken a kerb going into a parking space earlier that evening and had finally split. Nothing about that is repairable.
A tyre topped up every couple of days for two weeks came off the rim with the inner liner rubbed away in patches and the shoulders cooked. The original puncture was a nail in the middle of the tread.
Because it narrows the cause before we arrive and tells us what to bring. A slow loss overnight is usually a small object or a valve, and very often repairable. A rapid deflation points at a tear or a sidewall.
You can, and it is the decision that turns cheap jobs into expensive ones. The leak is still there, the tyre goes soft again on the way, and a few miles run soft in traffic will ruin a repairable casing.
If the car is needed at seven, yes. Working on it while it is still standing on the drive is the best condition it will ever be in, and there is no premium on the price for the hour.
The valve core, the seal where the tyre meets the rim, or a small object that has fallen out and left its hole behind. All three are found the same way, which is with the tyre off the wheel.
