Pressures have to be read cold, and hardly anybody does. A tyre warms up as it is driven, the air inside expands, and the gauge reads several pounds higher than the tyre is actually set to. Check at a forecourt after a twenty minute drive and you may see a perfectly reassuring number on a tyre that is genuinely under-inflated. Then you drive away, it cools, and you are back where you started.
Cold means the car has been standing for a couple of hours, or has covered less than a mile or two. That is why the useful check is on the driveway before you set off rather than at a garage after a run. It matters for spotting a slow leak too, because comparing a warm reading with the plate figure tells you nothing. When we come out, the reading is taken on a tyre that has not been driven, and if it has been, we account for it.
Urgent does not mean rushed, and it should not mean a worse repair. The method is the same whether you have all afternoon or twenty minutes: wheel off, tyre off the rim, casing inspected from the inside, an internal plug-patch fitted only where BS AU 159 permits one, then rebalanced and pressure-set. From Willesden Green to Roundwood, typical arrival is 30 to 60 minutes with a live ETA. Same tools in Dollis Hill as in Roundwood, same on every call. The wheel comes off in Roundwood, not on a ramp in Cricklewood.

Most people around Willesden top up at a forecourt after a drive through the High Road traffic, which is exactly the moment the readings are least useful. If a tyre has been quietly going soft, the check that finds it is done on the street outside the house before the car moves, and that is also the check worth doing before you ring us.
Warm air reads high. A tyre that shows the right number after a drive can be several pounds down once it has cooled overnight.
Worse than not checking at all, because the tyre is now deliberately under-inflated once it cools. If you must set them warm, add a couple of pounds and re-check cold.
Comparing warm numbers with the plate figure masks a genuine loss for weeks. It only shows up when somebody checks the tyres cold.
After the car has stood for a couple of hours, or before it has covered more than a mile or so. First thing in the morning is the ideal time.
Several pounds between a cold tyre and one that has been driven hard for half an hour. Enough to hide an under-inflated tyre completely.
Allow a couple of pounds above the plate figure and check again cold when you can. It is a workaround rather than a solution.
Yes, all four against the plate in the door shut, and we will tell you the actual numbers rather than a general impression.
Typical arrival is 30 to 60 minutes, and we come to the permit bay, driveway or kerb where the car is already parked.
