Cold weather produces a wave of calls that turn out not to be punctures at all. Air contracts as it cools, and the rule of thumb is roughly one pound per square inch for every ten degrees the temperature falls. A car that was set to the right pressure on a mild October afternoon can be several pounds down on a hard frost in January with absolutely nothing wrong with it, and on a car with pressure sensors the warning light comes on and everybody assumes the worst.
The way to tell them apart is simple enough. A temperature drop affects all four tyres more or less equally. A puncture affects one. If three are a little low and the fourth is a lot low, you have a leak. If all four came down together overnight and the frost was hard, you probably have physics. We will tell you which it is rather than sell you a repair you do not need.
A train to catch is a hard deadline in a way that most things are not. You cannot negotiate with a timetable, and a puncture found twenty minutes before you meant to leave the house in Sherrards does not care. The wheel comes off in Hatfield Hyde, not on a ramp in Hertford. Nothing is towed out of Peartree or Woodhall; the work finishes there.

Cars parked outside overnight around Handside and Sherrards take the full temperature swing, and a hard frost will drop every tyre on the street a few pounds. The check that settles it costs nothing: read all four and compare. One outlier is a job for us, and four even readings on a cold morning usually just want air.
Very common in a cold snap and often nothing more than the air contracting. Worth checking properly rather than ignoring, because the light cannot tell the difference either.
That is a leak. Even pressure loss across all four points at temperature, and a single odd one out points at something in the tyre or at the valve.
Temperature does not keep taking pressure out week after week. Repeated loss on the same corner is a puncture and it is worth finding before it decides its own moment.
Yes, a few pounds across all four as the temperature drops. What is not normal is one tyre losing noticeably more than the others.
Top them up to the plate figure by all means, then watch. If one is down again in a few days, that is the one worth calling us about.
Often, from the numbers. Read us what all four are reading and how cold it has been, and we can usually say whether it is worth a callout.
Typically 30 to 60 minutes anywhere in Welwyn Garden City, including Shire Park, the station and the residential districts.
We would rather sort it on the phone than travel for nothing. If we do come out and the tyres are sound, you get told that and no work is invented.
