Quite often the tyre is innocent. The valve is a rubber component with a metal core inside it, and both parts age. Rubber stems perish where they bend over the rim, particularly after years of kerb-side parking and temperature swings, and they crack at the base where you cannot see them. The core is a tiny spring-loaded item that seals every time you take the airline off, and a speck of grit under its seat will let air past indefinitely.
Diagnosing this properly takes a minute and saves a lot of money, because a valve costs almost nothing and a tyre does not. A drop of soapy water on the valve will bubble if the core is leaking. A leak at the base of the stem needs the tyre off the rim to see. We check both before condemning anything, and a stem is replaced as a matter of course whenever a tyre comes off in our hands.
The temptation at 1am is to pump it up and deal with it tomorrow. We come out at that hour in West Molesey, get the wheel off and inspect the tyre from the inside before deciding anything, then repair to British Standard where the damage qualifies. Level in East Molesey, sloping in Molesey Park: we set the car straight first. Underground parking in Hurst Park or Kent Town is worth flagging.

Cars here sit outside through everything the river throws at them, and years of damp and temperature swing are exactly what finishes a rubber valve stem. If a tyre has been going down slowly for months and nobody has ever taken it off the rim, the valve is well worth ruling out before another puncture hunt starts.
The core is not sealing, usually because of grit or age. It takes seconds to replace and it explains a slow leak that has had somebody chasing punctures for weeks.
Years of flexing over the rim edge and temperature cycling split the rubber where it is hidden. It is invisible with the tyre on and obvious with it off.
Worth doing there and then. A valve is a two minute job at midnight and the alternative is another week of topping up and hoping.
Very easily, and it is one of the most commonly missed causes. The symptoms are identical to a small tread puncture from the driver's seat.
Soapy water on the valve with the cap off. If it bubbles steadily, the core is leaking. A leak deeper down at the base of the stem will not show that way.
As standard whenever the tyre comes off the rim. Fitting a new tyre onto a ten year old rubber stem is asking for a return visit.
Every night of the year, including Bridge Road, Kent Town and the roads out towards East Molesey. Typical arrival is 30 to 60 minutes.
No. The quote you get before we set off is what you pay, whatever the hour.
