Cold air takes up less room, so on the first properly cold night of the season a lot of dashboards light up at once. Nothing has punctured. The air that went into those tyres in the autumn has simply contracted, the pressure reading has fallen with it, and the car has noticed. That is why so many people ignore a warning light in winter, and it is also why some of them are wrong to.
The way to tell the two apart is to gauge all four. A cold night pulls every tyre down by much the same amount, so four low readings sitting close to one another is weather. One tyre noticeably below the other three is a leak, and no amount of cold accounts for it. After that, put the air back in, look for a nail head in the tread, wet the base of the valve and watch for bubbles, then come back to it later. If it has dropped again, temperature is not the answer.
Punctures do not keep opening hours. A screw picked up on London Road at eleven at night is still a screw at six the next morning, only by then you are late as well. The wheel comes off in Thornton Heath, not on a ramp in Mitcham. Nothing is towed out of Green Lane or Pollards Hill; the work finishes there. A SW16 address in Norbury and one in Thornton Heath are the same round.

Winter is when the awkward calls come in along the A23, because a tyre that has been quietly leaking all autumn finally drops past the point the car will tolerate on the coldest night of the year. Nobody wants to be dealing with that outside a terrace at midnight. Ring while the car is still parked and the odds of saving the tyre are a great deal better.
A driver checked all four before ringing and found three sitting together and one well beneath them. That is the reading that turns a maybe into a call. There was a screw in the central tread, and it was repaired the same night.
Where the car is parked safely and the tyre holds after reinflating, waiting until morning is a fair decision and we will say so. Where it softens again while you stand watching, there is a hole in it, and driving on it at dawn is what ruins the casing.
Green Lane and the climb toward Pollards Hill are no place to be kneeling beside a wheel in the dark. If a tyre is going down there, stay in the car with the hazards on and let somebody come to it with proper lighting.
A tyre can be a long way down and still look normal, particularly on low profiles. Eyes make a poor gauge. Put a proper one on all four and compare them against each other before deciding anything.
We run 24 hours a day, 365 days a year, and a cold night is one of our busier ones for exactly this reason. Nights are no different from days as far as the work itself goes.
Topping up is fine as a test and useless as a fix. If the tyre wants air again the following day, something is letting it out, and every mile driven soft moves the damage further from repairable.
They are, because a tyre losing air gently is usually still whole inside. Leave one for a fortnight and it stops being a puncture and turns into a casing nobody can do anything useful with.
The terraces here mostly have no off street parking and it makes no difference to how we work. The job happens at the kerb where the car sits, provided there is room to get alongside it safely.
