Tyre pressure in winter

[TimothyN]

I have never before had a car which reports the tyre pressure (as opposed to just screaming when it drops.)

So I have never before seen how much lower are the pressures in cold weather. It's basic physics, obviously, and no real surprise, but it's more salient when thrust in your face.

So, does the team think that we should pump up the tyres to 37 in winter, or just let them be at the 35 they have fallen to?

Reset them to 37psi

Leave them the air in the tyres contract when cold given the false reading check the tyres when you've run them but give half an hour or so before checking.and if they are below the recommended setting inflate.

You should check them every month when the tyres are cold and adjust the pressure accordingly.

Having said that a drop of 5% isn't much of a problem unless you are doing a long journey and/or at motorway speeds. Some owners are running their cars at 35 psi to improve the ride comfort.

I think it depends on the definition of cold it has been minus 6 where I live so definitely going to get false readings hence why I said drive the car for half an hour then let it sit for half an hour and check again with a tyre pressure gauge, don't rely on the computer settings in the car they are never correct.
