MikeTake the wheel off and dunk it in water to check for leaks. Wait until the wife's out and use the bath 😆There's only a problem if there is then no obvious leak, but at least you'll be sure it's not a tiny puncture.Tyres on nicked or bent rims will retain air during warm weather, but often leak in lower temperatures. Effective psi loss of 1 lb. per 10 degrees drop in temp is normal, regardless of any other problems.If you have alloy wheels, what can happen over time is that the piant/laquer starts to peel from the wheel itself and the air actually leaks between the laquer and the wheel. Take the tyre off the rim and clean the bead and the lip of the wheel up.If the tyre/rim bond is compromised, usually from hitting a pothole a bit hard, you'll lose a few psi each night. Solution in this case is also to take the tyre off, buff and polish the rim and refit.Otherwise, chuck a tube in and see if that sorts it.CheersGarry
