Do alloy wheels "leak" air?
I've never had the "luxury" (?!) of having alloy wheels on a car before and have found that I have to keep topping up the air in all 4 tyres every few days.
At first I thought it was the airline at the local garage being out of calibration, but after using several different garages, I have the same symptoms.
It normally only drops 2-4 bar, but on one occassion it had dropped by
10bar which made for an interesting drive!The weather has been very changeable of late here in the frozen North, but I wouldn't have expected such a dramatic drop in tyre pressure.
