9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
I have the 17 X 7 Double Evo wheels on my vert. I keep having to put air in the tires more frequently than any other car I have had , more in cold weather. It is not due to punctures as far as I can tell. Can the TPMS sensors be causing a slow leak that is worse in cold weather? I'm pretty sure...
