Tires lose pressure with temp change.

cbarlow

Every time the temperature drops even 10 degrees, I have to air up my tires. I have Cooper Touring [255/60R19] tires. I have had them checked multiple times; the tires have been taken off and resealed, the valves have been replaced but they can't find a reason for it. Does anyone else have this issue? I need to get new tires and I don't want to have to go thru this issue with another set of tires. Thanks for any help you might have on this issue.

Air expands as temperature increases, and contracts as it decreases.

kyfdx: Yes it does, but it doesn't cause tire pressure to drop 10 lbs.
