My front right tire was patched about two months ago due to a nail driving straight into it. Ever since, the ride as been horrible. I check my pressure on a regular basis (less than i should), and about two weeks ago after the car sitting for a day, I read 24 pounds, down from 32, so I filled the tire. Well it still rides bad, so I checked the pressure again. Tonight I read 45 pounds. Would the tire still be hot enough to cause the increased pressure? (has been sitting for about four hours, keep in mind it is arizona).
