Check your air pressure!

I went in for an oil change once, had tires at set to 43-44psi just to keep them below the max psi rating.... dealership told me the tires were at 49psi. I was a bit shocked, but then stated that the weather was much colder when I set them to 43-44, and that maybe the 35F increase in heat was to blame.

Guy said that temp differences would only make a change of 1 or 2 psi... I don't know if I should believe him or not... I don't really care.... but the random high psi did explain why my ride had more rattling going on at the time.

Anybody know how much of a temp change it takes to increase temps by 1psi?
