The temp rise you describe is normal. As the tires heat up the air they contain increases in pressure. On hot days you will see an even higher rise in temp as you drive. I run 28lbs in mine cold, don't know about everybody else. I'm not as interested in wear life as I am in ride and traction gain, 28 lbs. seems to be about right for me.

Allen noted in a previous thread that 31 was the proper cold pressure.

Not sure where it was, but I do remember it.
Should be a sticker inside the driver's door jamb. I think mine says 30.
