my girlfriend has a saturn SL2 (95) and is running KUHMO 732 PLUS tires. the manual says to defer to the specifics on the side of the tire for pressure info, but all it lists on the sidewall is max pressure. after a little internet scouring, it seems 30 lbs front and 28 rear is suggested. she currently has 33 front and 32 rear. any danger in this? any suggestions? should it be higher in the cold weather? thanx.
