    Tires and Pressure

    Hey Guys, just inquiring about the tire size and load specification.

    On my 98 T/A... I have stock rims with tire size 245 50 16.. However on my door it says 235 55 16 and a pressure of 30 psi. There is no mention of this size in the manual...only the 245 50 16 which it says if you are driving more than 100 mph then to use 38-44 psi.. Trying to figure out the correct pressure for my 245 50 16's. Also, I don't have the original manual but have downloaded a version online...not sure if each manual is specific to each car..idk..Can anyone help me out with this....Thanks.

    Well, 275/40/17's for me.

    But I run my 225/50/16's on the Grand Am at that as well. Probably closer to the 35 mark.

    Tire pressure isn't going to change much with different tire/wheel sizes.
    My old 16's I ran 30-32 psi my 18's I run the same 30-32psi.
    It's more of a comfort factor aswell if you run over 35psi the car will ride harder (harsher impacts)

    Same here, except I run 32psi in the front tires and 30psi in the rear tires.
    If you have really good roads where you drive fill free to add 4-5 psi to the above tire pressures front, and rear.

    I run 32psi up front, 30psi out back. I used to run 35/33 on my old Camaro (245,50,16) and this wore a bald stripe prematurely in the middle of the tires.

    Whatever pressure is listed in the door jam is correct. Also, that should be the pressure when the tires are "cold". I usually over fill the tires (slightly) when I'm at the gas station, and then re-adjust the pressure the next morning before I start driving (while they are still cold).
