Door Jam Label Tire Pressures for Grand Sport Coupe

[Rich96c4ce]

Hi, Grand Sport Lovers,
I just changed from 255/285 to 275/315 tires. I would like to know the front and rear tire pressures recommended by GM.
Thanks,
Rich

Look at the max on the tire.........then keep em' at a couple under........example my EMT's are 44#'s max........I have kept em' at 40#'s............and have been doing this since my 93'. Even the Michelin Pilots ran 40#'s. This is just a setting for daily driving.....if you doing other things with molded plastic.......you will need to consider other pressures. These settings are used for longevity of the tires....creature comfort would be 36 front 38 rear.....as always IMHO.
