I recently swapped out my 17" Bullitts for a set of like new 18" OEM Chrome Bullitts. I measured the pressure in those tires to be 37 PSI which seems a little high to me. I know on my door jam sticker there is a recommended tire pressure for my stock wheels, but what about for these new wheels? Any one have a S197 GT which came stock with the 235/50 18s who could tell me what the door jam sticker says? Thanks.
