What tire pressure do i run on track day next saturday at Talladega Gran Prix Race Course? Its a 1.4 mile 7 or 8 turn road race course. I have a 2010 Shelby GT500 Convertible i take out there too and top speed there is 120mph. My GTR should do about 130! I called Nissan USA today and spoke to someone in the gtr department. She didn't know what pressure to run so i called Dunlop and they didnt . The dealer didnt know either. I took it to the dealer to have the 1,000 mile service and i don't think they did anything. My Shelby runs 32psi all around with the stock tires and when i run Hoosier R6's i run 42psi. The track is all left turns but one. I run thru the right front tire before the track day ends! I hope someone can please help me with this? The sticker in the door says 29psi in all four tires. The manual says 29psi rear and 30.0-31.9. PLEASE HELP ME!!!
