I know these aren't the ideal tire for the purpose, but I just want to get the tire pressures as good as they can be.
295x30x18 and 245x35x18 2500# Yes it's my V8 car. The current situation at hand is our Enduro autocross. It's about a 4+ minute run of 5 laps. (unless you're Britain Smith, then it's closer to 3:30...) I would also like to know how this changes with a normal Autocross of about 1 minute and then again how it changes with a 20 minute road course. Thanks Dan Attached thumbnail(s) |

Some years back, I had a conversation with one of the engineers at Hoosier regarding a tire pressure starting point for non DOT race tires. He advised to run pressures at 1% of the vehicle weight. From there, adjust the pressures to attain best temp profiles when combined with the proper suspension adjustments.
