    Default Air pressure questions

    I'm running Hoosier e-mod D tires. I have my stagger, now I need to know some starting air pressures.I have Rf-84" RR-85" LF-83" LR-83" . Right now I am starting at 9psi inside and 13psi on the outside.Track is a 1/4 semi banked and will get slicked off by feature time. Beadlock on RR What kind of air pressure do I need to start and what would you do at feature time? I dont have a mega motor so I'm planning on running soft tires all night. Thanks Eddie

    Don't forget to rescale it after an air change. On our late model I could add 2 lbs to the RF and LR and drop 1 lb on the LF and RR and it would gain about #200lbs of bite.
    I would suggest putting it on the scales, make changes, record the results and use it for tuning.
