drag radial tire pressure

[68 C-10 KID]

I was told by the outlaw guys that if you have to run much lower that 15-17 psi you need to do some suspension tuning.

At the track you want to run the pressure as high as you can while maintaining traction. Usually radials like a little bit higher pressure than bias-ply's do. I've never used hoosier DR's, but with mickey's I usually start around 22psi and start working your way down from there. Remember track prep and suspension setup are much bigger factors to traction when running radials.....they're not near as forgiving as bias-ply's.

15-18 at the lowest . A little change makes a big difference . You need a good low pressure gauge and take notes on your time slips or log book to study later .
