Been running Hoosier's 30 x 10.5 radial slick on my nose heavy 3880 lb. BB Chevelle since the 2000 season using 3 pairs a season, pulling them off at 75 passes and typically aired to 18 psi.
Have gone 100+ passes on a set and I've run them with as much as 20 psi.
Have gone a best of 1.28 60 foot and 1.36 60 foot breaking the beam with the back tires.
My rule of thumb is to start at 5 psi more than what you ran with bias slicks.
