I have a pump gas street 3400 lbs. Duster that has gone 1:43 60. ft times on 315x60x15 M/T ET Street Radials at 10:34 and 128.6 MPH, no power adders It is a ladder bar car with coil overs and a track bar, I also have a set of 13:50x30x15 ET Street bias ply tires on the same size rims as the radials. The radials will run quicker and faster on a good track versus the bias ply tires, the bias ply tires will drive easier on a bad track and not spin at the top of first gear like the radials will on a bad track I have found that after driving the radails on the street, the first pass, no matter what kind of burn out I do , will spin bad, the second pass will hook a lot better no matter on the burn out procedures I do run between 17.5 lbs and 22 lbs in the radails and 9.5 to 11.0 lbs on the bias plys on ten inch wide rims. IHTHs BTW, if you run the air pressure to low in the radials they will not hook
