Take a look at the M/T ET streets(bias plys) that are the same size as the 315x60x15 ET Street Radials, they worked great on my old pump gas Duster
That car ran 10.42 at 126 MPH on the ET street bias ply tires and 10.31 at 127 MPH on the ET street radials corked up on Oregon 91 octane pump swill
The radials sucked horribly on a bad track, not so with the bias plys
