Drag radials are considered a street tire. The quickest/fastest guys in the NMRA DR class are running in the mid to high 8 sec zone... pulling the front wheels, of course
Anyone ever see the pic of Big Daddy Dwayne Gutridge doing a wheelstand on DR's... you can see daylight between one of the rear tires as he's standing it on the bumper in one of the still shots!
...on street legal tires!
Regular ole radial treads (which is probably what you were talking about) ...fugeta bout it!!!!
