I am not sure what you are calling a real street tire but a drag radial definately is. They have tread that looks like most other street tires and are a steel belted radial that is Z rated. My DRs stood up to 15,000 miles of abuse without rotating which is over half the life of my KDW's or any other tire I have had on this car that were rotated every 5000 miles. In addition they are DOT approved so you need to rethink what you call a real street tire. I think but am not sure that Brad N had 60' times only slightly slower than my 2.04's on a non drag radial street tire. Also for what it is worth traction is still very limited with drag radials, it is very difficult to be consistent my car still suffers from bogging if you launch to low or spinning if you launch to high.
