Those really aren't true street tires, they are M&H DOT cheater slicks, not exactly a true radial street tire. They are DOT legal, but they are pretty much slicks with 2 lines in them and not very safe on the street. Most of the AWDs you see with slicks on have similar DOT slicks on like the M&Hs or Hoosier Quicktime Pros.
