Mickey Thompson Mickey Thompson offers the ET Street Radial, a DOT-approved, street-legal drag radial with a soft compound and directional tread pattern for maximum traction. The ET Street is best for auto trans cars according to Mickey Thompson, and is available in 15- to 17-inch rim diameters. The ET Street Radial II, designed for larger wheel sizes and big brake packages is available in 14- to 18-inch rim diameters. These tires are often the choice of street cars with big horsepower numbers. Of course, Mickey Thompson still offers its famous Sportsman Pro bias-ply DOT tires in nearly a dozen 15-inch diameters with matching front tires too.
