Those are Mickeys. (And at least 4 or 5 other companies also make "drag radials").
E.T. Street SS have a somewhat like normal tread, but not much depth, and like all drag radials, will wear out quickly daily driven.
E.T. Street R have minimal tread, a more aggressive compound, more race tire than the SS.
E.T. Street Pro have NO tread, only a divot here and there, and are pure race tires for 4 second 1/8 mile drag racers. (I'm not anywhere NEAR fast, but I bought the pros, cause I needed a big radial to fill the wheelwells of my Opel.)
