Just saw this... http://www.tirerack.com/tires/tires.jsp?tireMake=Hoosier&tireModel=R6 Hope is isn't old news.
WARNING: DOT labeled Hoosier Racing Tires meet Department of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate any Hoosier Racing Tire including DOT tires on public roads. The prohibited use of Hoosier Racing Tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in a vehicle crash and possibly injury or death.
I think that disclaimer is just similar to what you would get for ET streets. Just don't drive them in the rain and you should be fine.
Old news.
These may be good for track days when combined with a set of Copperhead wheels - check with Parts Rack.
Kumhos are much better on the street than cups.
