Ya Dave Im not sure about them either. A lot of people use them but I dont know anyone who does. Its not a radial and would probably do ok on the street but im not sure. I just want a street/strip front so I wont have to switch fronts. I want slicks for the strip and I have an extra set of wheels for that but dont want to have to change all four to go to the track. Im sure there is a suitable front tire for what im looking for but am not sure the MT sportsman is it.
