From the Losi Website " These semi-slick tires completely change the look and handling of your PROMOTO-MX, providing superior grip on asphalt and other smooth surfaces. This allows you to carve better apexes, pop better wheelies, and rocket around your track, street, driveway, or parking lot with precision and style."

We shall see about that, I have heard a lot of talk about clearance issues but have not tested them for myself, so I finally got the front tire in, and its time to go rip the Losi PRomoto MX around the Parking lot.
