For bashing in the mud or loose dirt, the HobbyStar Sling-Star tire is ideal with a simple yet highly effective tread design. The aggressive paddle-inspired design digs deep into the dirt for intense, mud-slinging traction and looks mean while doing it. Medium rubber compound provides excellent traction and wear characteristics. Their 4.5" tall design makes them perfect for vehicles that don't require a full-size monster truck tire (like the Traxxas Rustler). Mounted on stylish HobbyStar 12mm hex Web wheels, they include foam and come un-glued. One set of 2 tires/wheels.
