Abstract
In a tire testing machine, a loadwheel is repeatedly engaged by a tire. Rubber from the tire is embedded in the grit on the surface of the loadwheel. A rotating brush is moved against the loadwheel, engaging the rotating loadwheel between testing operations to maintain the loadwheel substantially free of rubber.
