ABSTRACT:
A tire grinding apparatus includes at least one support arm pivotally connected to a base. A pair of grinding wheels are rotatably carried by the support arm and are adapted to engage the outer surface of a tire. The grinding wheels are disposed such that one of the grinding wheels is a leading grinding wheel and the other is a trailing grinding wheel. The grinding wheels rotate in opposite directions. The grinding wheels are partially disposed in a hood that is in fluid communication with a vacuum source. A source of pressurized air is in fluid communication with a blower head that is disposed between the grinding wheels such that it directs pressurized air against the surface of the tire being ground. The pressurized air removes dust from the tread grooves and sipes of the tire where it is collected by the hood and removed from the hood from the vacuum system. The position of the trailing wheel is adjustable with respect to the leading grinding wheel and the support arm. The position of the support arm is adjustable with respect to the tire. The tire grinding apparatus provides an improved surface finish by utilizing the two grinding wheels and removes a substantial amount of the dust from the tread groves in sipes of the tire.
