A tire grinding apparatus (10) comprising at least one support arm (30) pivotally connected to a base; and a leading and trailing of grinding wheels (40, 42) rotatably carried by the spport arm (30) to engage the outer surface (12) of a tire (14). The grinding wheels rotate in opposite directions and are partially diposed in a hood (90) that is in fluid communication with a vacuum source (86). A source of pressurized air (82) is in fluid communication with a blower (80) that is disposed between the grinding wheels such that it directs pressurized air against the surface of the tire being ground so as to remove dust from tread grooves (18) and sipes (20) of the tire. The position of the trailing wheel (42) is adjustable with respect to the leading wheel (40) and the support arm (30). The position of the support arm (30) is also adjustable with respect to the tire (14).

Les meules tournent en sens inverse et sont partiellement disposées à l'intérieur d'une enceinte (90) en communication fluidique avec une source d'aspiration (86). Une source d'air comprimé (82), en communication fluidique avec un ventilateur (80) disposé entre les meules, dirige l'air comprimé contre la surface du pneu en train d'être rectifié, de façon à chasser la poussière des rainures (18) et les lamelles (20) dudit pneu.
