A machine is shown for conditioning a tire carcass for recapping wherein the tire is rotated while the crown is rasped to size and then a feeler is dropped onto the rasped crown surface while the tire continues to rotate. The feeler rides on this rasped surface to control the application of power driven shoulder rasping means to the carcass, the shoulder rasping means being operative on the opposite sides of the feeler to condition the shoulders for further processing. Adjustable guide means are shown for directing the paths of movement of shoulder rasping means to cause them to move in a desired pattern over the respective shoulders with which each shoulder rasper is made to cooperate.
