A device and technique for processing tires on site includes penetrating the tire with an array of spikes to provide a multiplicity of pinholes dispersed about the tread surface. The pinholes, thereby eliminating the risk of blisters. The size and quantity of the pinholes is calibrated to provide a path for the escape of gas entrapped in the tire material during the manufacturing process, without significantly affecting the performance of strength of the tire. The pattern of pinholes provides a ready path for gas to escape as the tire is heated during use, without the risk of blistering that plagues the typical racing tire. In one embodiment of the invention, the tire is rotatably supported to contact a tire preparation element that includes a plurality of spikes configured to smoothly penetrate the tire rubber. In one feature, the spikes can be heated to facilitate penetration of the tire material, particularly high durometer materials. A drive roller, having a manual crank, can also be provided that frictionally engages the tire to rotate the tire by manipulation of the crank. In another embodiment, a plate is provided onto which the tire can be rolled or driven. The plate includes a multiplicity of spikes projecting upward therefrom, each spike configured to penetrate the tire material.
