The present invention is a tire cutting machine comprising of a base, a body member, a drive assembly means and a cutting assembly means. The drive assembly means includes a drive power means simultaneously engaged to a pair of front drive wheels and to a pair of rear drive wheels to provide rotation thereof. The front drive wheels are coaxially mounted in close relation to one another on a front drive wheel shaft extending between a first drive assembly arm and a second drive assembly arm. The rear drive wheels are coaxially mounted in close relation to one another and to a guide wheel which is directly engaged to the drive power means. The cutting assembly means includes a cutting power means simultaneously engaged to a front cutting wheel and to a rear cutting wheel to provide rotation thereof. The cutting assembly means is mounted such that the lower arc of the front cutting wheel passes between the upper arcs of the front drive wheels to form a front cutting assembly and, similarly, the lower arc of the rear cutting wheel passes between the upper arcs of the rear drive wheels to form a rear cutting assembly. In operation, a scrap tire, or a portion thereof, is passed between a cutting wheel and the corresponding drive wheels thereby cutting the tire. The front cutting assembly may be used to provide transverse cuts across the tire material or the tire material may be manipulated to provide decorative cuts or various shaped portions for practical or aesthetic uses. The rear cutting assembly is used primarily to cut strips of tire material, primarily of the tread portion of a scrap tire, and includes an adjustable guide to control the width of such strips.
