ABSTRACT:
The present invention is directed to an apparatus which is inserted between the inner walls of pneumatic tire casings mounted on a dual wheel assembly. The apparatus is formed of one or more annular elements having an outer circumferential face, an inner circumferential face and left and right sidewalls. The major portion of each of the left and right sidewalls is substantially planar. At least one of the left and right sidewalls has a plurality of cooling grooves. The cooling grooves extend from the outer circumferential face to the inner circumferential face. The cooling grooves are substantially U-shaped and have a uniform depth throughout their entire length. The cooling grooves are uniformly spaced about the circumference of the annular member. The cooling grooves readily dissipate the heat which is generated by the brakes and the flexing of the tire casings when placed under a load. The outer circumferential face of the annular member is positioned intermediate the flex point of the pneumatic tire casings and the treads thereof.
