this invention is a belt from the occurrence of heat in the shortest time to external cooling will be part of the world, and the action of a company and can prevent the durability to want to know about them. ud0c0uc774uc5b4uc5d0.;in the tire shoulder part (25) of accumulated heat in the external radiation, in order to let the segment (35) on the thermal conductivity of the heat release sheet (10) and the protection sheet (10) installed at the outside of the contact hole 11 is formed to)uc744 (cooling structure is provided. on the sea, the protection degree of the results to a certain extent, the cooling effect can be increased, and a is the degree of cooling effect cannot be obtained.;this invention is a multi layer (11), the eagle band (12) and (13), (14) that is installed to the tire, the tire shoulder part (10) and the internal shoulder in the heat accumulation is the external cooling of the cooling at home (2) you ud0a4ub418 form, the cooling groove (2) of the inside diameter is 2.5 to 4.the scope of 5mm in the cooling groove (2), the depth of the maximum amplitude as the second end of the belt (12), and a step (1) ow edge meet point (c) and the horizontal distance (a) of the 2 / 3 more than the is not in the scope of the city ud0a4uba70, cooling groove (2) with the upper jig in order to form the image to achieve, each cooling groove (2) is close to the depth of the groove and each different form of structure, the shoulder department, the accumulated heat of the little one on mandatory emission according to the property and the change of... microwave radiation a method to prevent the tire durability can be effective.
