PNEUMATIC TIRE AND ITS DISMANTLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a dismantling method of a pneumatic tire which facilitates separation of a rubber layer and is excellent in recyclability and retreadability. SOLUTION: At least one piece of cord C is arranged in a planar state in a boundary of a tread rubber layer 2, a partition layer 4 interposing a rubber part between the cords C, and a separation auxiliary layer 5 made of a material having higher Young's modulus than that of the peripheral rubber is laminated on the edge part of the partition layer 4. The tread rubber layer 2 adjacent to the partition layer 4 is separated by drawing the cord C of the partition layer 4 in the planar direction of the partition layer 4, and sequentially cutting the rubber part interposed between the cords C.
