PNEUMATIC TIRE AND MANUFACTURING METHOD THEREFOR

摘要

Cracking and splitting at the interface between black rubber and white rubber is suppressed, and the durability of raised patterns is improved. In a pneumatic tire (1) having a raised pattern (9) of protruding graphics or symbols, the raised pattern (9) has a white rubber portion (11) exposed on the outside surface, and a black rubber portion (12) in which the white rubber portion (11) has been arranged in the axial direction of the tire. An outside surface layer (16) is provided on the outside of the black rubber portion (12) in the axial direction of the tire in which a black rubber strip (14) has been wound at helical pitch P1 from 0.50 to 0.80 times width w1. An inner surface layer (18) is provided on the inside of the white rubber portion (11) in the axial direction of the tire facing the outer surface layer (16) in which a white rubber strip (15) is wound at helical pitch P2 from 0.50 to 0.80 times width w2.
