PURPOSE:To provide a manufacturing method of pneumatic tire which can produce a pneumatic tire of an excellent uniformity. CONSTITUTION:Slit grooves 30 for rigidity reducing are formed on the second block 26A with the longest circumferential size and on the second block 26B with the secondly largest circumferential size, of the second block 26 at the shoulder side of a high ground pressure. As a result, the difference of the rigidity in the circumferential direction between the larger block and the smaller block is eliminated, and the uniformity of a pneumatic tire can be improved. |
