• forming, in the bright-colored portion, a colored layer as an outer layer of the white-colored layer by applying a paint having a color different from the black color and the white color, the bright-colored layer having a thickness less than a thickness of the white-colored layer,
• wherein a boundary line between the bright-colored portion and the dark-colored portion has a first portion that is inclined with respect to a tire circumferential direction and a second portion that extends along the tire circumferential direction, and the first portion has a total length that is greater than a total length of the second portion,
• the white-colored layer also has a thickness in the range from 0.01 to 0.3 mm, and
• the colored layer has a thickness is 0.15 mm or less.
