Patent ID: 8720512

Claim:
A pneumatic tire comprising: a plurality of sidewall parts and a tread portion between the sidewall parts, at least one of the sidewall parts including a sidewall surface having a non-patterned portion and a pattern extending in a tire circumferential direction that is visually differentiated from surrounding regions of the sidewall surface by an irregularity or reflectance properties of light; the pattern includes a plurality of linear protrusions or grooves that extend in a wave shape in the tire circumferential direction while deflecting in a tire radial direction with a period of λ 1 , the linear protrusions or grooves have intervals in the tire radial direction and are non-intersecting with each other, and a maximum amplitude A 1 of the linear protrusions or grooves in the tire radial direction and the period λ 1 have a relationship such that 0.1≦A 2 /λ 1 ≦1.5; and outer and inner circumferences of the pattern in the tire radial direction are formed by the plurality of linear protrusions or grooves to extend in the wave shape in the tire circumferential direction, the outer circumference of the pattern defining an outer circumference boundary between the pattern and the non-patterned portion and the inner circumference of the pattern defining an inner circumference boundary between the pattern and the non-patterned portion, and a width of the plurality of linear protrusions or grooves is formed so as to increase in the tire radial direction approaching an outermost position or an innermost position of the tire radial direction of the plurality of protrusions or grooves, so as to decrease in the tire radial direction approaching a center position between the outermost and innermost positions.
