Abstract: A pneumatic tire can include a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass. At least one of the sidewall portions can include a first sidewall rubber. The first sidewall rubber can include a base rubber layer, a different color rubber layer, and a barrier rubber layer. The base rubber layer can be in contact with the carcass. At least a part of the different color rubber layer can be exposed in the outer surface of the at least one of the sidewall portions. The barrier rubber layer can be arranged between the different color rubber layer and the base rubber layer. The barrier rubber layer can have a rubber compounding to suppress migration of rubber compounding agents on the base rubber layer side to the different color rubber layer. The barrier rubber layer can have a thickness of 1.0 mm or less.

Abstract: An aspect of the present invention relates to a tire comprising a sidewall, the sidewall having a surface comprising a surface portion including a hexagonal textured base pattern repeated over the surface portion so as to form a periodic textured pattern providing a high contrast to the surface portion. The hexagonal textured base pattern comprises protrusions and recesses, the protrusions and the recesses of the repeated textured base pattern cooperating to form respective lineal features extending over at least two of the repeated hexagonal textured base patterns.

Abstract: To provide a pneumatic tire that provides improved driving performance on unpaved roads and cut resistance. High blocks and low blocks with different raised heights are provided as side blocks provided in a side region. One of the high blocks and one of the low blocks adjacent to each other in a tire circumferential direction are defined as a block pair. The high block and the low block included in the block pair are partially in contact with each other. Thus, a side groove between these blocks is a closed groove. In each block pair, a pair of contour lines (a first linear portion, a second linear portion, and a third linear portion) define edges on both sides, in the tire circumferential direction, of a top surface of each of the high block and the low block.

Abstract: A pneumatic includes a pair of sidewall portions. At least one of the sidewall portions is provided on an outer surface thereof with a first protruding portion arranged on an outer side in a tire radial direction and a second protruding portion arranged on a radially inner side. Both protruding portions are formed so as to be convex outward in a tire axial direction. The second protruding portion has a protruding apex surface formed of a different colored rubber material having a different color from an outer surface of the first protruding portion. A distance in the tire radial direction between an inner edge in the tire radial direction of the first protruding portion and an outer edge in the tire radial direction of the second protruding portion is 40% or more and 220% or less of a length in the tire radial direction of the second protruding portion.

Abstract: A pneumatic tire can include a tread portion, a pair of sidewall portions, bead portions, and a carcass. At least one sidewall portion can include a first sidewall rubber arranged outside the carcass in a tire axial direction. The first sidewall rubber can include a different color rubber layer and a barrier rubber layer. The different color rubber layer can have a color different from a basic color of an outer surface of the at least one sidewall portion. At least a part of the different color rubber layer can be exposed in the outer surface of the at least one sidewall portion. The barrier rubber layer can be arranged between the different color rubber layer and the carcass. The barrier rubber layer can include a first portion having a rubber compounding to suppress migration of rubber compounding agents on the carcass side to the different color rubber layer.

Abstract: A protrusion portion (110) of a pneumatic tire is formed by a plurality of protrusion parts (111) extended along a tire circumferential direction. The protrusion parts (111) are arranged with predetermined gaps therebetween so as to form a circle along the tire circumferential direction. A length (S1) of the protrusion part (111) in the tire circumferential direction is larger than a maximum width (W1) of the protrusion part (111) in a tire radial direction. In a tire side view, a narrow groove (200) extended along the tire circumferential direction is formed on a surface (111s) of the protrusion part (111).
