A pneumatic tire includes a decorative area 11 provided on a sidewall surface 10, in which three kinds of planes 21, 22, and 23 with different inclinations with respect to a profile surface 20 are tightly arranged in the decorative area 11, two kinds of planes 21, 22, or 23 from the three kinds of planes 21, 22, and 23 are aligned in a first direction to make a pair, plural kinds of pairs with different combinations are aligned in a second direction, and boundaries 24 between each two planes 21, 22, or 23 aligned in the first direction are shifted in the first direction between the pairs adjacent in the second direction.

A tire includes a tread portion including a ground contact surface, a first rubber layer made of a first cap rubber forming part of the ground contact surface, a second rubber layer made of a second cap rubber disposed radially inwardly of the first rubber layer, and at least one groove portion opening to the ground contact surface. The first cap rubber has a loss tangent tan δ1, and the second cap rubber has a loss tangent tan δ2 greater than the loss tangent tan δ1. The groove portion includes a first indicator in which a bottom of the groove portion locally raises, the first indicator having an outer surface in a tire radial direction. The radially outer surface of the first indicator substantially coincides with a first wear line that is parallel to the ground contact surface and passes through a radially outer surface of the second rubber layer.

A wheel component for sports and racing bicycles with an annular tire and a central tread surface, which in proper use in straight-ahead travel on a plane ground circumferentially makes contact with the surface of the ground, and which opens up a central longitudinal sectional plane. Planar aero elements are configured on the surface of the annular tire, laterally spaced apart from the longitudinal sectional plane. The aero elements are configured as depressions in the surface of the tire and are disposed on the side surfaces and define angular bands rotating on the side surfaces. The surface proportion of the aero elements to the surface of an angular band is larger than 5% and less than 25%.

The invention relates to a polymer product, preferably a vehicle tire (1) with sidewalls (2), comprising a photorealistic representation (3) on the outer surface of the polymer product (2), wherein the photorealistic representation consists of the combination of a structure with a relief (5) of the representation, wherein the structure has elevations (7) and depressions (6) and wherein the relief (5) is a depth chart of the representation that is preferably produced on the basis of grayscale values of a photo and has up to 256 gradations of depth in such a way that the relief (5) fills the depressions (6) of the structure to different heights according to the grayscale value.

For generation of a photorealistic representation (3), the structure is an undirected texture (4) composed of elevations (7) and depressions (6).

A tire made of rubber material includes a sidewall and a marking protruding from this sidewall. The tire has a texture, which has a plurality of strands protruding from the sidewall, these strands being distributed at a density at least equal to five strands per square millimeter (mm.sup.2), each strand having a mean cross section between 0.0007 mm.sup.2 and 0.06 mm.sup.2 and/or the texture having a plurality of substantially mutually parallel lamellae protruding from the sidewall, the spacing of the lamellae being less than or equal to 0.5 mm, each lamella having a mean width between 0.03 mm and 0.3 mm. The texture protrudes from the sidewall of the tire, and this texture surrounds all or part of the marking.

A pneumatic tire assembly includes: a tread portion including one or more traction features; a first sidewall portion coupled to the tread portion; and a first bead portion coupled to the first sidewall portion; wherein the first sidewall portion includes multiangle first tread traction features positioned proximate the tread portion.

A vehicle tire, as a rubber member, includes, on at least a part of the surface thereof, a fine ridged/grooved structure formed via transfer from a mold and having fine ridged/grooved portions arranged at a constant arrangement pitch, wherein a region in which the fine ridged/grooved structure is provided is visually recognizable by a different structural color from the colors of other regions.

A pneumatic tire has a pair of sidewall portion 3. An outer surface of at least one of the pair of sidewall portions 3 includes a decorative region 5 extending in a tire circumferential direction. In the decorative region 5, a plurality of pattern elements 8 are arranged, whereby the decorative region 5 includes a plurality of circumferential pattern lines 6 in each of which the pattern elements 8 are aligned in the tire circumferential direction, and a plurality of radial pattern lines 7 in each of which the pattern elements 8 are aligned in a tire radial direction. In each circumferential pattern line 6, lengths in the tire circumferential direction of the pattern elements 8 are changed in the tire circumferential direction. In each radial pattern line 7, lengths in the tire radial direction of the pattern elements 8 are changed in the tire radial direction.

A pneumatic tire exerts an excellent blurring effect on irregularities resulting from a boundary between members in a sidewall portion. A pneumatic tire includes a serration portion formed by providing multiple basic ridges side by side at intervals in a tire circumferential direction on a surface of a sidewall portion, and multiple sub-ridges extending in a direction crossing the basic ridges and shorter than the basic ridges, which are provided without coupling the basic ridges neighboring each other.
