A pneumatic tire comprises a recessed portion or a projecting portion formed on a side portion so as to constitute a mark, and a colored portion formed in at least a part of a periphery along an outer edge of the mark.

A pneumatic tire includes a surface and is rotatable about a center axis. The surface of the pneumatic tire includes a ground colored region including a surface of rubber, and an image recognition belt region including a colored region provided in a circumferential direction of the center axis.

In a tire, first and second ridge parts extending in a tire radial direction each have a central portion in the tire radial direction located on an inner side in the tire radial direction with respect to a central portion of the first ridge part in the tire radial direction are provided on an outer surface of a side wall part. A decorative area provided in an outer surface of the side wall part includes a dense area in which the first ridge part and the second ridge part face each other in the tire circumferential direction, and a sparse area in which either the first ridge parts or the second ridge parts face each other in the tire circumferential direction without interposing the other therebetween.

A tire that can achieve both desired visibility and design properties of a mark provided on a sidewall portion is provided. A tire has a mark provided on a surface of a sidewall portion so as to be raised from the surface. The mark includes a curved surface portion curved so as to project in a direction substantially perpendicular to the surface of the sidewall portion, and a flat surface portion provided on at least one side in a tire circumferential direction of the curved surface portion, and a raised height h of the flat surface portion from the surface gradually decreases with increasing distance in the tire circumferential direction from the curved surface portion.

A tire includes a pair of sidewall portions. An outer surface of at least one of the sidewall portions includes at least one concave mark recessed from a reference surface. The or each concave mark includes a bottom surface and an inner wall surface. The bottom surface includes a peripheral region and a main region. The peripheral region includes a shadow region and a non-shadow region. The shadow region and the non-shadow region are each formed with an uneven surface provided with minute protuberances. A width of the uneven surface of the non-shadow region measured in a direction perpendicular to a contour of the or each concave mark is smaller than a width of the uneven surface of the shadow region measured in a direction perpendicular to the contour.

A tire capable of showing a sufficient cooling effect on a tire side portion when a vehicle travels at a low speed. A pneumatic tire includes a projection group in a tire side portion. A gap is formed between a first projection and a second projection. A size of the gap in a tire radial direction is smaller than a size of each of the first projection and the second projection in the tire radial direction.

A tire has an outer surface comprising a decorative portion which is visible and provided with micro-protuberances at a density of from 2 to 10 micro-protuberances per 1 sq.mm, and the micro-protuberances include a recessed micro-protuberance provided at its top surface with a recess.

A tire has a visible outer surface comprising a decorative region provided with a plurality of micro-protrusions each comprising a recess and a wall portion. The wall portion surrounds the recess to form a protrusion's apex having an upper surface, and the upper surface of the wall portion comprises at least two peak points in the protruding-height direction of the micro-protrusion, at which the protruding height of the wall portion becomes local maximum.

A tire according to the present disclosure includes, on the tire outer surface, a first region including an uneven surface formed by a convex portion arranged throughout the first region, and a second region including an uneven surface formed by a plurality of ridges arranged in parallel throughout the second region, the second region being arranged adjacent to the first region. The minimum separation distance between apices of the convex portion in the first region is shorter than the minimum separation distance between apices of two adjacent ridges in the second region.

A pneumatic tire includes a sidewall surface 10 having a profile surface formed in a curved surface shape and a decorative area 11 provided on the sidewall surface 10, in which a plurality of planes 19, 20 with a rhombus shape and a plurality of planes 21, 22 with a shape of part of a rhombus are tightly arranged in the decorative area 11 so that sides and vertices of the rhombuses correspond to one another, two planes 20, 21 and two planes 19, 22 in which perpendicular line directions are different are aligned in a tire radial direction, and vertices to be contact points between the two planes 20, 21 and between the two planes 19, 22 aligning in the tire radial direction are protruding vertices 23, 24 protruding in a normal line direction of the profile surface.
