My pneumatic tire includes a decoration band formed on the outer surface of a sidewall portion, extending in the tire circumferential direction and including a plurality of recesses and land portions defined between the recesses. A plurality of ridges are provided in each recess. At least a portion of the ridges each have a bending point.

A pneumatic tire with a pair of sidewall portions, which comprises at least one of said sidewall portions with a radially outer region being radially outside than a tire maximum width position of its outer surface, the radially outer region being provided with a serration pattern, the serration pattern comprising a first serration group and a second serration group, the first serration group comprising a plurality of concentrically arranged first arc-shaped ridges at regular intervals around a first center point O1, the second serration group comprising a plurality of concentrically arranged second arc-shaped ridges at regular intervals around a second center point O2 that is located radially outside than the first center point O1 of the first serration group, and the first serration group and second serration group arranged in a circumferential direction of the tire so as to overlap partially.

This tire marking apparatus is a tire marking apparatus for performing marking in a tire. The tire marking apparatus includes a disk part having a central axis that is adjusted substantially perpendicularly to a printing surface of the tire; a plurality of printing parts that are provided in the disk part so as to be capable of moving forward and backward with respect to the printing surface and are arranged around the central axis; and a printing driving unit that moves at least one printing part arranged at a printing position that faces the printing surface of the tire forward.

One of sidewalls of a pneumatic tire is engraved with a two-dimensional code on a side rubber surface. The two-dimensional code is formed of a dot pattern made up of two types of gray scale elements distinguishable from each other by irregularities on the surface. The side rubber has a thickness at an engraving position of the two-dimensional code from 110 to 150% the average thickness of the entire side rubber.

A non-pneumatic or pneumatic tire includes an area for tire indicia or markings. The tire includes a hub region and a tread layer. The tread layer of the tire has a shoulder with a cut out extending either partially or entirely around the shoulder of the tire tread layer. The angle of the notched or beveled portion is 45-135° with respect to an axial direction along the tread layer shoulder, and at least one indicia disposed on the at least one flat surface. The placement of the markings may be radially along the surface of the cut out portion or axially along the surface of the cut out portion. The markings may be recessed, stamped, molded, painted or applied with ink to the cut out portion. Alternatively, the indicia or marking may be applied to a decal and applied to the cut out portion.

A pneumatic tire includes a carcass layer that has a toroidal shape and extends between a pair of bead portions, a sidewall portion, one of the pair of bead portions being provided at an inner end of the sidewall portion in a tire radial direction TR, and a mark formed in an outer surface of the sidewall portion. The mark includes a protruded portion provided in the outer surface of the sidewall portion and recessed inward in a tire width direction, and a mark body defined by the protruded portion. The surface of the mark body coincides with a reference surface corresponding to the outer surface of the sidewall portion.

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.

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.

Display assemblies as disclosed herein are configured for attachment with a vulcanized rubber article and are provided in the form of different material layers. Display assemblies generally comprise one or more display layers of elastomeric material configured to provide a desired display indicia, an intermediate layer formed from an elastomeric material different from that of the one or more display layers, and an adhesive layer wherein the intermediate layer is interposed between the adhesive layer and the one or more display layers. The one more display layers may be configured to act together or separately to provide a desired display indicia to provide a desired visual display or feature on the surface of the vulcanized rubber article, which may be a sidewall surface of a tire.

A tire side surface of a pneumatic tire includes a two-dimensional code in which a dot pattern is formed by two types of gray scale elements formed identifiable from each other by recesses and protrusions of the tire side surface, or a predetermined two-dimensional code arrangement region. The tire side surface further includes at least two marks formed in a protruded shape or a recessed shape, and the two marks are disposed on an identical position in a first direction of a tire radial direction and a tire circumferential direction and disposed separated from each other at different positions in a second direction of the tire radial direction and the tire circumferential direction to sandwich an outer edge of the two-dimensional code or the predetermined two-dimensional code arrangement region from the opposite sides in at least one of the tire radial direction or the tire circumferential direction.
