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.

Identification labels and their incorporation in rubber-based articles are described. The labels include RFID components and can be incorporated in tires. The labels can withstand the relatively harsh conditions associated with vulcanization.

A surface of each of the portions of a pneumatic tire includes a ridge pattern region provided with a plurality of ridges continuously extending in one direction and provided at intervals, a non-ridge pattern region including a smooth surface and not provided with the ridges, and a two-dimensional code including a dot pattern formed from two types of gray scale elements distinguishably formed using surface irregularities. The two-dimensional code is engraved entirely overlapping the ridge pattern region or engraved overlapping the ridge pattern region and the non-ridge pattern region.

A pneumatic tire is provided with a carcass layer and a sidewall rubber disposed on an outer side in a tire width direction of the carcass layer. Additionally, the pneumatic tire is provided with a resin coating applied on a predetermined region of a sidewall portion. Additionally, a minimum value of a wall thickness t of a rubber of the sidewall portion in the region applied with the resin coating is in a range of 0.05 mm≤t≤4.0 mm. Additionally, a thickness of the resin coating is in a range of 20 μm or more and 300 μm or less.

A tire comprises an inner surface defining and facing an inner hollow space, an outer surface pointing away from the inner hollow space. A method of processing the tire comprises identifying the position of a first feature on the outer surface and cleaning a surface portion of the inner surface of the tire, wherein the surface portion has a first predetermined position relative to the position of the first feature on the outer surface. A separate element is attached with its attachment surface to the surface portion, wherein a ratio of a size of the surface portion over a corresponding size of the attachment surface is smaller than 10.

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 method of laminating a vulcanized tire includes providing a vulcanized tire having a circumferential tread and a pair of sidewalls constructed of a base rubber. The method further includes cleaning the circumferential tread, providing a laminate, and forming a plurality of holes in the laminate. The method also includes applying the laminate to at least a portion of one of the circumferential tread and a sidewall of the vulcanized tire. The method further includes applying pressure to the laminate, thereby evacuating air between the laminate and the circumferential tread of the vulcanized tire and curing the laminate.
