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 decal marker used with a marking station interchangeably carries a decal tape and a marking tape and transfers a decal from the decal tape to a surface to be marked. A marking assembly frame and at least one marker carried by the marking assembly frame which carries the decal tape or the marking tape are included. A tape sensor assembly is carried by the at least one marker and detects an edge of the decal so that the at least one marker properly positions the decal for transfer to the surface.

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 comprises a toroidal carcass, which has a central cavity and at least one body ply, which is partially folded onto itself and, hence, laterally has two turn-ups, each having an edge of the body ply resting against an intermediate portion of the body ply. Two annular beads are each surrounded by the body ply and having a bead core and a bead filler. An identification label is fixed in a removable manner, for example by gluing, and arranged in the area of an annular bead and supports a temporary RFID device, which can be read from a distance.

The Lummi Rex, is an advanced car tire that displays contrasting colors within the tire by the aid of the shining chromes found on the rims and it is to yield caution to other drivers and pedestrians. The sole purpose of the Lummi Rex is to reduce and eliminate road accidents due to poor driving, drunk driving, irresponsible drivers, reckless drivers, car malfunctions, broken taillights, and miscommunication between drivers, pedestrians, and everything in its surroundings. The mission of the Lummi Rex is, but not limited to ease the communication process between drivers and pedestrians in a novel manner. Pedestrians will know that when this advanced car tire is illuminating in color Blue it means the car ignition is on, color Red means the car is in motion and finally, when the entire tire is glowing in color Green simply means that the brakes have been applied.

A rubber article, such as a tire, bearing a digital code pattern is provided. The rubber article includes a quiet zone that surrounds the digital code pattern. The quiet zone is free of surface features in order to provide enhanced acquisition of the digital code pattern. A marking symbol is formed on the rubber article adjacent the quiet zone to provide identification of the quiet zone. A frame is optionally formed on the rubber article adjacent the quiet zone and the marking symbol to delineate the quiet zone.

A tire has at least one band of cooling fins located on a sidewall portion of the tire. The band of cooling fins has at least one protruding cooling fin and at least one recess located adjacent to the cooling fin. At least a portion of the recess is recessed axially inwards relative to the cooling fin. The cooling fin has a height equal to or greater than an airflow boundary layer thickness at a predetermined location and angular velocity of the tire.

A tire includes plural protrusion portions protrudedly disposed on an outer surface of the tire and configured by ridges having plural straight line portions extending in a direction intersecting each other. A height dimension of the protrusion portion is set to be from 0.2 mm to 0.5 mm, and a pitch of the ridges which configure the protrusion portions adjacent to each other when being viewed in a plan view is set to be from 0.15 mm to 0.40 mm.
