A tire having a high contrast design pattern is described, wherein one design has a first set of spaced apart wavy lines oriented in a first direction, and a second set of spaced apart wavy lines oriented in a first direction, wherein the first set of wavy lines is out of phase with the second set of wavy lines. A second high contrast design pattern is described, and is formed of a plurality of circles, wherein the plurality of circles do not overlap with each other and are tangent to each other.

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 mould for vulcanising tyres for vehicle wheels, comprising—at least one sidewall plate (3) on which a moulding surface (4) is defined,—a removable insert (10) arranged to be received in a seat (5) which is made in said sidewall plate and open on said moulding surface, said insert comprising a main body (11; 111) on which a base surface (12) is defined which is intended for contacting a portion of a sidewall (52) of the green tyre, and—a retaining member (20) for retaining said insert (10) inside said seat. The retaining member comprises at least one locking element which is mounted on one out of said insert and said sidewall plate and can be moved in an operating direction (Y) between a locking position, in which said insert is retained inside said seat, and a release position, in which said insert is free to leave said seat.

The present invention relates to an insert (10) for a mould (1) for vulcanising tyres for vehicle wheels, the insert being arranged to be received in a seat (5) formed on a moulding surface (4) of the mould (1) and comprising a base surface (12) from which a plurality of projections (20) extends. Each projection comprises a lateral surface (21) extending away from said base surface (12), which lateral surface defines a tapered profile of said projection (20) away from said base surface (12), is inclined at an angle of between 10° and 25° with respect to a direction (X) perpendicular to said base surface (12), and has a roughness of between 4 and 11 μm. The invention is also related to a process for producing said insert and to a process for producing a tyre for vehicle wheels.

A Smart Patch comprising a label layer, an adhesive layer, a release liner layer and a RFID inlay, wherein the release liner comprises a separable inner release liner portion and a separable outer release liner portion; and the RFID inlay is adhered to a back surface of the inner release liner portion. The Smart Patches for uses including mounting to tires and other rubber materials. Methods of manufacturing including subjecting a release liner of the label to a die cut slightly larger than the size of an intended RFID inlay to form the separable inner release liner portion and outer release liner portion and applying a RFID inlay to a back surface of a release liner within the die cut inner release liner portion.

The present disclosure relates to a tyre comprising a carcass structure, a tread band, a pair of sidewalls and at least one colored decorative element having a thickness equal to or greater than 200 μm applied by co-vulcanization on at least one side of the pair of sidewalls, wherein the pair of sidewalls comprises an elastomeric composition comprising (i) at least one diene elastomeric polymer, and (ii) an ozone protection system, and the at least one colored decorative element is made with a cross-linkable elastomeric composition comprising (i) 100 phr of elastomeric polymer comprising 30 phr to 70 phr of natural and/or synthetic isoprene rubber, and 30 phr to 70 phr of a rubber chosen from butyl rubber, halobutyl rubber, butadiene rubber, styrene-butadiene rubber, and mixtures thereof, and (ii) 5 phr to 120 phr of at least one reinforcement filler.

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.

Provided are a tire with new sidewall pattern and a tire mold, which belongs to the technical field of tire, the tire includes a tire body, a sidewall of the tire body has a labeling region, in which multiple pattern units are provided; the pattern units are provided to protrude from the tire body, the pattern unit includes a curved portion having a curved segment and extension ends provided at both ends of the curved segment. The tire mold is used for manufacturing the tire. The tire has better visual performance and mechanical performance.

Provided is a tire provided with a mark capable of reducing the air resistance during tire rotation while maintaining good visibility. A tire is provided with a mark on a tire side portion. The mark includes a first mark located on an outer side in a tire radial direction, and a second mark located inward of the first mark in the tire radial direction. Each of the first mark and the second mark includes a recess that is recessed from a side profile surface of the tire side portion. A depth of the recess of the first mark from the side profile surface is smaller than a depth of the recess of the second mark from the side profile surface.

Provided is a tire vulcanization mold which includes a sector mold configured to mold a tread portion; and a pair of upper and lower side plates positioned on an inner diameter side of the sector mold and configured to mold side wall portions, the sector mold and the pair of upper and lower side plates being configured to engage with each other by fitting engagement by way of fitting portions which opposedly face each other in a radial direction. At least either one of the sector mold and the side plate has: a recessed portion extending from each fitting surface in a tire radial direction and indented outward in a tire width direction; and a saw cut groove having a groove shape extending in a tire radial direction along at least one of an edge portion and a corner portion of the recessed portion and communicating with the fitting surface.
