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.

A tire vulcanization mold includes a molding surface for molding a tire during vulcanization molding. The molding surface can include a first region in which a plurality of recesses for forming a plurality of projections on a surface of the tire can be provided. In the first region, at least two of the recesses can be arranged per mm.sup.2. Each of the recesses can include a side wall surface, a bottom surface, and a virtual recess central axis extending in a depth direction of the recess. In a cross-sectional view of the recess including the recess central axis, the bottom surface can include a bottom projection projecting outward in the depth direction, and the side wall surface can include an arc-shaped surface smoothly connected to the bottom surface.

The disclosure relates to a selective laser sintering method of manufacturing a tread molding element, said tread molding element including at least a fine lamella adapted to mold a shallow ripe in a tire tread, the fine lamella having a length (L2). The fine lamella is sintered in a plurality of portions (p2) at different layers (N), in each layer (N) the laser beam sinters the portion (p2) of the fine lamella in only one passage in the length (L2) of the fine lamella without round-trip passage of the laser beam, the direction (D1) of this passage being the same at the different layers (N) for building the different portions (p2) of the fine lamella. The thickness (w) of the fine lamella is smaller than 0.2 mm, and the height (h) of the fine lamella is smaller than or equal to 2 mm.

A method is for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires, the molding area of which molds a segment of the tread profile of a tire to be vulcanized, including the steps: creating a rigid model segment having a casing-like tread surface; milling the profile positive of the tread into the casing-like tread surface of the model segment to obtain the master model; creating a flexible impression from the master model; creating a rigid plaster cast from the impression to form a casting core segment; casting all of the annular, placed-together casting core segments with an aluminium-magnesium alloy to obtain a vulcanizing mold, subsequently divided into profile segments. A plasma coating is applied to the tread of the model segment, into which the profile positive of the tread is subsequently milled to obtain the master model. Plasma coating gives the master model a defined roughness.

A mold for vulcanizing and molding a tire is provided herein. The tire includes a tread delimited by two sidewalls, the mold including a ring for molding the tread of the tire and two shells for molding the sidewalls. The mold includes an annular groove extending in a recessed manner in one of the shells and an insert housed in the groove, this insert having tire marking elements and being formed from a plurality of insert parts that are positioned one after another in the annular groove.

A tire vulcanization mold in which a surface roughness in the groove molding portion of the tread molding surface is made smaller than a surface roughness in the land portion molding portion, in which a surface roughness in the groove molding portion is minimized to 0.12 μm or less in a range including at least a main groove molding portion, and in which a surface roughness in the land portion molding portion is made to be 3.2 μm or more, is used to manufacture a tire, and when cleaning the tread molding surface, the tread molding surface is irradiated with a laser beam to remove contaminant adhered to the tread molding surface.
