A vehicle tire having a sidewall with at least one sidewall decoration that extends at least over a circumferential portion of the sidewall and is made up of structured surface elements, smooth surface elements and base hatching that adjoins these surface elements and is made up of hatching ribs that extend without branching and intersecting, wherein the structured surface elements reproduce a copy or a shadow at least of partial regions of smooth surface elements, and the structured surface elements absorb light to a greater extent than the base hatching. The structured surface elements are each provided with an area-covering contrast structure with branched rib portions, wherein each branched rib portion has intersection points from which the rib portion respectively extends in at least three directions.

Pneumatic vehicle tire

A method for producing a molding tool () of a vulcanization device for the molding vulcanization of a vehicle tire (), wherein the molding tool () has a negative contrast structure () on a molding surface of the molding tool (), with the following steps: a) providing the molding tool () having the molding surface for the stamping of a surface () of a vehicle tire () in a molding manner in the course of the vulcanization of the tire by means of the vulcanization device, b) creating a first surface structure () of first depressions () by means of a machining process, wherein the first surface structure () extends at least over a surface region () of the molding surface, c) creating a second surface structure () of second depressions () by means of laser engraving, wherein the second structure () extends at least over the surface region () and wherein the first surface structure () and the second surface structure () together form the negative contrast structure () in the surface region ().

Combined production method for a moulding tool for the moulding vulcanization of a vehicle tire and vehicle tire

The invention concerns a pneumatic vehicle tire having a tread and sidewalls, wherein the tread has at least one shoulder-side profile rib with a shoulder portion extending from the lateral edge of the ground contact patch of the tread in the direction of the respective sidewall and having an outer face, and containing rectangular depressions which are formed elongate transversely to the circumferential direction and are each delimited by a base and in the circumferential direction by side faces, wherein the base, viewed in cross-section transversely to the circumferential direction, has an inside base portion running towards the outer face with a maximum extent length, and an outside base portion with a maximum extent length.

Pneumatic vehicle tyre

The invention relates to a pneumatic tire for a vehicle, having formed on its outer surface at least one surface element () with a contrast structure () which imparts a roughness to the surface element (). In the case of a tire of said type, it is the intention to make available a contrast structure with a considerably improved contrast effect. This is achieved in that the contrast structure () is a large-area, nonuniform hill-and-dale contrast structure () having an areal roughness value Saccording to EN ISO 25178 of 50 μm to 150 μm.

Pneumatic tire for a vehicle

Vehicle tyre

A pneumatic vehicle tire () having sidewalls () and having a tread () and having at least one hatching area () on at least one of the sidewalls () and/or on the tread (), wherein the hatching area () has mutually adjacently arranged hatching elements (), wherein each hatching element () has a hatching rib (). The problem addressed is that of influencing the contrast effect in even more targeted fashion, and further increasing the contrast effect. It is furthermore sought to allow improved ventilation capability during the production of the tire by means of a vulcanization mold. This is achieved in that each hatching element () has short transverse elevations (), which cross the hatching rib () in crossing regions (), wherein the short transverse elevations () cross in each case exactly one hatching rib ().

Pneumatic vehicle tire having a hatched surface

A pneumatic vehicle tire () having sidewalls () and a tread () and having at least one marking surface () on at least one of the sidewalls () and/or on the tread (), wherein the marking surface () has two parallel sets (') of elongate elevations (′), wherein the two parallel sets (′) intersect and form a parallelogram grid. The problem addressed is therefore that of influencing the contrast effect in even more targeted fashion, and further increasing the contrast effect. It is also the intention to realize easy producibility of the tire. This is achieved in that the parallelograms of the parallelogram grid have an interior angle () of 35° to 90°, and in that at least one parallelogram, preferably at least half of the parallelograms, particularly preferably all of the parallelograms, has or have an additional elevation () within its or their areal extent.

Pneumatic vehicle tires having a marking surface

Pneumatic vehicle tire having sidewalls and having at least one hatching area () or a hatched area element on at least one sidewall, wherein the hatching area () or the area element has a multiplicity of hatching ribs (″) running next to one another and having two lateral flanks (). The one lateral flank () of the hatching ribs (″) has a surface finish which differs from that on the other lateral flank () of the hatching ribs (″).

An off-road tread profile with radially elevated profile elements, which are separated by circumferential channels, and with transversely running channels which open into circumferential channels, wherein the circumferential channels are formed, along their extent over the circumference of the tire, with a varied axial inclination, wherein, in the channel base of a circumferential channel, elevated stone deflectors are formed so as to be free from contact with the channel walls, which stone deflectors are formed from a cylindrical or frustoconical central body with maximum diameter D, the cylinder or cone axis of which is oriented in the radial direction, and from in each case one web-like body situated in front of the body in the extent direction of the circumferential channel and one web-like body situated behind, wherein the two web-like bodies are each formed so as to extend from the shell surface of the central body so as to be oriented parallel to the extent direction of the circumferential channel and point radially away from the central body and with a maximum width b, where (0.5 D)&#x2265;b&#x2265;1 mm, wherein central bodies are positioned in each case exclusively in circumferential extent regions of opening-in points of at least one transversely running channel into the circumferential channel.

Vehicle tire

A pneumatic vehicle tire having a tread divided by circumferential grooves, which have a profile depth (T), into block rows running in encircling fashion in a circumferential direction and/or profile ribs which are structured in the manner of profile blocks. Block rows are divided by transverse grooves into blocks and, like the profile ribs structured in the manner of profile blocks, are equipped with blind grooves proceeding from the circumferential grooves. Transverse and/or blind grooves are provided which, owing to a connection of blocks adjacent in the circumferential direction and/or of the block-like structures, have a depth smaller than profile depth (T). The connection has at least two connection steps of different heights, the lowest is formed in each case at the region in which the transverse grooves and/or blind grooves open into the circumferential grooves.

The tread profile of a vehicle tire has a circumferential rib. Grooves are formed in the circumferential rib with a width, which increases along its entire extent, wherein the grooves are formed with a vertex point between a first portion and a second portion. The groove direction from the beginning to the vertex point is formed with a greater directional component in the circumferential direction than in the axial direction and between the vertex point and the entry into the circumferential groove is formed with a greater directional component in the axial direction than in the circumferential direction. The groove is formed in the first portion with a depth T, which increases continuously from the beginning over the first portion up to reaching its maximum value Tat the vertex point and is formed with a constant depth Tin the second portion wherein T&#x2265;T.
