A corresponding device for producing the rubber components (1) is also specified.

Abstract: A pneumatic vehicle tire (1) having sidewalls (2) and a tread (3) and having at least one marking surface (4) on at least one of the sidewalls (2) and/or on the tread (3), wherein the marking surface (4) has two parallel sets (5, 5?) of elongate elevations (6, 6?), wherein the two parallel sets (5, 5?) 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 (7) 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 (8) within its or their areal extent.

Abstract: A two-wheeler pneumatic tire, in which damage protection and puncture protection are improved while providing good rolling resistance and good tightness; the two-wheeler pneumatic tire in the bead regions has a protective layer which is disposed axially outside the carcass and which has strength members embedded in rubber material; wherein the tire carcass is formed from a first carcass ply and a second carcass ply disposed radially within in a vertex, and wherein the second carcass ply ends with a second carcass ply turn-up in a second carcass ply end in the bead region; the purpose of damage protection and puncture protection is achieved in that the first carcass ply is guided from the respective bead region in a first carcass ply turn-up over the respective tire sidewall to below the tread and at the latter ends in each case in a first carcass ply end; and that in each of the two axial halves the protective layer is guided from the bead region over the respective tire sidewall to below the tread.

Abstract: Pneumatic vehicle tire having sidewalls and having at least one hatching area (1) or a hatched area element on at least one sidewall, wherein the hatching area (1) or the area element has a multiplicity of hatching ribs (2, 2?, 2?) running next to one another and having two lateral flanks (3a, 3?a, 3?a, 3b, 3?b, 3?b). The one lateral flank (3a, 3?a, 3?a) of the hatching ribs (2, 2?, 2?) has a surface finish which differs from that on the other lateral flank (3b, 3?b, 3?b) of the hatching ribs (2, 2?, 2?).

Abstract: A pneumatic vehicle tyre of radial type of construction, having a tread (1), having a carcass inlay (3), having electrically nonconductive sidewalls (7) and having at least one electrically conductive component (8) or element in a bead region, which component or element, in the case of a tyre mounted on a wheel rim, comes into contact with said wheel rim, wherein either the tread (1) is electrically conductive or, in the tread region, at least one electrically conductive component (10) is provided which is overlapped on the outside by the sidewalls (7) and which is connected in electrically conductive fashion to the tread outer surface, and wherein filaments provided with an electrically conductive coating are incorporated at least in a sidewall region, the coating of which filaments forms electrically conductive passages between the tread (1) or the component (10) and the at least one electrically conductive component (8) or element in the bead region.

Abstract: A pneumatic vehicle tire in radial design that is a summer tire or all-season tire, with a profiled tread comprising rows of profile blocks and/or profile ribs running around the tire in circumferential direction, wherein the total number of sipes within each row of profile blocks and/or profile ribs is not more than 150, wherein the tread is in the form of a single layer or multiple layers with a radially outermost tread layer that extends at least over the width of the ground contact area, and wherein the profile depth of the tread is up to 6.5 mm.

The channels have depressions delimited by a curved surface.

Abstract: A two-wheeled vehicle pneumatic tire having a tread, a tire carcass, tire sidewalls, and two bead regions with a bead protective strip. The tire carcass is formed from a first carcass inlay and a second carcass inlay. The second carcass inlay is arranged radially inwardly of the first carcass inlay, and extends from a crown region (17) of the two-wheeled vehicle pneumatic tire and terminates at a second carcass inlay end under the bead protective strip. The two-wheeled vehicle pneumatic tire provides improved puncture protection whilst maintaining good rolling resistance. This is achieved in that the first carcass inlay is guided with a first carcass inlay turn-up over the particular tire sidewall as far as under the tread to a first carcass inlay end, and terminates there at the first carcass inlay end.
