Problems solved by technology

[0004] Light or small tire noise / Road noise, however in practice the pitch sequence and pitch length in a tread are not arbitrarily combined with each other, as the result could be, for example, uneven wear or poor hydroplaning properties

Embodiment Construction

[0016] exist figure 1 In , one tread of a pneumatic tire for vehicles shows one rib 1 and another rib 2 in a radial configuration for cars, trucks and similar vehicles, the other rib being passed through a wide , the circumferential groove 3 surrounding in the circumferential direction is separated from the tread rib 1 . Instead of the tread ribs, it is also possible to provide circumferential rows of tread blocks in the circumferential direction. In the illustrated embodiment, a further circumferential sipe 3' running around in the circumferential direction extends along the rib 2 on the inside of the tread, which is adjoined by a not shown sipe. Both the tread rib 1 and the tread rib 2 are of a block structure, the tread rib 1 is constructed by the transverse groove 4 , and the tread rib 2 is constructed by the transverse groove 5 . exist figure 1 In the embodiment schematically shown in , the transverse grooves 4 extend in such a way that they are at a distance inside th...

Abstract

A vehicle pneumatic tire with a tread has at least two tread regions surrounded annularly in the circumferential direction with defined width, such as tread ribs (1, 2) which are composed of circumferentially successive tread units implemented by a similar geometry, that is the so-called pitched (P1 to P5, P1' to P5'). The pitches are set with at least three different circumferential lengths (L1 to L5, L1' to L5'), the pitches (P1 to P5, P1' to P5') are arranged in the respective tread regions on the tire circumference in a respective noise optimized sequence, and total number of the pitches (P1 to P5, P1' to P5') in at least one tread region surrounded annularly in the circumferential direction differs from the total number of the pitches (P1 to P5, P1' to P5') in at least the other tread region surrounded annularly in the circumferential direction. The total number of the pitches (P1 to P5) in the tread regions having the largest total number of pitches is at most 3% greater than the total number of the pitches (P1 'to P5') in the tread regions having the smallest total number of pitches.

Description

technical field [0001] The invention relates to a pneumatic vehicle tire with a tread having at least two tread regions, such as tread ribs, of defined width that run around in the circumferential direction, the tread ribs being respectively implemented by Assembled from geometrically homogeneous tread units arranged one above the other on the circumference, so-called pitches (Pitches), these pitches are arranged at least three different circumferences, wherein the pitches are on the tire circumference The arrangement in each tread area is based on an own noise-optimized The pitches take place sequentially, wherein the total number of pitches in at least one annularly surrounding tread region differs from the total number of pitches in at least one further annularly surrounding tread region. Background technique [0002] In the profile configuration of the tread of a pneumatic tire for vehicles, it is common to have similar tread segments arranged one above the other on th...
