Embodiment Construction

[0050] figure 1 An asymmetrical tread rubber pattern is shown for a radial type passenger car tire, which pattern is particularly suitable for year-round use. exist figure 1 Among them, A-A represents the central equatorial plane or equator line, which divides the tread rubber into two halves, and B represents the tread when a tire with this tread rubber is mounted on the rim and is in normal operating condition The contact width of the rubber, O denotes the outer shoulder, which is located on the outside when the tire is mounted on the vehicle, and I denotes the inner shoulder facing the center of the vehicle.

[0051] like figure 1 As shown, the pattern of the tread rubber (from the outer shoulder O to the inner shoulder I) has a row of tread blocks 1, a circumferential rib 2, a wide tread band 3, the wide tread The band occupies approximately 40% of the contact width B, extends around in the circumferential direction and is divided into a plurality of tread blocks 16 . ...

Abstract

The present invention relates to a pneumatic vehicle tire comprising a tread that is divided into tread elements, such as tread blocks (1a, 2a) or circumferential ribs (2), by circumferential grooves (5, 6, 7) and lateral grooves (8, 9), wherein a groove edge (19) of the circumferential groove (6) located at a greater distance from the outer shoulder (O) extends at a first angle of inclination (beta1) to the radial direction, and the groove edge (18) opposite said groove edge comprises two edge sections (18a, 18b) that extend at an angle of inclination (beta2) and a third angle of inclination (beta3) to the radial direction, wherein the radially inner edge section (18b) is provided with the elevations (20) that form a ribbed structure.

Description

technical field [0001] The present invention relates to a pneumatic vehicle tire with tread rubber divided into tread elements, such as tread blocks or circumferential ribs, by a plurality of circumferential grooves and a plurality of transverse grooves, And the pneumatic vehicle tire has an outer shoulder on the outside with respect to the vehicle and an inner shoulder facing the longitudinal axis of the vehicle, the tread rubber has at least one circumferential groove, the circumferential The groove has a groove bottom extending on the circumference of the tread rubber and with groove sides extending radially outward on both sides of the groove bottom and delimiting the circumferential groove, the grooves One of the groove sides is structured in a ribbed manner by ridges oriented in the transverse direction of the tread rubber. Background technique [0002] Pneumatic vehicle tires of this type are known, for example, from US-A-7,986,372. This tread rubber has a plurality...
