Embodiment Construction

[0048] Figure 1 to Figure 5 Shown is a tread pattern of a vehicle pneumatic tire of a commercial vehicle tire, such a tread pattern with adjacent to each other in the axial direction A of the vehicle pneumatic tire, correspondingly in the entire circumferential direction of the vehicle pneumatic tire Circumferential ribs 1 , 2 , 3 and 4 extending upward and oriented in the circumferential direction U. The circumferential ribs 1 and 2 pass through a circumferential groove 5 , the circumferential ribs 2 and 3 pass through a circumferential groove 6 , and the circumferential ribs 3 and 4 pass through a circumferential groove 7 correspondingly in the known manner in the axial direction A spaced apart from each other. The circumferential grooves 5 , 6 and 7 extend over the entire circumference of the vehicle pneumatic tire and are oriented in the circumferential direction U. as in figure 1 As can be seen in , the circumferential ribs 1 and 4 are correspondingly formed as shoul...

Abstract

The invention relates to a tread profile having radially raised profile elements (1, 2, 3, 4) separated from each other by grooves (5, 6, 7), wherein the grooves (5, 6, 7) are bounded on the inside in the radial direction R by the groove floor thereof (8) and on both sides of the groove floor (8) by one groove wall (9, 10) each extending in the radial direction from the groove floor (8) outward to the generated surface forming the ground contact surface, wherein at least one groove (5) extends over the circumference of the vehicle tire, wherein raised areas (11) of the groove wall (9, 10) each extending radially outward from the groove floor (8) and inward into the groove (5) in the direction perpendicular to the groove wall (9,10) are formed at least in one groove wall (9, 10) and distributed around the circumference at a distance from each other, wherein at least one web-shaped raised area (14) of the groove floor (8) is implemented in the groove floor (8), each starting from a raised area (11) of the one groove wall (10), extending transverse to the direction of extension of the groove floor (8) out to the other groove wall (9), and connecting the other groove wall (9)in the radially inner extension area of the groove (5) to the raised area (11) implemented in the one groove wall (10).

Description

technical field [0001] The present invention relates to a tread strip of a vehicle tire, in particular a pneumatic tire for vehicles, with a plurality of radially raised profiled elements spaced from each other by a plurality of grooves, wherein the grooves are radially bounded upwardly and inwardly by its groove base and on both sides by a groove wall extending outwardly from the groove base in a radial direction R up to the cover forming the ground contacting surface So far, at least one of the grooves is configured to extend over the entire circumference of the vehicle tire. The plurality of ridges of the groove wall protruding into the groove in the direction of , are formed in at least one groove wall dispersed on the circumference and spaced apart from one another. Background technique [0002] Such vehicle pneumatic tires are well known. It is known that the circumferential grooves of pneumatic vehicle tires for commercial vehicles are formed with pyramid-shaped sid...
