Problems solved by technology

This reduces the engagement of the spikes and thus the mechanical action of the spikes into the ice, and reduces the cutting effect of the spikes during braking and traction
Also reduces rubber-ice friction in the area of ​​the spikes

Embodiment Construction

[0057] Figures 1 to 3 Shown is a profiled block element 1 of the tread stripe of a vehicle pneumatic tire for a passenger car, which profiled block element is formed in a known manner in the circumferential direction U of a vehicle pneumatic tire correspondingly by a profiled block element A transverse groove 2 arranged before 1 and a transverse groove 2 arranged after the profiled block element 1 are delimited and are respectively bounded on both axial sides in the axial direction A of the pneumatic tire for vehicles by a circumferential groove The groove 3 is bounded by a circumferential groove 4. The profiled block element 1 is delimited in the radial direction R of the pneumatic vehicle tire by a surface 8 forming the cover of the pneumatic vehicle tire and forming the ground-contacting surface.

[0058] In the profiled block element 1, a nail 5 having a body 6 having a cylindrical cover and a foot 7 is fastened in a nail hole. The spike body 6 extends radially outwards...

Abstract

The invention relates to a tread profile of a pneumatic vehicle tire having a plurality of radially raised profile elements (1) spaced apart from one another by means of scores (2, 3, 4) or grooves, each being delimited in the radial direction R to the outside by an outer surface (8) forming the ground contact surface, wherein at least one spike (5) is formed in at least one profile element (1) which is anchored by the spike body (6) thereof in the rubber material of the profile element (1) and designed having a spike point which extends out of the spike body (6) in the radial direction R of the tire and ends in a radial position outside that of the outer surface (8) of the profile element delimiting the profile element (1) radially to the outside and forming the ground contact surface, wherein there is a recess (9) formed in the outer surface (8) delimiting the profile element (1); radially to the outside and forming the ground contact surface for expelling ice which surrounds the spike (5) in a substantially ring-shaped manner.

Description

technical field [0001] The present invention relates to a tread strip of a pneumatic tire for vehicles having a plurality of radially raised profile elements spaced apart from one another by a plurality of sipe or grooves, each of which is formed outwardly in the radial direction R by A cover delimitation forming a ground-contacting surface, wherein at least one nail is formed in at least one profile element, the nail is anchored with its nail body in the rubber material of the profile element and is formed with a nail point, the nail point resting on the tire The nail body protrudes in a radial direction R of 2 and terminates at a radial position outside the profile element cover constituting the ground-contacting surface delimiting the profile element radially outwards. Background technique [0002] Such pneumatic tires for vehicles are well known. In conventional spiked vehicle pneumatic tires, the spikes are inserted into the profiled blocks at the locations provided fo...
