ABSTRACT:
A vehicle tire of a radial carcass construction with a low cross-sectional profile having a tread portion that is reinforced by a belt layer is provided. The tread portion comprises two circumferential tread element bands in a center portion of the tire tread and a respective tread element row on the shoulder portion. The tread element bands are separated from one another and from the tread element rows in an axial direction of the vehicle tire by respective wide and deep circumferential grooves that have straight edges. The tread element bands have notches that are distributed in a circumferential direction of the vehicle tire and are oriented at a slant relative to a center plane of the vehicle tire. The notches begin at the circumferential grooves and end within the tread element bands. The tread element rows comprise transverse tread elements that are separated from one another by continuous transverse grooves and are arranged transverse relative to the tread element bands.
The tread element bands are provided with narrow grooves that are distributed in the circumferential direction, spaced relative to one another by twice a circumferential length of a tread element repeating unit, defined by the shoulder tread elements and are slanted at a first angle relative to the center plane. The narrow grooves are essentially as deep and 1/4 to 1/3 as wide as the circumferential grooves. The transverse grooves each have a bent portion in the vicinity of the circumferential grooves, whereby the bent portion is oriented at a second angle relative to the center plane, whereby the second angle is greater than the first angle of the narrow grooves.
