Abstract A profiled pneumatic vehicle tire is provided that comprises a tread surface that includes grooves that, when viewed in plan, extend at an angle relative to the circumferential direction of the tire. The grooves have sides that extend at an angle relative to a radial line. The distance between successive grooves in the circumferential direction is modulated in conformity with a pitch sequence that varies the excitation frequency, so that positive profiling portions having varying dimensions in the circumferential direction are provided between the grooves. Not only the dimension of the grooves in the circumferential direction are also modulated in conformity with the pitch sequence, but the tangent of the angle of the sides of the grooves are also modulated in conformity with the pitch sequence.

A profiled pneumatic vehicle tire comprising a tread surface that includes grooves that, when viewed in plan, extend at an angle relative to a circumferential direction of said tire, said grooves having sides that extend at an angel relative to a radial line, said tread surface being divided into a number of pitches, the dimension of at least two successive pitches in said circumferential direction being different, the width of said grooves in said circumferential direction differs, whereby for each pitch, the proportion of said dimension thereof in said circumferential direction to said width of the pertaining groove is the same, and the tangent of said angle of said sides of said grooves differs, whereby for each pitch, the proportion of said dimension thereof in said circumferential direction to the tangent of the angle of the pertaining groove is the same.
