Abstract
A vehicle tire includes a tread portion provided on each side of the tire equator with a plurality of main grooves, displaced relative to one another in the circumferential direction, extending axially outwardly from starting positions near the tire equator beyond a position at 25% of the ground contact width from the tire equator. The main grooves on each side are inclined at an acute angle which becomes greater in the course of the longitudinal extent of the main grooves.
