A pneumatic tire for motor vehicles has a running surface profile designed in the direction of rotation, with two shoulder regions (S , S ) each being a constituent of a row of shoulder blocks, and with a middle region (C) separated from them by circumferential grooves ( ) running in the circumferential direction; this middle region encompasses the width of the circumferential grooves ( ) and covers a minimum width of 60% of the width of the running surface (B), is free from circumferential grooves running in the circumferential direction and is equipped with a number of V-shaped running rills ( ), which open into the circumferential grooves ( ) and whose V-peaks rest at least essentially on the equator line (M&mdash;M). In the two partial regions of the middle region (C) running to the side of the equator line (M&mdash;M) there are a number of slanting grooves ( ) which are oriented in the same direction to the course of the V-shaped rills ( ), crossing at least three V-shaped rills ( ) following each other in the circumferential direction and being at least essentially of a straight design, wherein these slanting grooves ( ) run at an incline at a much smaller angle (&bgr;, &bgr;&prime;) to the equator line (M&mdash;M) than the V-shaped rills ( ) and which are the widest of all grooves or rills of the profile, wherein the slanting grooves ( ) of the one partial region of the middle region (C) are offset in the circumferential direction with respect to those of the other partial region.
