Abstract
A tread structure for pneumatic vehicle tires, according to which the tread is provided with a centrally arranged zigzag groove extending in the circumferential direction of the tire. The tread also has elevations or raised sections on both sides of the circumferential groove. The elevations follow one another in the circumferential direction of the tire, and are separated from one another by other grooves, including grooves which start from the zigzag central circumferential groove and extend straight towards both tire shoulders. Of these straight grooves, those which follow one another in the circumferential direction of the tire are slanted in opposite directions with regard to the circumferential or transverse direction of the tire.
