ABSTRACT:
A pneumatic vehicle tire for trucks, especially for the drive axles thereof. In the region of the edges of the tread, the tire has circumferential rows of blocks separated by grooves that open freely to the sides. Provided to both sides of the laterally outwardly disposed rows of blocks is a practically cylindrical surface. In order to increase the capacity of the shoulder regions of the tire to withstand dynamic stresses, and also in order to increase the support surface of the tire upon soft ground, the base of the aforementioned grooves merges in a stepless manner with the lateral cylindrical surfaces. Advantageously, the laterally outwardly disposed edges of those blocks that form the edges of the tread merge with steep side surfaces that are disposed perpendicular to the cylindrical surfaces.
