Abstract: A heavy load pneumatic radial tire having a tire tread sectioned into a plurality of circumferentially continuous ribs by a plurality of circumferentially extending wide main grooves. One of the ribs disposed at the outermost side when the tire is mounted on a vehicle is provided with a narrow groove circumferentially continuously formed in a proportion of 10% to 40% with respect to a width of the outermost rib from an adjacent tread end. The narrow groove separates the outermost rib into two portions. One of the ribs disposed at the innermost side when the tire is mounted on a vehicle is provided with a discontinuous narrow groove circumferentially disposed in a proportion of 10% to 50% with respect to a width of the innermost rib from an adjacent tread end. This discontinuous narrow groove is composed of circumferentially extending groove portions separated from each other by discontinuous portions each having a circumferential length not shorter than 20% but not longer than 50% of a circumferential length of each of the circumferentially extending groove portions.

Abstract: A pneumatic tire having a tread portion comprises a mid-circumferential zig-zag rib and a plurality of blocks located in the edge portions of the tread between adjacent peaks of the zig-zag rib. The zig-zag rib has amplitude of between 60-70% of the tread width and has sied faces thereon that have an exposed length of at least 40% of the tread width. By varying the width of the grooves, between the blocks and the rib, on one rotational directional side of the rib from the width of the grooves on the other rotational directional side of the rib, it is possible for the tire to have different traction grips for each rotational direction.

Abstract: A pneumatic vehicle tire which has fine slits in the tread. These slits are inclined relative to the circumferential direction of the tire. In order to increase the frictional connection to the roadway, to make the wear of the tread more uniform, and in addition to be able to use mechanically stiff plates for the associated vulcanization molds, the fine slits are twisted about an at least approximately radially extending twist axis. The fine slits preferably extend continuously from their roots into the tread surface region proper.

Abstract: In order to prevent the edges of the crown reinforcement of radial carcass tires whose tread contains oblong elements in relief or blocks (tires for earth-moving vehicles and for drive wheels of agricultural tractors) from deforming during the vulcanization of these tires in the vulcanization mold, at least some of these oblong blocks are provided with a furrow whose depth is between 1/2 and 6/5 of the radial height of the oblong block in question and whose length is not greater than 1/3 of the length of the oblong block. The element in relief which, within the mold, serves to mold the furrow within the oblong block of the tread prevents the folding and/or deformation of the crown reinforcement of the tire.
