Abstract
A tread configuration for motor vehicle tires, especially spare tires, with several peripheral rows of essentially V-shaped blocks, with the points of successive blocks, as seen in the peripheral direction of the tire, alternately pointing in opposite directions transverse to the circumferential or peripheral direction of the tire. Three rows of blocks are provided, and are separated from each other by linearly extending peripheral grooves. The width of the two outer rows correspond essentially to the axial dimension of a block; in the middle row, the successive blocks are laterally displaced or offset with respect to each other in such a way that the width of this middle row is approximately 1.3 to 1.8 times the axial dimension of a block individually. The depth of the slanted or inclined grooves located between successive blocks of the middle row is essentially smaller than the depth of the remaining inclined grooves located between the blocks and of the peripheral grooves located between the rows of blocks. The axial distance of the blocks located in the outer rows is practically equal and that also the axial distance of all blocks located in a center or middle region is practically equal and the axial distance of the blocks in the center or middle region is smaller by approximately 20% to 40% than the axial distance of the blocks located in the outer rows. The depth of the inclined grooves of the center or middle row amounts to approximately 1/4 to 1/3 of the depth of the remaining grooves. The width of the inclined grooves in the center region amounts to approximately 1/2 to 3/4 of the width of the peripheral grooves on either side of the center or middle region.
