Title:
TIRE
Document Type and Number:
Japanese Patent JPS5293005
Kind Code:
A
Abstract:
A pneumatic tire for vehicles has a tread band provided with grooves which extend circumferentially about the tire. The grooves are formed by a series of substantially rectilinear sections which are disposed at a predetermined angle with the equatorial plane of the tire and intersect to impart a zig-zag arrangement to the grooves about the tire. The intersections between said groove sections are situated in planes parallel to the equatorial plane of the tire, and each tread surface portion between one of the parallel planes and a pair of adjacent sections of a groove is shaped so the distance at its points from the tire axis gradually decreases from the parallel plane toward the region in which the sections of the pair of adjacent sections intersect.
