Abstract

PURPOSE: To ensure that various kinds of tires with wear indicators can easily be produced according to the conventional forming technique by a method wherein holes are bored in a rubber tread extruded from a tuber, and a wear indication rubber piece consisting of plural colored rubber layers is buried in each of the holes.
CONSTITUTION: Plural holes 3 are bored in the surface of a rubber tread 1 extruded from a tuber, and a wear indication rubber piece consisting of plural colored rubber layers (e.g. one comprising a central colored rubber layer 2 sandwitched by rubber layers 4 of the same color as the tread) is fitted in each of the holes 3 at a level slightly shallower than the deepest position of grooves 5 cut in the tire tread. Then the rubber tread 1 is attached on a carcass by a conventional tire forming method. Thus, the conventional tire producing method plus a little work leads to easy production of various kinds of tires such as airplane tires and radial-ply tires with wear indicators.
