CURED TREAD AND TIRE

摘要

The invention provides a cured tread and a tire capable of controlling irregular wear of the tread. A base tire which is to be the base for the tire and a cured tread which is to be bonded to the base tire are molded separately, and they are integrated with each other to produce the tire. The tread is provided in its width (axial) direction with a plurality of grooves extending in its length (circumferential) direction. The thickness of the tread in a width cross section gradually decreases from the equator to the equator-side edge of the outermost groove located at an axially outermost position and gradually increases from the outer edge of the outermost groove outward in the axial direction.
