<p><P>PROBLEM TO BE SOLVED: To provide a tire enabling visual detection of an amount of wear of a lug without using any tool. <P>SOLUTION: At least either one of tire rotation direction front and rear side faces of the lug 14 is provided with a plurality of protrusions 16. For the protrusions 16, the protrusions of which cross section is a substantial semicircular shape is extended in a tread width direction of the tire connecting a center direction of the tire with a shoulder part. Spaces between the protrusions in a tire radial direction become narrower at a center side of the tire and become wider at a shoulder side. The plurality of protrusions 16 respectively form curves toward a rotation center of the tire from the center side to the shoulder side of the tire. The curves respectively formed by the protrusions 16 indicate lines on which a surface of the lug 14 is expected to position as wear of the lug 14 progresses. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
