<p><P>PROBLEM TO BE SOLVED: To achieve both drainage performance and DRY performance in a tire in which a lug groove extending in a tread direction is formed in a land part adjacent to a peripheral groove extending in a tire peripheral direction and in which an end of the lug groove communicates to the peripheral groove. <P>SOLUTION: The tire 1 includes a land part 50A formed of a peripheral groove 30A extending in a tire circumferential direction and a lug groove 70 extending in a tread width direction. The land part 50A is adjacent to the peripheral groove 30A in the tread width direction. An end 70a of the lug groove 70 on the peripheral groove 30A side communicates to the peripheral groove 30A. The groove width Wr of the lug groove 70 is made narrow in the end 70a of the lug groove 70. A protrusion 100 upheaving toward the outside of the tire radial direction is formed on the groove bottom 75 of the lug groove 70. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
