<P>PROBLEM TO BE SOLVED: To provide a tire for agricultural use capable of reducing vibration during the traveling by uniforming the ground contact pressure of a lug 4. <P>SOLUTION: Each lug 4 comprises a shoulder part 6 formed close to a side wall part 5 of a tire body 2, and a center side ground contact part 7 formed on an equatorial plane EP side from the shoulder part 6 in the width direction X. An edge 16 closer to the equatorial plane of the center side ground contact part 7 is formed in a substantially arc-shaped or substantially straight manner. The length L1 in the circumferential direction Y of the substantially arc-shaped or the substantially straight edge 16 is set to be larger than the length L2 in the circumferential direction Y of the shoulder part 6. The length L1 in the circumferential direction Y of the substantially arc-shaped or substantially straight edge 16 is 35-60% of the pitch P of the center side ground contact part 7 of the first lug 4a and the center side ground contact part 7 of the second lug 4b. <P>COPYRIGHT: (C)2008,JPO&INPIT |
