<p><P>PROBLEM TO BE SOLVED: To provide a construction vehicle wherein the heat radiating property of a tire center part is improved. <P>SOLUTION: This tire for the construction vehicle has two or more lug grooves 22 formed in a tread shoulder area S on both sides in a tire width direction. Also, the tire has two or more cross-the-width narrow grooves 24 extending nearly in the tire width direction V, terminated within the tread in both ends thereof and arranged in the tire center part C. Further, the tire for the construction vehicle has an on-equator groove 26 extending in a tire circumferential direction on a tire equator surface CL and having depth of the deepest section set within a range of 70 to 110% of the depth of the lug groove 22. Thereby, the high temperature groove bottom part 26B of the on-equator groove 26 is efficiently cooled. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
