PROBLEM TO BE SOLVED: To provide a tire for a construction vehicle in which abrasion resistance and heat radiation performance can be improved.SOLUTION: A tire for a construction vehicle includes a first space part 3 extending toward the tire inside on a surface of a tread part 11. A distance A1 in the width direction of the installing position of the first space part from the tire equator surface and a tread half width TW satisfy 0<A1<0.5×TW, the diameter &phgr;1 of the first space part and a rim diameter R satisfy 0.007×R<&phgr;1<0.041×R, and the depth D1 in the extending direction of the first space part and a distance G1 in the extending direction of first space part from the installing position of the first space part to the carcass line on the outer surface satisfy 0.3×G1<D1<0.8×G1. The extending direction of the first space part passes the installing position of the first space part on the tire outer surface and exists between from the direction orthogonal to the tire axial direction to the direction orthogonal to the carcass line, and at least a part of the first space part is filled with rubber material having a modulus at 300% elongation of larger than 10 MPa and smaller than 20MP. |
