An object of the present invention is to provide a tire for a construction vehicle which suppresses a trouble of the tire by enhancing a heat-radiation characteristic of a tire center portion. A tire for a construction vehicle according to the present invention is provided with a plurality of lug grooves 22 in tread shoulder regions located at the both sides in the width direction of the tire. A plurality of widthwise-extending narrow grooves 24 extending generally along the width direction of the tire and having an end in the width direction of the tire terminated in the tread are disposed in a tire center portion C. This may improve the wear resistance characteristic and to enhance the heat-radiation characteristic by suppressing the decrease of the rigidity of the land portion. In addition, an equatorial shallow groove 26 extending in the circumferential direction of the tire is disposed on the tire equator CL. This allows the compressive stress acting on the tire center portion to be relaxed and the area for hear-radiation to be increased. |
