<p>A tire for a construction vehicle, having less troubles. This is achieved by increasing heat radiation ability of a tire center section. The tire for a construction vehicle has lug grooves (22) placed in tread shoulder regions on both sides in the width direction of the tire. Also, fine grooves (24) are formed in a tire center section (C). The fine grooves (24) are substantially in the tire width direction, and inner ends in the tire width direction of the fine grooves (24) end in a tread. By this, reduction in land section rigidity is suppressed to improve abrasion resistance and, at the same time, heat radiation ability of the section can be enhanced. Further, an equator shallow groove (26) extending in the circumferential direction of the tire is placed at a tire equator (CL). This can ease compression stress acting in the tire center section (C) and can increase the heat radiation area.</p> |
