TIRE FOR CONSTRUCTION VEHICLE

摘要

A tire for a construction vehicle, in which a rise in temperature at a tread portion is suppressed by enhancing heat radiation properties at a tire center portion. Lug grooves (22) are provided in tread shoulder regions S on both sides in the width direction of the tire. Also, the tire has, in a tire center portion C, narrow grooves (24) extending substantially in the tire width direction V and having both ends terminating within the tread. Furthermore, the tire has a deep equator groove (26) extending in the tire circumference direction on a tire equator surface CL and having a maximum depth in the range of 70 to 110% of the depth of thelug groove (22). Consequently, the bottom (26B) of the deep equator groove (26) in high temperature can be cooled efficiently.
