PROBLEM TO BE SOLVED: To provide a tire, particularly a tire for heavy loads, with improved wear resistance and low heat buildup performance by improving processability without incurring a reduction in physical properties of a rubber composition and problems on a work environment and further by improving reversion resistance of natural rubber. SOLUTION: The tire uses a rubber composition as a member which comprises a rubber component (a) consisting of at least one selected from natural rubber and a synthetic diene rubber, a silica (b) with a nitrogen adsorption specific surface area (N<SB>2</SB>SA) of 180-270 m<SP>2</SP>/g and a partial ester compound (c) of maleic anhydride and (poly)oxypropylene, wherein (b) and (c) of 0.1-10.0 pts. mass relative to 100 pts. mass of the rubber component (a) are contained.
