PROBLEM TO BE SOLVED: To provide a tire excellent in low heat build-up and abrasion resistance using, in a tire member, a rubber composition which particularly excels in the interaction between a rubber component and carbon black and/or silica, can more improve the dispersibility of these fillers, and contains, as a rubber component, a modified conjugated diene polymer improving particularly low heat build-up and abrasion resistance. SOLUTION: The tire uses, in a tire member, a rubber composition containing a rubber component (A) including a modified conjugated diene polymer (a-1) obtained by reacting a silane compound having a specific structure and/or a partial condensate thereof as a modifier with an active terminal group of a conjugated diene polymer having the organometallic active terminal with nucleophilic reactivity and a modified diene polymer (a-2) obtained by a specific manufacturing method at a mass ratio of 5:95 to 95:5.
