Abstract

Provided is a tire with excellent overall performance in terms of abrasion resistance, wet grip performance, and bleed resistance. The present invention relates to a tire which includes a tread including a rubber composition that contains a rubber component and a branched conjugated diene polymer, wherein the branched conjugated diene polymer is a copolymer at least containing a branched conjugated diene, butadiene, and styrene as structural units, and the tire satisfies the following relationships (1) and (2): Relationship (1): 0.25 < A ≤ 1.50; and Relationship (2): A × S ≤ 27.0, wherein A is defined by A = 42.9/√α + 0.14 wherein α represents the weight average molecular weight of the branched conjugated diene polymer; and S represents the groove area ratio (%) of the ground contact surface of the tread.
