PROBLEM TO BE SOLVED: To provide a tire excellent in low heat generation property and heat resistance. SOLUTION: In the tire, a rubber composition, in which a heat-resistant crosslinking agent is formulated in a rubber component containing a modified conjugated diene polymer having a cis-1,4 bonding amount of 90% or more, a vinyl bonding amount of 1.2% or less, and a primary amino group, is used for any tire member. Here, the heat-resistant crosslinking agent can form a crosslinking structure by a bond other than a disulfide bond and a polysulfide bond. Further, the tire members preferably include a tread part 1, a sidewall part 2, a side reinforcement rubber layer 8, and a bead filler 7. COPYRIGHT: (C)2011,JPO&INPIT
