A tire excellent in low heat generation and heat resistance is provided. A heat-resistant crosslinking agent is blended with a rubber component containing a modified conjugated diene polymer having a primary amino group and a cis-1,4 bond content of 90% or more and a vinyl bond content of 1.2% or less. A tire comprising the rubber composition formed in any one of tire members. Here, the heat-resistant crosslinking agent can form a crosslinked structure by a bond other than a disulfide bond and a polysulfide bond. As the tire member, a tread portion 1, a sidewall portion 2, a side reinforcing rubber layer 8, and a bead filler 7 are preferable. [Selection] Figure 1 |
