<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire having small variations in fastening force and excellent rim assemblability.SOLUTION: A tire 2 includes: a pair of beads 6; a carcass 8; a chafer 16; insulations 12; and cushion layers 14. The bead 6 has a core 18 positioned within the bead 6 and positioned on the inner side in tire 2 radial direction. On the inner side in tire 2 radial direction than a core 18, the insulation 12 is laminated on the radial outside of the chafer 16. The cushion layer 14 is laminated on the radial outside of the insulation 12. The insulation 12 and the cushion layer 14 are formed of different types of cross-linked rubbers, respectively. A compression modulus Eαof the cross-linked rubber of the cushion layer 14, is set smaller than a compression modulus Eβof the cross-linked rubber of the insulations 12.</p> |
