The carcass ply 42 includes a plurality of carcass cords 44 and a topping rubber 46. Each carcass cord 44 has a total fineness of not less than 6000 dtex and not greater than 9000 dtex. The insulation 22 is located between first and second beads 10. A ratio (ta/td) of a thickness ta of the topping rubber 46 located between the insulation 22 and the carcass cords 44 to a thickness td of the insulation 22 is not less than 0.2 and not greater than 0.6.
