The carcass ply can include a plurality of carcass cords and a topping rubber. Each carcass cord can have a total fineness of not less than 6000 dtex and not greater than 9000 dtex. The insulation can be located between first and second beads. A ratio (ta/td) of a thickness to of the topping rubber located between the insulation and the carcass cords to a thickness td of the insulation can be not less than 0.2 and not greater than 0.6.
