Abstract
A tire, wherein, in a cross section in the tire width direction thereof in a state where the tire has substantially not been inflated with no load applied thereon, provided that the maximum height in the tire radial direction of the carcass is h, a radius of curvature of the carcass within a height range 0.91 h-h measured from the radially innermost position of the carcass is R7, an acute inclination angle specifically defined in the height range 0.91 h-h is θ7, the intermediate value of a radius of curvature in the height range 0.82 h-0.91 h is R6, a radius of curvature in the height range 0.63 h-0.82 h is R5, and an acute inclination angle specifically defined in the height range 0.63 h-0.82 h is θ5, R7≥0.26h, θ7≥14°, R6<R7, R5>R6, and θ5≤23°.
