  "textContent": "An object of the present invention is to provide a pneumatic tire of which rolling resistance is reduced without impairing wear resistance. Specifically, the pneumatic tire of the present invention comprises: a tread portion; a pair of side wall portions; a pair of bead portions; a carcass constituted of at least one carcass ply extending in a toroidal shape between bead cores in the respective bead portions; a belt disposed on the outer peripheral side of a crown region of the carcass and formed by at least one inclined belt layer made of cords extending to be inclined with respect to the equatorial plane of the tire; and a tread rubber disposed on the radially outer side of the belt, wherein a ratio of BD/BW satisfies the following formula: (0.062 × tire aspect ratio - 0.01) < BD/BW < (0.062 × tire aspect ratio + 0.004), provided that BD is a difference in radial distance measured from the rim diameter line between the maximum-radial distance position and a widthwise end edge position of the outermost layer of the inclined belt and BW is a width of the outermost inclined belt layer in a meridian cross section of the tire in a state where the tire is assembled with an application wheel rim.",
