Provided is a bias tire capable of improving durability. This bias tire comprises: a pair of bead cores; a bead filler disposed on the outside of each of the pair of bead cores in the tire radial direction; a carcass layer spanning the region between the pair of bead cores and encapsulating the bead cores and the bead filler, the ends of the carcass layer being turned up and locked in place. In the poloidal cross section, in any position in the range of 0.9-1.6 times the height of the flange of a rim into which the bias tire is fitted, the curvature of the innermost cords of the carcass layer, in terms of the widthwise direction of the tire, protrudes widthwise outward. In the poloidal cross section, in any position in the range of 1.1-1.6 times the height of the flange, the curvature of the outermost cords of the carcass layer, in terms of the widthwise direction of the tire, protrudes widthwise outward.
