This run-flat tire has a reinforcement rubber layer 50 disposed on a sidewall 12, wherein: a part of the reinforcement rubber layer 50 is disposed inside a bead filter 22 in the tire width direction; in a cross-sectional view in the tire width direction, a tire radial length Hb from a tire radial outer end 22A of the bead filler 22 to a tire radial inner end 50B of the reinforcement rubber layer 50 is 70% or more of a tire radial length Ha from the tire radial outer end 22A of the bead filler 22 to a tire radial inner end 22B of the bead filler 22; and within a range from the tire radial outer end 22A of the bead filter 22 to the tire radial inner end of the reinforcement rubber layer 50, a variation range of the total thickness obtained by summing the thickness of the bead filter 22 and the thickness of the reinforcement rubber layer 50 is 10% or less.",
