Abstract:
In the present invention, a carcass (40) has a main body part (41) and a folded-back part (42) folded back toward the outside in the tire width direction via a bead part (60). A bead filler is not interposed between the main body part 41 and the folded-back part (42). In cross-sections of this run-flat tire (10) in the tire width direction and the tire radius direction, side-reinforcing rubber (70) is provided to the inside of the carcass (40) in the tire width direction and has a crescent shape. At least a portion of the main body part (41), positioned further to the inside in the tire radius direction than a tire radius direction inner end (CR1) of a contact region (CR) in which the folded-back part (42) contacts the main body part (41), is provided within a central region with respect to the center, in the thickness direction, of an area ranging from the outer surface to the inner surface of the run-flat tire (10).
