A tire (10) includes: a pair of bead portions (12) in which a bead core (18) is each embedded and that have a bead heel diameter (DH) that is from 0.42% to 0.72% smaller than a rim diameter (DR) of a standard rim (30); a carcass (22) that spans a region between the pair of bead portions (12) and that has end portion sides anchored to the bead cores (18); bead filler (20) that extends from each bead core (18) toward a tire radial direction outer side so as to run along an outer face (220) of the carcass (22); and side reinforcing rubber (26) that is provided at tire side portions (14), that extends in the tire radial direction along an inner face (22I) of the carcass (22), that has an end portion (26B) at each bead core (18) side overlapping the bead filler (20) with the carcass (22) interposed therebetween, and that has elongation at break of 130% or greater. |
