PROBLEM TO BE SOLVED: To provide a retreaded tire that can improve the durability performance of the tire.SOLUTION: In this retreaded tire 10, a tread width TW and a tire total width SW have the relation expressed by 0.65≤TW/SW≤0.90. Additionally, a distance SDH in a tire radial direction from a rim diameter measurement point P to a tire maximum width position Q and a tire cross-section height SH have the relation expressed by 0.45≤SDH/SH≤0.65. Additionally, if the foot of a perpendicular L1 drawn to a tread profile from the point E of the edge part of an intersection belt 141, 142 located radially outside the tire is R1, and the intersection of the profile of a buttress part and a straight line L2 passing through the point E and extending perpendicular to the perpendicular L1 is S1, a distance A1 from the point E to the point R1 and a distance from the point E to the point S1 have the relation expressed by 0.90≤B1/A1≤1.50.SELECTED DRAWING: Figure 4
