A tire (100) is configured such that, when the distance between a pair of ground contact ends (11E) is a ground contact width (W), the tire (100) has shoulder regions (10S) which each constitutes a range of 0.20W to 0.30W from one of the pair of ground contact ends toward the inner side of the tire in the width direction (TW) thereof. In a cross-section of the tire taken in the width direction (TW) and radial direction (TR) of the tire, the tread profile which is the outer shape of the shoulder regions (10S) is defined by N radii of curvature (SR(n)) (n = 1 to N), the N radii of curvature being arranged sequentially from the inner side of the width direction (TW) of the tire. N and the radii of curvature (SR(n)) satisfy the conditions of N ‰¥ 3 and SR(n) / SR(n + 1) ‰¤ 3. |
