TIRE

Provided is a tire (2, 202, 302, 402, 502, 582, 622) that can achieve the improvement in a visual aspect. A tire (2, 202, 302, 402, 502, 582, 622) has an outer diameter smaller than a value obtained by subtracting 4 mm from an outer diameter maximum value of new product dimensions defined by a JATMA standard or an ETRTO standard, and has a total width smaller than a value obtained by subtracting 5 mm from a maximum total width of the new product dimensions. The tire (2, 202, 302, 402, 502, 582, 622) includes an outer surface (2G, 202G, 302G, 402G, 502G, 582G) including a tread surface (24, 220, 324, 424, 524) and a pair of side surfaces (28, 224, 328, 428, 528, 600). The tread surface (24, 220, 324, 424, 524) includes an equator (PC) that is an intersection point with an equatorial plane. Each of the side surfaces (28, 224, 328, 428, 528, 600) includes a maximum width position (PW). In a normal state, a ratio (LSh/LBS) of a length (LSh) of the shoulder line segment to a length (LBS) of the reference line segment is 85.9% or more and 89.3% or less, and a ratio (Rc/Rm) of the radius (Rc) of the center arc to the radius (Rm) of the middle arc is 1.85 or more and 2.00 or less.
