Abstract: A tire 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 includes an outer surface including a tread surface and a pair of side surfaces. The tread surface includes an equator. Each of the side surfaces includes a maximum width position. In a normal state, a ratio of a length of the shoulder line segment to a length of the reference line segment is 85.9% or more and 89.3% or less, and a ratio of the radius of the center arc to the radius of the middle arc is 1.85 or more and 2.00 or less.

Abstract: A tyre includes a tread portion having an outer shoulder main groove, a crown main groove, and an outer middle land region defined between the outer shoulder main groove and the crown main groove. The outer middle land region is provided with first middle sipes each extending inwardly in a tyre axial direction from the outer shoulder main groove to have an inner end in the outer middle land region and second middle sipes each extending outwardly in the tyre axial direction from the crown main groove to have an outer end in the outer middle land region. The number of the second middle sipes is larger than the number of the first middle sipes.

Abstract: A tyre includes a tread portion including an outboard middle land portion disposed between an outboard tread edge and a tyre equator. The outboard middle land portion includes first and second longitudinal edges, outboard middle lateral grooves extending from the first longitudinal edge and having terminal ends within the outboard middle land portion, first outboard middle sipes extending from the respective terminal ends of the outboard middle lateral grooves to the second longitudinal edge, and second outboard middle sipes extending from the first longitudinal edge toward the second longitudinal edge beyond the terminal ends of the outboard middle lateral grooves and terminating within the outboard middle land portion. The outboard middle land portion is not provided with any lateral grooves that extend from the second longitudinal edge toward the first longitudinal edge to reach an axial center location of the outboard middle land portion.
