The land regions include a crown land region (10) and a first middle land region (11). The crown land region has a plurality of crown lateral grooves (15). The first middle land region has a plurality of first middle lateral grooves (20). In a tread plan view, an angle between a first linear line (21) connecting both ends of each of the crown lateral grooves (15) and a second linear line (22) connecting both ends of a respective one of the first middle lateral grooves (20) is 90 degrees or more and 150 degrees or less. Each of the crown lateral grooves (15) includes a first end portion (16), a second end portion (17), and a center portion (18). The center portion (18) has a groove width smaller than a groove width of the first end portion and a groove width of the second end portion.",
