TIRE
DRIVE
February 8, 2017
A tire (10) includes, in a tread surface (11): at least two circumferential grooves (12, 13) extending in a tire circumferential direction; and a land portion (14) sandwiched between the circumferential grooves (12, 13). The land portion (14) has a resonator (15) including: an air chamber (16); a first branch groove (17); and a second branch groove (18). The two circumferential grooves consist of: a first circumferential groove (12) having a smaller cross-sectional area in a cross section along a plane perpendicular to extending direction of the circumferential grooves; and a second circumferential groove (13) having a larger cross-sectional area in a cross section along a plane perpendicular to extending direction of the circumferential grooves. A centroid (C) of the air chamber (16) is situated to a side closer to the first circumferential groove (12) with respect to a tire widthwise center (CL) of the land portion (14).
