TIRE
FIG5 is an enlarged view of a second shoulder land portion and a second middle land portion shown in FIG1
FIG5 is an enlarged view of the second shoulder land portion 6B and the second middle land portion 7B. As shown in FIG5, the second shoulder land portion 6B has a buttress surface 9B that is continuous outward of the second tread end Te2 in the tire axial direction. The buttress surface 9B is tilted in the tire axially outward direction toward the tire radially inner side, and is continuous with the sidewall portion. As shown in FIG5, the second shoulder land portion 6B does not have the longitudinal narrow grooves, which are disposed in the first shoulder land portion 6A. Thus, pitch sound generated by the shoulder lateral grooves 30 disposed in the second shoulder land portion 6B and pitch sound generated by the shoulder lateral groove 10 disposed in the first shoulder land portion 6A are allowed to become white noise, and noise performance is improved. Furthermore, in the present embodiment, when the tire 1 is mounted to a vehicle, since the second shoulder land portion 6B is disposed on the outer side of the vehicle, even if the longitudinal narrow grooves are not disposed in this land portion, anti-wandering performance is maintained.
