发明名称 PNEUMATIC TIRE
摘要 A pneumatic tire includes a tread portion provided with circumferentially extending main grooves and lateral grooves. The main grooves include an inboard shoulder main groove, an outboard shoulder main groove, an inboard center main groove and an outboard center main groove. The lateral grooves includes a plurality of first outboard shoulder lateral grooves each having an axially inner end positioned between the outboard shoulder main groove and the outboard center main groove, and a plurality of first inboard shoulder lateral grooves each having an axially inner end positioned between the inboard shoulder main groove and the inboard center main groove, wherein the number of the first inboard shoulder lateral grooves is greater than the number of the first outboard shoulder lateral grooves.
