Abstract

A pneumatic tire includes: main grooves in a tread, extending in a circumferential direction in alignment in a lateral direction, defining a center land on an equatorial plane and middle lands on outer sides in the lateral direction; a sipe formed in the center land communicating with a center main groove and terminating within the center land, the sipe bending halfway through its length; a circumferential narrow groove in each of the middle lands dividing the middle lands into a rib-shaped middle inner land and a middle outer land; and lug grooves formed in the middle outer land in alignment in the circumferential direction, communicating with a shoulder main groove and the circumferential narrow groove and dividing the middle outer land into blocks. A width dof the middle inner land and a groove width dof the circumferential narrow groove satisfy a relationship of 0.1≤d/d≤0.4.
