Abstract

Provided is a pneumatic tire including: a plurality of land portion rows (18) formed by arranging a plurality of land portions (16) formed by main grooves and transverse grooves in a tire circumferential direction on a tire tread portion, wherein assuming a tire circumferential length of an element (20) formed of the land portion and the transverse groove disposed adjacently to the land portion on one side in the circumferential direction as a pitch length P and the number of pitches which is the number of the elements (20) over the whole circumference of the tire as N, the number of kinds k of pitch lengths P in the circumferential direction is set to N/4 or more and N or less. Assuming the pitch lengths P in a descending order as Pi, P 2 , ..., Pk, a relationship of P m-1 /P m <1.050 and a relationship of 1.60¤P 1 /P k <2.00 are satisfied (m: an integer of 2 to k).
