Abstract

A tread portion 2 includes a plurality of circumferential grooves 3 continuously extending in a tire circumferential direction, and a plurality of land portions 4 demarcated by the plurality of circumferential grooves 3. The plurality of land portions 4 include at least one pattern land portion 6 on which axial grooves 5 are arranged in the tire circumferential direction with a number of pitches N so as to extend in a tire axial direction. In a load-applied state where a load that is 80% of a standardized load is applied in a state where a pneumatic tire 1 is fitted on a standardized rim and adjusted to a standardized internal pressure, a ground-contact surface shape of the tread portion 2 has a first tread end Te1, a second tread end Te2, and a first ground-contact end edge 7 extending from the first tread end Te1 to the second tread end Te2 on one side in the tire circumferential direction. A first straight line 7a connecting both ends in the tire axial direction of a portion, of the first ground-contact end edge 7, traversing the pattern land portion 6 satisfies a predetermined formula (1).
