The tread portion 2 includes a crown region Cr between a tire equator C and a middle position 2c and a shoulder region Sh between a first tread ground-contact end T1 and the middle position 2c. The buttress portion Bt has a land ratio D which is a land portion ratio between the first tread ground-contact end T1 and a first position P1. A land ratio B of the shoulder region Sh is larger than a land ratio A of the crown region Cr and the land ratio D of the buttress portion Bt.",
