TIRE

A tire can include a tread portion and a buttress portion. The tread portion can include a crown region between a tire equator and a middle position and a shoulder region between a first tread ground-contact end and the middle position. The buttress portion can have a land ratio which is a land portion ratio between the first tread ground-contact end and a first position. A land ratio of the shoulder region can be larger than a land ratio of the crown region and the land ratio of the buttress portion.
