TIRE

A land portion of a pneumatic tire 1 comprises a land portion 10 having groove wall 10a a second land portion 20 having a groove wall 20a. The groove walls 10a, 20a meander. A groove width of a main groove 50 changes at a predetermined repetition cycle. The main groove 50 includes: a wide groove portion 50A having a predetermined width; and a narrow groove portion 50B which is continuous with the wide groove portion and which is narrower than the predetermined width. A relationship of ¸1 > ¸2 is satisfied where ¸1 refers to an angle formed between a tire normal line RL and the groove wall 10a or the groove wall 20a forming the wide groove portion 50A and ¸2 refers to an angle formed between the tire normal line RL and the groove wall 10a or the groove wall 20a forming the narrow groove portion 50B.
