A winter tire providing an improved traction performance on the snow. A tread (14) comprises a surface layer (21) formed of a rubber having a Shore A hardness of 50 to 56 and an inner layer (22) formed of a rubber having a Shore A hardness 2 points higher than that of the rubber of the surface layer (21). The surface layer (21) is so formed as to be thicker in the tread center region (10A) than in the tread shoulder region (10B). Thus it is made easier for sipes (18) to open in the tread center region (10A), and the rigidity in the tread shoulder region (10B) is ensured.
