NON-PNEUMATIC TIRE

A non-pneumatic tire comprising a ground contacting annular tread portion (200), a shear band (300) and at least one spoke disk (400) connected to the shear band (300) is disclosed. The spoke disk (400) has two or more spokes (412) joined together by a connecting web (414, 416). Each spoke (412) has a width W and an axial thickness t and wherein the ratio of W/t is in the range of from 15 and 80 or from 30 to 60 and/or the spring rate of the spoke disk (400) is greater than the spring rate of the shear band (300).
