PURPOSE:To provide a set snow tire for a motorcycle by which driving force and braking force can be improved on the ice or on the snow and a side slip can be prevented when riding across a rut. CONSTITUTION:A ratio Ra/Wa of a radius of curvature Ra on a surface of a tread 1a to tread width Wa of a front wheel tire Ta is set in 0.6-0.7, and a longitudinal sipe 5a extending in a circumferential direction of a tire is arranged in the block 4a, and a rate of this longitudinal sipe 5a to the whole sipes is set not less than 70%. In addition to it, a ratio Rb/Wb of a radius of curvature Rb on a surface of a tread 1b to tread width Wb of a rear wheel tire Tb is set not less than 1.1, and a lateral sipe 5b extending in a tire width direction is arranged in the block 4b, and length of this lateral sipe 5b is set not less than 70%. |
