PURPOSE:To prevent the occurrence of a lateral skid on front wheels when a car body is leaned to run during cornering and running on a slope and perform smooth and stable running. CONSTITUTION:In a small-sized snow vehicle which runs on snow through drive of a rear crawler simultaneously with drive of front wheels, both of the base 70A and a block 71A of a front tire 7A have a shape on the ground contact side in a cross section crossing an advancing direction at a right angle, the shape extending along curves 70Aa and 71Aa having a large curvature. Further, an edge is formed at each of two ends in a direction crossing an advancing direction at a right angle. Further, the block of the front tire 7A is formed in a shape in a cross section the sentral part of which is protruded toward the ground contact side. |
