The studless tire has a tread comprising specific short fiber or plate-like material dispersed in diene rubber so as to be oriented in the tread thickness direction, wherein when measured at 25null C. the tread has a complex elastic modulus E1 in the tread thickness direction, and the sheet has a complex elastic modulus Enull in the extrusion direction and a complex elastic modulus Enull in a 90null direction from the extrusion direction, when the rubber composition is made into 2 mm sheets with a roller and these moduli fulfill the following equation, 60null(E1nullEnull)/(EnullnullEnull)null100null100 and the tread has a specific tread rubber hardness. The tire is obtained using a tread prepared by extruding a rubber composition containing diene rubber and specific short fiber or plate-type material in a tube shape, thereby orienting the short fiber in the circumferential direction of the tube shaped rubber, then cutting the obtained rubber sheet parallel to the extrusion direction, rotating each piece 90null and laminating.

Abstract: A removable track for an annular resilient tire having a plurality of elongated transversely extending traction shoes mounted on a belt at spaced-apart positions along the belt. Each of the shoes has a plurality of raised traction bars at the end portions of the shoes and a central raised traction bar at a central portion of the shoe. The traction bars extend generally in a direction from one end of the shoe to the other end with the end bars being positioned on the shoe at a distance from a side edge less than the distance of the central bar from the side edge to provide a flex area for cleaning of the shoes. The traction bars at the ends of the shoes may include transverse bars to reinforce the ends of the shoes and angular bars at an acute angle to the side edges to provide traction in the lateral direction.
