Abstract

PURPOSE:To obtain the captioned tire for a midget bogie car which has good roadability on the normal road in such a way that the angle of rake on the revolving leading side is formed by protruding flags which have snow-hardening blade profiles in hollow triangles more than equal to the angle of rake on the trailing side radiately along the circumference of the tire. CONSTITUTION:When a vehicle runs on the snow surface S, rake planes 17 on the revolving leading side and blade profiles 22 hit the snow surface S. Then, since the inside of the rake parts 17 is hollow, and the blade profiles 22 have indents 20, they elastically deform, dynamic lift works by reaction force which is applied from rake parts 18, supporting parts of the blade profiles 22, etc., pressing action is worked on the snow surface s, and a large area of road surface can be formed. And when they leave the road surface s, they restore by their elastic force and the reaction force at the rake planes 18 and at the other supporting parts. Such a constitution helps it run not alone on the snow surface but also on the normal road.
