PURPOSE:To simplify the production and to improve the wear resistance, by composing a solid tire of a toroidal outer skin section made up of a specified composition and a core of a polyurethane elastomer that is filled in the bore of the toroidal skin section. CONSTITUTION:The solid tire 1 is composed of the toroidal skin section 2 and the core 3 of a polyurethane elastomer that is filled in the bore of the skin section, which skin section 2 is made up of a composition including 10-90wt% powder rubber (e.g. a dien rubber having a particle size of 20-60 mesh) that are mixed with a polyurethane elastomer. As the core, use is made of a polyurethane elastomer having a JIS hardness in the range of 30 deg.-50 deg.. Thus, the comfortableness to drive and the durability can be improved. |
