TIRE/RIM ASSEMBLY AND HOLLOW PARTICLES
First Claim
1. A tire/rim assembly constructed by assembling a tire onto a rim, arranging a number of hollow particles each consisting of a continuous phase of a thermally expandable resin and a closed cell(s) in a tire chamber defined by the tire and the rim and further filling a high-pressure gas exceeding an atmospheric pressure in the tire chamber, characterized in thatat least a part of the surface of the hollow particle has a coating fixed to the surface by heating.

Abstract
There is provided, in a tire/rim assembly, in which hollow particles are filled in a tire chamber, in order to reform the surface of the hollow particles and to prevent the hollow particles from adhering with each other, in applying coating to the surface of the hollow particles, a method for even distribution of the coating on the surface of the hollow particles and the robust fixing to the surface.
In a tire/rim assembly constructed by assembling the tire onto the rim, arranging a number of thermally expandable hollow particles consisting of a continuous phase of a resin and a closed cell(s) in the assembly and filling high-pressure gas exceeding an atmosphere pressure in the tire chamber, at least a part of a surface of the hollow particles has a coating fixed by heating the surface.

22. A hollow particle arranged in a tire chamber defined by a tire and a rim in a tire/rim assembly constructed by assembling the tire onto the rim together with a high-pressure gas exceeding an atmospheric pressure and consisting of a continuous phase of a thermally expandable resin and a closed cell(s), characterized in that
a pressure in a hollow part of the hollow particle is not less than the atmospheric pressure and at least a part of a surface of the hollow particle has a coating fixed to the surface by heating.
