Abstract:
The tire for a vehicle comprises a main body of the tire made from a rubber composite material and a rim to form a toroidal space therein, accommodates a toroidal pneumatic tube expandable due to its elasticity in the space for liquid, and the pneumatic tube has a smaller volume than that of a form obtained by depressing the space for liquid to a desired level by a road surface at the point of time when the tube is filled with air at a specified pressure required for supporting a load imposed on the tire, and the space for liquid in the depressed form which is outside of the tube is filled with liquid so that a desired ground contact area of the tire can be obtained under the load.
Abstract:
A vehicle tire in which pressurized air is charged into an air tight inside of a tire together with from 5% to 95% by volume of a fluid having a specific gravity greater than that of air based on 100% by volume of the pressurized air and from 1% to 20% by weight of one or more of fine metals of metal oxide particles, uniformly dispersed in the fluid, based on 100% by weight of the fluid, the metal ingredient of the particles being selected from the group consisting of Al, Si, Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, Pb, Ba, Mg, and Mo.Water is desirable as the fluid charged in the tire, and the highly water absorbing polymer swollen with water may be used instead of water. Running stability and the braking distance of a vehicle can be improved remarkably.
