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.
