Abstract
A non-inflatable tire comprises a rim, an inner tire layer made of foamed material, and an outer tire layer formed by rotational molding or injection molding to encircle the rim and having at least an injection orifice at a side surface thereof for injecting material of the inner tire layer, wherein the material of the inner tire layer is injected into and foamed in the outer tire layer to form the inner tire layer such that the outer tire layer, the inner tire layer, and the rim are tightly connected with one another. A manufacture method of the non-inflatable tire comprises the steps: producing a rim, inserting the rim into a die and forming an outer tire layer having at least an injection orifice at a side surface thereof for injecting material of an inner tire layer by rotational molding or injection molding, injecting the material of the inner tire layer through the injection orifice of the outer tire layer, and foaming the material of the inner tire layer to make the outer tire layer, the inner tire layer, and the rim be tightly connected with one another.
