Abstract:
1. A safety liner for a vehicle tire, comprising: a hollow tubular body having a one-way valve into said body; air entering said tubular body through said one-way valve causing said tubular body to resiliently expand into a toroidal shape; when subjected to a compressive force, air being forced out of said tubular body when said one-way valve is kept from closing so that said tubular body assumes a flattened circular shape; a stop means in the form of a plug selectively installable into said one-way valve, so that when said tubular body is in said flattened circular shape, said stop means may be inserted into said one-way valve thereby preventing air from entering said tubular body and retaining said tubular body in said flattened circular shape; when said tubular body is in said flattened circular shape and when said stop means is removed from said one-way valve, air enters said tubular body through said one-way valve, thereby allowing said tubular body to assume said toroidal shape; and, said safety liner insertable into the vehicle tire in said flattened circular shape, and thence expanding to said toroidal shape upon removal of said stop means, so that when the vehicle tire experiences a blow out, said safety liner remains inflated.
