Abstract
Abstract A solid rubber tire comprised of rubber or plastic having elastomeric properties has a bottom layer and a tread portion connected to the bottom layer. A reinforcement structure for the bottom layer is provided in the form of a textile reinforcement element or a metal reinforcement element. The reinforcement structure is a wound overlay having at least one reinforcement layer which is produced by winding the reinforcement element in a plurality of windings so as to extend over at least 20% of the axial width of the bottom layer. The reinforcement element can be a cord, wire or cable. The reinforcement element may also be a cord material strip having individual reinforcement members arranged in parallel. The reinforcement members can be textile or metal reinforcement members in the form of cord, wire or cable. A method for producing the solid rubber tires is disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A solid rubber tire comprised of a material selected from the group consisting of rubber and plastic having elastomeric properties, said solid rubber tire comprising: a bottom layer; a tread portion connected to said bottom layer; a reinforcement structure for said bottom layer, said reinforcement structure comprised of a reinforcement element selected from the group consisting of textile reinforcement elements and metal reinforcement elements; said reinforcement structure being a wound overlay having at least one reinforcement layer consisting of one said reinforcement element wound in a plurality of windings and extending over at least 20% of an axial width of said bottom layer; said reinforcement element selected from the group consisting of cord, wire, and cable; and wherein a spacing between adjacent ones of said windings within said at least one reinforcement layer varies.
Claim 2
Dependent Claim
134 words
A solid rubber tire comprised of a material selected from the group consisting of rubber and plastic having elastomeric properties, said solid rubber tire comprising: a bottom layer; a tread portion connected to said bottom layer; a reinforcement structure for said bottom layer, said reinforcement structure comprised of a reinforcement element selected from the group consisting of textile reinforcement elements and metal reinforcement elements; said reinforcement structure being a wound overlay having at least one reinforcement layer consisting of one said reinforcement element wound in a plurality of windings and extending over at least 20% of an axial width of said bottom layer; said reinforcement element selected from the group consisting of cord, wire, and cable; and wherein a spacing between adjacent ones of said windings within said at least one reinforcement layer varies.
