Abstract

A method of making a tire includes placing substantially circular sheets of polymeric material on top of each other until a tire is built to a predetermined width. A predetermined tread shape is formed along a circumference of the substantially circular sheets of polymeric material.

Claims9

Dependent claims

A method of making a tire comprising:

providing a first substantially circular sheet of polymeric material having a thickness in the axial direction between 0.02 mm and 2 mm;
forming a first predetermined tread shape along a circumference of the first substantially circular sheet of polymeric material, the first predetermined tread shape including a shape defining at least one of lugs, blocks, grooves, ribs, and sipes;
providing a second substantially circular sheet of polymeric material having a thickness in the axial direction between 0.02 mm and 2 mm;
forming a second predetermined tread shape along a circumference of the second substantially circular sheet of polymeric material, the second predetermined tread shape including a shape defining at least one of lugs, blocks, grooves, ribs, and sipes;
placing the second substantially circular sheet of polymeric material on the first substantially circular sheet of polymeric material after the step of forming the second predetermined tread shape along the circumference of the second substantially circular sheet of polymeric material;
providing additional substantially circular sheets of polymeric material;
forming a predetermined tread shape along a circumference of a plurality of the additional substantially circular sheets of polymeric material, the predetermined tread shape including a shape defining at least one of lugs, blocks, grooves, ribs, and sipes;
placing the additional substantially circular sheets of polymeric material on the second substantially circular sheet of polymeric material after the step of forming the predetermined tread shape along the circumference of the plurality of the additional substantially circular sheets of polymeric material, until a tire is built.
