A method for forming a composite tread, the method comprising the steps of forming a coextruded strip of a first compound and a second compound, wherein the first compound is a tread compound, and the second compound is formed from a high-wear compound, wherein the tread is formed from winding the coextruded strip onto the tire building drum while varying the ratio of the first compound to the second compound.

Reinforced tread and method of forming

A method for forming a composite tread, the method comprising the steps of: forming a coextruded strip of a first compound and a second compound, wherein the first compound is a tread compound, and the second compound is formed from a second compound, wherein the tread is formed from winding the coextruded strip onto the tire building drum while varying the ratio of the first compound to the second compound.

Composite tread with targeted stiffness gradient and method of making

A method for forming a composite apex, the method comprising the steps of: forming a coextruded strip of a first compound and a second compound, wherein the second compound is a compound different than the first compound, wherein the apex is formed from winding the coextruded strip while varying the ratio of the first compound to the second compound.

Method and apparatus for forming an apex

A method for forming a composite tread, the method comprising the steps of: forming a coextruded strip of a first compound and a second compound, wherein the first compound is a tread compound, and the second compound is formed from a second compound, wherein the tread is formed from winding the coextruded strip onto the tire building drum while varying the ratio of the first compound to the second compound

One or more embodiments of the present invention provide an apparatus for forming a continuous strip of a first compound that is encapsulated by a second compound. The apparatus allows the mixture ratio of the first compound to the second compound to vary. The first compound may be a sealant, and the second compound may be a rubber.
