A method of retreading a tire. The method includes the steps of applying a primer to an inner surface of a circumferential tread and applying the primer to an outer surface of a tire casing; applying an adhesive to the primer disposed on the inner surface and the primer disposed on the outer surface; applying the circumferential tread to the tire casing so the inner surface contacts the outer surface and a bondline edge forms circumferentially about the tire casing proximate to a shoulder area of the tire casing; and coupling a moisture reservoir to the circumferential tread proximate to the bondline edge.

Use of a moisture reservoir for retreading

A carbon black pellet comprising a plurality of agglomerates, aggregates, or primary carbon black particles and a binder including a functional polymer.

Carbon black pellets bound by functional polymer

A method of manufacturing a tread for agricultural tires, the method comprising providing an agricultural tire casing, providing a cured rubber component having first and second planar surfaces, providing a plurality of cushion gums, wherein the plurality of cushion gums contains a cure system comprising a stable dinitrile oxide compound, providing a plurality of lugs, and forming an agricultural tread composite by mating the lugs to a planar surface of the cured rubber component using the cushion gum.

A method of preparing a precured tire tread includes forming a green tire tread strip having a top surface and a bottom surface. The method also includes curing the green tire tread strip to form a precured tire tread having a top surface and a bottom surface. The method further includes abrasive blasting the bottom surface of the precured tire tread, air blasting the bottom surface of the precured tire tread, and washing the bottom surface of the precured tire tread with a liquid.

Method of preparing a bottom surface of a precured tire tread

A carbon black pellet comprising a plurality of agglomerates, aggregates, or primary carbon black particles and a binder including a hot-polymerized styrene-butadiene copolymer.

A retreaded tire assembly and method for making the same is disclosed. The method and assembly provide for the application of new tread to a buffed tire casing with only a layer of cushion gum disposed therebetween. The cushion gum is applied directly to the buffed circumference of a tire casing without the use of conventional spray cement normally applied to the buffed surface of the entire casing.

Retreaded tires and method for making the same without spray cement

A method and adhesive system for bonding at least two elastomeric substrates together. The method comprises subjecting the substrates to a priming treatment followed by applying to the primed substrates a heat-curable polyurethane adhesive composition comprising an isocyanate-terminated prepolymer and a polyhydroxide compound. The surfaces of the substrates so treated are contacted and subjected to heat-curing to bond the substrates together.

Tire bonding systems

Method for forming a composite elastomer tire tread by applying a heat curable liquid elastomer mixture to a thin rubber sheet and curing the liquid mixture to form the composite tire tread. A tire retreaded with such a composite tire elastomer tread is also described.
