A method for making a compartmentalized sealant strip and barrier assemblyhas the steps of co-extruding a barrier stripof non-sealant elastomeric material with a plurality of projecting linear extending wallsand a sealant stripwherein the sealant stripis formed on one side of the barrier stripfilling the space between the plurality of projecting wallsto form a plurality of linearly extending rows of sealantacross the transverse width of the co-extrusion to form the compartmentalized sealant strip and barrier assembly. The step of co-extruding may further include the step of: forming the projecting wallson an inclined angle relative to a plane perpendicular to the width of the assembly. The step of co-extruding further has the step of forming the barrier stripwith lateral edgesandthat extend beyond the lateral outermost sealant stripson each side of the assembly, the lateral edgesbeing bonding surfaces to seal the sealant strip and barrier assemblyinto an uncured rubber layer when assembled into an unvulcanized tire

The present invention relates to a pneumatic tire which contains a built-in zoned puncture sealant layer. The zoned puncture sealant layer is comprised of organoperoxide depolymerized butyl rubber zones comprised of a central primary zone and lateral zones joined together to form a unitary sealant layer. The sealant of the lateral zones of the sealant layer is of a higher storage modulus (G') than the sealant of the central zone.

Tire with zoned built-in sealant layer

A two-piece tire assembly has a removable tread beltfor installing about the circumference of a tire carcass. The tread belt has at least a pair of belt layers, and one layer comprising inextensible reinforcing cables inclined at substantially zero degrees relative to the circumferential direction of the tire assembly. The cables in zero degree ply have a tensile breaking load of at least 50,000 N.

Two piece tire with improved tire tread belt

A two-piece tire assembly has a removable tread belt 12 for installing about the circumference of a tire carcass 14. The tread belt has at least a pair of belt layers, and one layer comprising inextensible reinforcing cables inclined at substantially zero degrees relative to the circumferential direction of the tire assembly. The cables in zero degree ply have a tensile breaking load of at least 27500 N.

A two-piece tire assembly has a removable tread beltfor installing about the circumference of a tire carcass. The tread belt has a pair of lateral ends each axially extending beyond the inflated unloaded carcassat the circumferential surface by a distance of at least% of the width as measured at the tread beltand carcassinterface. The carcasshas an abrasion resistant rubber layerat the tread belt interface. The tread beltalso has the abrasion resistance tread compoundat the carcassinterface. The tread belthas a tread portionthat includes a tread capA and a tread baseB.

Two-piece tire with improved tire tread belt and carcass

A two-piece tire assembly has a removable tread beltfor installing about the circumference of a tire carcass. The tread belt has a pair of lateral ends each axially extending beyond the inflated unloaded carcassat the circumferential surface by a distance of at least 4% of the width as measured at the tread beltand carcassinterface. The carcasshas an abrasion resistant rubber layerA at the tread belt interface. The tread beltalso has the abrasion resistance tread compoundB at the carcassinterface.
