A pneumatic tire comprising a reinforcing structure (32a, 32b, 54) comprising a layer of knitted fabric (300) comprising a first yarns (310) and second yarns (320) is disclosed. Preferably, the reinforcing structure (32a, 32b, 54) is a flipper and provides a buffer for absorbing shear strain.
摘要:
A pneumatic tire comprising a tread (52) comprising a tread surface which is designed to be ground contacting when the tire (50) is operated on a vehicle is disclosed. The tread surface comprises a rubber composition comprising a diene based elastomer and fibers (102), the fibers (102) extending lengthwise in an at least substantially axial direction (106) of the tire (50).
摘要:
This invention relates to a farm tire, especially a farm tractor drive tire, with a tread having a running surface of significantly spaced apart lugs designed to be soil engaging of a rubber composition comprised of at least one conjugated diene-based elastomer which contains an organosilane polysulfide in situ coupled dispersion of reinforcing filler as a pre-formed starch/plasticizer complexed composite. The running surface of the farm tire tread itself is of a configuration comprised of widely spaced apart raised lugs to provide a ratio of net running surface of the tread lugs to the tread's gross dimensions (net to gross ratio expressed in terms of percentage of the running surface of the lugs) in a range of from 15 percent to 20 percent. Therefore, operationally in the field, normally few lugs actually touch, or engage, the ground at any one time. Accordingly, such individual tread lugs are desirably capable of experiencing locally high loads and should be sufficiently stiff to resist extensive elongations.
摘要:
A pneumatic tire having a radially outer circumferential rubber tread (2), a carcass (5) and a layered composite (6) of at least one sealant layer (7) and at least one air permeation resistant film layer (8) is disclosed. The layered composite (6) comprises a sealant layer (7) on its radially outer side positioned adjacent to the carcass (5). The sealant layer (7) supports an air permeation resistant film layer (8) on its radially inner surface. The sealant layer (7) comprises an organoperoxide depolymerized butyl rubber, or a polyurethane. The air permeation resistant film layer (8) comprises a thermoplastic material containing a dispersion of elastomer domains wherein the thermoplastic material comprises nylon and wherein the elastomer domains comprise at least one of butyl rubber and sulfur curable diene-based elastomer domains.
