摘要： A method and a device for fixing a run flat support body to a pneumatic tire capable of avoiding the deterioration in the weight balance of wheels by preventing a lubricant applied to the inner surface of the tire from being nonuniformly distributed when the run flat support body is used. In the fixing method, the run flat support body formed of a pair of elastic rings disposed around a rim and an annular shell installed across these elastic rings is fixed to the pneumatic tire to which the rim is fitted while the run flat support body is inserted into the hollow part of the tire. The fixing device for restricting the radial movement of the run flat support body inserted into the hollow part is fitted to at least one of the bead parts of the pneumatic tire before the rim is fitted thereto to coaxially hold the pneumatic tire and the run flat support body (3) by the fixing device.

摘要： A pneumatic tire in which a sealant layer has been formed based on a decomposition reaction of polyisobutylene and which has an excellent puncture-preventing function while avoiding any inconvenience aroused by the sealant layer formation. The pneumatic tire has a sealant layer in that region of the inner surface of the tire which corresponds at least to the tread. The sealant layer is made of a pressure-sensitive adhesive sealant obtained by heating a rubber composition containing 0.2 to 20 parts by weight of a peroxide per 100 parts by weight of a rubber ingredient comprising at least 50 wt.% of polyisobutylene and 0.2 to 20 parts by weight of a peroxide. A liquid ethylene/α-olefin copolymer, liquid polybutadiene, or liquid polyisoprene is added as a pressure-sensitive adhesive for the sealant layer in an amount of 5 to 50 parts by weight.

The run-flat support body of the present invention comprises a pair of elastic rings fitted to a rim of a wheel and an annular shell bridging between these elastic rings. In the run-flat support body, the elastic rings and the annular shells are integrally joined, at least one discontinuous spot is provided in a circumference of the annular shell and the elastic rings, a connection structure is formed in which butted ends of the annular shell are joined together by welding, and joining between the annular shell and the elastic ring is partially released in the vicinity of a butted position of the annular shell. When the run-flat support body is inserted into a cavity portion of a pneumatic tire and the butted ends of the annular shell are joined together by welding, the welding work on a portion covered by the elastic ring is performed in a state where the elastic ring is retreated from the butted position of the annular shell.

摘要： A process in which a self-sealing pneumatic tire consisting of a pneumatic tire after vulcanization molding furnished with a sealant layer being uniform without thickness irregularity and a cover sheet layer therefore is produced without the use of an organic solvent and expensive apparatus; and an apparatus therefore. The process is characterized by sequentially performing the operations of injecting a viscous sealant material onto the internal surface of a pneumatic tire (T) after vulcanization molding; diffusing the sealant material into a sheet form by centrifugal force while rotating the pneumatic tire (T) around the tire axis to thereby form a sealant layer (11); injecting a cover material of uncured rubber material or resin material onto the inside surface of the sealant layer (11); diffusing the cover material into a sheet form by centrifugal force while rotating the pneumatic tire (T) around the tire axis to thereby form a cover sheet layer (12); and irradiating the cover sheet layer (12) with electron beams, infrared rays, ultraviolet rays or ultrasonic waves to thereby harden the same.
