Abstract: 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.

Abstract: Provided is a run-flat support body (1) for a pneumatic tire, in which an outer peripheral side of an annular shell (2) serves as a support surface for supporting an inner surface of the tire (T); an inner peripheral side of the annular shell (2) straddles in the form of a bifurcation; elastic rings (3) and (3) are attached respectively to two leg parts (2b) and (2b) of the annular shell (2); and the annular shell (2) is supported on a rim (Rm) of a wheel with the elastic rings (3) and (3). The elastic rings (3) and (3) are composed of a composite elastic material formed by compounding reinforcement fillers in an elastic material. Accordingly, compressive rigidity of the elastic rings in a radial direction of the tire is made larger than that of the unreinforced elastic rings in the tire radial direction, the unreinforced elastic rings being composed of a single elastic material in which the reinforcement fillers are not compounded. Moreover, bending rigidity of the elastic rings in an axial direction of the tire is made substantially equal to that of the unreinforced elastic rings in the tire axial direction, the unreinforced elastic rings being composed of a single elastic material in which the reinforcement fillers are not compounded.
