Abstract: This disclosure relates to a pneumatic tire-rim construction which has excellent run-flat characteristics which enables the tire to be run-flat on the rim without destroying the remaining useful life of the tire. The construction comprises providing the tire-rim combination with thin-walled capsules containing a lubricant-sealant material in the tire''s inflation chamber. These capsules are crushed when the tire is run un-inflated, thereby releasing the lubricant-sealant material into the inflation chamber of the tire. This material decreases the friction between the contacting surfaces of the tire when it is run un-inflated, thereby preventing any frictional damage to the tire.
