ABSTRACT:
This disclosure relates to a fluid reservior and dispensing means and pneumatic tire-rim combination containing the reservoir and dispensing means. The reservoir is a hollow annular structure adapted to be located in the drop center area of the rim. The dispensing means is a breakable valve attached to the reservoir which is so situated in the tire cavity that it will be fractured by the tire when the tire is run uninflated thereby releasing the fluid into the tire cavity.
