Abstract

A punctured, substantially deflated pneumatic automotive tire is internally sealed using a specially designed sealant canister containing CO.sub.2 gas propellant and a tire sealant mixture. The canister sealant comprises approximately 97% by weight of an acrylic latex material which is present with the propellant under a pre-use internal pressure of about 55-65 psig. An outlet cone portion of the canister is removably connectable to the tire inflation valve, and the internal volume and pre-use pressure of the canister are related to the internal volume and normal full inflation pressure of the tire in a manner such that the canister is operative to deliver essentially its entire contents into the tire, yet only partially inflates the substantially deflated tire past its initial pressure. After the canister is disconnected from the tire inflation valve, the tire may be further inflated to its full operation pressure using a separate source of pressurized air such as a small air compressor of the conventional type having an electrical cord that may be plugged into the vehicle cigarette lighter, and an air outlet hose removably connectable to the tire inflation valve.
