Abstract
A pneumatic tire having a pocket filled with lubricant attached to the inner sidewall of the tire having a puncture sealant surrounded by an O-ring built into the inside wall of the pocket. The puncture sealant allows lubricant to be injected into the pocket by use of a syringe and eliminates the need for subsequent sealing of the pocket and leakage of lubricant from the pocket.
