ABSTRACT OF THE DISCLOSURE An enclosed container having a divided chamber with an air pressure section and a liquid coolant section separated by a pressure-transmitting wall. A one-way inflation valve in the container is in communication with the air pressure section for inflation of this section. A liquid release valve in the container is in communica- tion with the liquid coolant section and is set to release liquid into a tire cavity when the tire is operated in a deflated condition. The container is of a resilient, noncollapsible material for retaining air under pressure and for gripping the rim on which the tire is mounted. The method of dispensing liquid coolant includes pouring the coolant into the liquid section, inflating the air pressure section to bleed air out of the liquid section, mounting the container on the rim with the inflation valve and release valve in communication with the tire cavity, inflating the tire to normal tire mount- ing pressure to provide liquid ejecting pressure in the air pressure section of the container, reducing the air pressure in the tire cavity to normal tire operating pressure, and releasing the liquid coolant from the liquid section upon opening of the release valve in response to reduction of the air pressure in the tire cavity to an amount below the normal operating pressure as in the event of a puncture or blowout for cooling and lubrication of the tire.
