Remove and repair all penetrating objects and check the beads for damage that may have occurred during removal. If none of these conditions exist, the Rubber Manufacturers Association (RMA) suggests the following procedure for returning the tire to service. 1) Place the tire/wheel assembly in an approved inflation safety cage*. Remain outside of the tire’s trajectory. Do not place hands in the safety cage while inspecting the tire or place head close to the safety cage. After properly seating the beads, with the valve core removed, adjust the tire to 20 psi, using a clip-on air chuck with a pressure regulator and an extension hose. Penetrating Objects 2) Inspect the mounted tire inflated to 20 psi for distortions or undulations (ripples and/or bulges). Listen for popping sounds. IF ANY OF THESE CONDITIONS ARE PRESENT, THE TIRE SHOULD BE MADE UNUSABLE AND SCRAPPED. If none of these conditions are present, proceed to the next step. 3) With the valve core still removed, inflate the tire to 20 psi over the normal recommended operating pressure. During this step, if any of above conditions appear, immediately stop inflation. DO NOT EXCEED MAXIMUM PRESSURE SPECIFICATION FOR THE WHEEL. Bead Damage Caused by Mounting/Dismounting 4) Before removing the tire/wheel assembly from the safety cage, reduce the inflation pressure to the recommended normal operating pressure. Remain outside of the tire’s trajectory zone. * Occupational Safety and Health Administration Standard 1910.177 requires all tubeless and tube-type medium and large truck tires be inflated using a restraining device or barrier (e.g., safety cage that conforms to OSHA standards), and using a clip-on chuck with a pressure regulator and an extension hose.
