1. SELECTION OF PROPER COMPONENTS AND MATERIALS a. All tires must be mounted with the proper MICHELIN ® tube and flap (if required) and rim or wheel as indicated in the specification tables on Page 93. For complete tire specifications, refer to application specific data books. Nylon Plate Tube Rim Flap Valve b. Make certain that rim/wheel components are properly matched and of the correct dimensions for the tire. c. Always fit a new MICHELIN tube in a new ® mounting. Since a tube will exhibit growth in size through normal use, an old tube used in a new mounting increases the possibility of tube creasing and chafing, possibly resulting in failure. f. Always use a safety device such as an inflation cage or other restraining device that will constrain all rim/wheel components during an explosive separation of a multi-piece rim/wheel, or during the sudden release of the contained air of a single piece wheel that is in compliance with OSHA (Occupational Safety and Health Administration) standards. Do not bolt restraining device to the floor. Never stand over a tire or in front of a tire when inflating. Always use a clip-on valve chuck with an in-line valve with a pressure gauge or a presettable regulator. Additionally, ensure there is a sufficient length of hose between the clip-on chuck and the in line valve (if one is used) to allow the service technician to stand outside the trajectory path when inflating. Trajectory zone means any potential path or route that a rim/wheel component may travel during an explosive separation, or the sudden release of the pressurized air, or an area at which an airblast from a single piece rim/wheel may be released. The trajectory may deviate from paths that are perpendicular to the assembled position of the rim/wheel at the time of separation or explosion. Pinched tube d. Always install a new flap in a new mounting. A flap, through extended use, becomes hard and brittle. After a limited time, it will develop a set to match the tire and rim in which it is fitted. Therefore, it will not exactly match a new tire/rim combination. e. Always install new valve cores and metal valve caps containing plastic or rubber seals. For tires requiring O-rings, be sure to properly install a new silicone O-ring at every tire change. 94 Section Seven: Diagonal (Bias or Cross) Ply and Tube-Type NEVER WELD OR APPLY HEAT TO A RIM OR WHEEL ON WHICH A TIRE IS MOUNTED.
