A safety cage device is disclosed for use in restraining a multiple part rim during the inflation of a truck tire. The safety device comprises a base having a pair of outwardly extending arms and a shaft which extends through the center of the rim, and a retainer which fits on the shaft and has outwardly extending arms to hold the top of the rim. If the rim explodes, a portion of the retainer inelastically deforms to absorb the force of the explosion. The energy-absorbing deformation of a portion of the device allows other portions of the device to do a better job of retaining the various parts of the rim.
