Abstract: A process for connecting and removing a mounting disk having holders for vehicle wheel rims in the mounting or removing of tires from the rim includes the use of a tire mounting device having a rotatable pin. The mounting disk and the rotatable pin are connnected together by a separable sliding splined connection. Wheel rims are releasably connected to the disk for the mounting of tires onto or the removing of tires from the wheel rims. The rims are made of various materials and have various designs, diameters and widths. Connections are without restrictions pertaining to the maximum possible clamping jaw diameter of the disk and without risk of damaging the wheel rim. The mounting disk functions to secure fragile wheel rims and the disk is easily connected to the tire mounting device.
