2.5 Mounting Standard Tire to Rim
Always be aware of this “checklist” when mounting tires to ensure proper service.
There are four basic steps when mounting a tire to a rim:
• Position the bead on top of the left lip of mount/demount head.
• Position the bead under the right lip of the mount/demount head.
• Lock the rim to the tire.
• Slip the bead into the drop center.
These four basic steps to mounting do not necessarily follow the same sequence,
however all four steps need to be performed to mount a tire to a rim.
Mount a standard tire to rim as follows:
Lubricate inside and outside of both beads of the tire to be mounted with
supplied mounting paste.
Position tire on top of the rim and tilt tire forward toward column.
Position mount/demount head through the opening of the tire and on the outer
edge of the rim lip.
The angle between the tool arm and the rim flange must be close to 90
degrees.

The mount/demount assembly arm can be set to four different positions. The
four positions are set using the arm adjustment knob on the column and
moving the arm manually until it is locked in the required position. For rims
with flat, rounded, or painted rim lips, the angle between the tool arm and the
rim flange can be adjusted to approximately 110 degrees.
Position edge of lower tire bead on top of the left lip of mount/demount head.
Push edge of lower tire bead under the right lip of the mount/demount head
while keeping other edge of lower tire bead above the left lip.
Twist tire clockwise by hand to lock the mounting of the tire to the rim.
Push down on tire at approximately the 6 o’clock position to slip the tire into
drop center.
Rotate wheel clockwise until the lower tire bead drops over the lip of the rim.
Repeat procedure on upper bead of tire, making sure to slip the bead
completely into the drop center of the rim, during mounting of the upper bead.
