Step 1: Put your tire on a flat surface, and then measure from the surface to the bottom of
the lug nut hole. You need this to determine the height of the tire mount.
Step 2: Once you have this measurement, mount the side plates to the tire mount, and adjust
the height of the top of the tire mount, so its ¼” less than the measurement you took
earlier.
Step 3: Now mount the tire mount to flooring as shown in picture, making sure there is
enough room around it so the tire will fit flat on the flooring.
Step 4: Install tire. Make sure that there is not too much, so the tire compresses slightly,
without bending the flooring tubes, or the mount.
