Installing Tire
1. To mount a new or repaired tire,
lubricate the inside and
outside both tire beads.
2. Push the lower bead onto the rim as far
as it will go without forcing it.
See Figure G.
Figure G
Note: With proper use of tire mounting
lubricant, the first bead should slide
complete onto the rim.
In cases where it does not,
use the Mounting/Demounting Tool
to install the first bead.
3. Place the cut-out center of the
Mounting/Demounting Tool over
the Locking Nut. See Figure H.
