CHAPTER THREE
Inspection, Adjustment & Lubrication
3. Roll the tire, along with both beads, so the
second bead is at the bottom of the rim well
(Figure 3.10.3). This provides some slack in the
beads.
4. Finish installing the second bead.
To inflate a tubeless tire
Note: To help remove any gaps between the tire beads and rimstrip,
hold both beads, adjacent to the valve stem, up and out of the center
channel with your fingers.
1. Begin to inflate the tire, filling it as rapidly as
possible to about 60PSI (4 ATM), until the tire
beads snap into the rim hooks (Figure 3.10.4).
Most tires have lines or marks running around
the casing, just above the bead. When the tire
is correctly installed, these lines are at an even
distance from the rim.
2. When the beads are correctly seated all around
the rim, inflate (or deflate) the tire to the desired
pressure.

WARNING
If a tubeless tire has insufficient air pressure it could lose
air suddenly causing you to lose control and fall. Always ride
with tubeless tires inflated to a minimum of 30PSI (2 ATM.)
To remove a tubeless tire
On tubeless-compatible rims the bottom of the
well is too narrow for both beads to rest fully
against the rim bottom at the same time, so the
tire must be rolled to "stack" the beads and get one
bead at the bottom.
1. Let all the air out of the tire.
