Tire/Wheel Assembly
i2 SE Tire Tube (cont.)
Installation
NOTICE
Use only Segway-approved tubes. The 90-degree bend in the
valve stem is necessary for proper clearance.
Tools Required: Tire iron
Air pump
1. To install a new tire, seat the outside bead on the
wheel by hand before installing the tube.
2. Inflate the tube with just enough air to give the tube
a circular shape.
3. Align the valve stem with the opening in the rim
and feed the tube into the tire around the rim. See
Figure 4–12. Make sure there are no kinks, bends,
or folds in the tube. Push the valve stem through the
opening in the rim.
4. By hand, work the outside bead back over the rim as
much as possible. See Figure 4–13.
5. Use a tire iron to lift the remaining bead over the rim,
being careful not to pinch or bind the tube or crack
the wheel. See Figure 4–14.
CAUTION!
To avoid pinching, keep hands and fingers away from
the bead during inflation.
6. Using an air pump with a Schrader valve attachment
(or other source of forced air), inflate the tire enough
to seat the tire beads. See Figure 4–15. It may be
necessary to overinflate the tire to properly seat the
tire beads. When properly seated, the tire and wheel
will have an even, slight gap. Ensure the tire stem is
angled 45-degrees toward the chassis.
NOTICE
If the tire becomes overinflated when seating the
beads, release air until the pressure reaches 15 psi.
7. Install the Tire/Wheel Assembly (page 4–2).
8. Perform post-service tests (page A–1).
