TIRE REMOVAL
NOTE:
Tire must be removed or installed from the valve stem side of the rim.
1.
Remove the tire and wheel assembly from the vehicle as instructed above.
2.
Remove the valve cap and valve core and allow air to escape from the tire.
3.
If possible, use a tire machine to remove the tire from the rim.
3.1. If a tire machine is not available, loosen both tire beads by applying pressure to the tire side walls and
pushing the tire bead away from the rim flange and into the rim well
(
Figure 8-1, Page 8-2,
Detail A)
.
3.2. With the valve stem side of the wheel up, use a tire tool to carefully start the upper bead over the edge of
the wheel rim ( Figure 8-1, Page 8-2, Detail B).
CAUTION
• To avoid damage to the tire, do not use excessive force when starting the bead over the edge of the rim.
4.
When top bead is free of the rim, pull the bead from the bottom side of the rim up into the upper part of the rim
well. Insert the tire tool under the lower bead as shown ( Figure 8-1, Page 8-2, Detail C) and carefully pry the
lower bead over the rim flange.
5.
Once the lower bead is started over the rim flange, the tire can be removed from the rim by hand.
