DISMOUNTING TYRE FROM RIM
Numbers in parentheses refer to Fig. 1, unless
otherwise specified.
Note: The following instructions apply to use of hand
tools. For procedures and tooling required to dismount
the tyre from the rim using hydraulic tools, contact the
relevant tyre manufacturer.
WARNINGS
To prevent personal injury and property
damage, be sure wheel blocks, blocking
materials and lifting equipment are properly
secured and of adequate capacity to do the job
safely.
When lifting tyre from the rim, be sure the
equipment is of sufficient capacity and
properly secured to do the job safely.
1. Position the vehicle in a level work area, apply the
parking brake and shutdown the engine. Operate the
steering in both directions several times to relieve any
pressure in the steering system.
2. Block all road wheels, except the one to be raised,
and place the battery master switch in the 'Off'
position.
3. For tyre to be removed, set up jack to support
machine weight, but do not raise machine.
4. Completely deflate tyre by removing valve cap and
valve core and leave valve open to prevent trapping of
air in tyre. Check valve stem by running a piece of wire
through the stem to make sure it is not plugged. See
warning under 'Preparation For Servicing'. Tape valve
threads for protection.
5. Break outer tyre bead loose with pry bar shown in
Fig. 2.
6. Insert flat hooked end of pry bar into breaking slots
between bead seat band (17) and outer flange (15).
See Fig. 3. A pipe over the straight end of the pry bar
will increase leverage.
7. Twist pry bar toward tyre to break bead.
8. A second pry bar may be inserted in the space
between bead seat band (17) and outer flange (15).
Twist the second pry bar to maintain the space gained
by the first pry bar.

through 8. If the tyre and rim assembly is on the
vehicle, the following procedure may be used for
breaking the inner bead.
