6．3 Tire mounting
Note: To avoid explossion in inflating, it is important to check the tire and rim. Before
mounting the tire, pay attention to the following points:
●Don’t mount the tire if the outside of tire is damaged.
●Whether the rim is dented or deformed. In particular, there will be small cracks in the rims of alloy
wheels, which cannot be seen with naked eyes, which will damage the durability of wheel, so there
will also be risks in inflating process.
●Make sure that the wheel rim and tire are of the same size. If you cann’t make sure of
it, don’t mount the tire.
●Lubricate the tire beads with special grease in order to avoid damaging them and to facilitate
the mounting operations.
●Clamp the rim firmly on the turntable.
Don’t put your hands under the tire during clamping process.
In order to clamp the rim correctly, it should be placed in central position
about the wheel on the turntable.
Before operating the column tilting, make sure that there is nobody standing
behind the column.
13
Note: When working with the rims of the same size, it is not necessary always to lock and unlock
the mounting bar, just tilt and return to its original position about column.
Don’t put your hands between tyre and clamps, avoiding body injury.
●Move the tire so that the bead passes below the front section of the mounting head is brought up
against the edge of the rear section of the mounting head itself.
●Keep the tire bead pursed down into the wheel rim channel with your hands. Step pedal M to
rotate the turntable clockwise. Continue until you have covered the entire circumference of the wheel
rim.
●Insert the inner tube, if there is one. Repeat the above operation for the other side of bead.
