14.
Take the Bead Lifting Tool, put it on the outside of the Demount Lip, then slide it down past and
under the bottom Bead.
Getting the Bead Lifting Tool into position may be trickier this time, as the rest of the Tire is in the
way as you are trying to get access to the bottom Bead.
-
Tires not shown for clarity. Side view. Not necessarily to scale.
15.
Push the Bead Lifting Tool towards the middle of the Wheel in an arc, pulling the bottom Bead over
the Demount Lip of the Mount/Demount Head.
16.
While continuing to hold the Bead Lifting Tool, press down on the Turntable Foot Pedal to move
the Turntable clockwise.
Watch the bottom Bead to make sure it is being pushed over the top of the Rim as the Turntable
moves.
17.
Keep turning the Turntable until the entire bottom Bead pops over the top Rim.
The Tire is now dismounted and can be removed.
Wheel / Tire Mismatches
A Wheel / Tire mismatch is mounting a Tire where the Tire’s Bead diameter does not exactly match the
Diameter of the Wheel.
⚠
DANGER
A Wheel / Tire mismatch is extremely dangerous
. A mismatched Tire and
Wheel may separate or explode, resulting in injury or even death.
The differences can be subtle, so you must take care to get an
exact match
.
For example, a 16 inch Tire goes on a 16 inch Wheel, not a 15.5 or a 16.5 inch Wheel. It may be
possible to slide the 16 inch Tire over the Rim Lip of a 16.5 inch Wheel, but during inflation it will
not
seat properly.
⚠
WARNING
Do not
mount a Tire on a Wheel until you,
yourself
, have positively identified and
correctly matched the Tire and Rim diameters. If you try to seat a Tire Bead on a
mismatched Wheel and Tire by inflating it, the Tire Bead may break with explosive
force, which could result in serious injury or death.
