If you are Breaking the Beads of a Tire with a TPMS, put the sensor at 12 o’clock high or 6 o’clock
low (relative to the ground), to reduce the chances of damaging it.
9.
Move the Blade so that it is on the side of the Tire, very close to,
but not touching
, the Rim.
⚠
CAUTION
Make sure the Blade is
not
touching the Rim. The Bead Breaker Mechanism uses
a great deal of force; you will damage the Rim if the Blade pushes on it instead of
on the side of the Tire.
10.
Step on and hold down the Bead Breaker Foot Pedal.
The Blade moves in, moving the Bead out of the Bead Seat and in towards the Tire’s Drop Center.
When the Bead breaks, it frequently (but not always) makes an audible popping sound.
11.
Release the Bead Breaker Foot Pedal when the Blade goes all the way in or the Bead is broken.
12.
If the Blade does not fully move the Bead out of the Bead Seat, adjust the Blade a little bit one way
or the other and then repeat Steps 10 and 11.
It may take several attempts to break the Bead.
13.
When the Bead is broken at the first spot, rotate the Tire 180° and break the Bead at that location.
Every Tire is different. With some Tires, the entire Bead on one side could be broken with the first
use of the Bead Breaker Blade. Other Tires could take multiple attempts until the Bead is broken all
of the way around the Tire.
14.
When the Bead is completely broken all the way around on one side of the Tire, move the Tire out,
turn it around, and then break the Bead on the other side of the Tire.
Again, avoid breaking the Bead at the TPMS; you could damage the sensor.
Important
: It may take you two or three times to break the Bead at any one spot. Nevertheless,
keep going until you break the Bead all the way around the Tire and on both sides
of the Tire.
Do not proceed to demounting the Tire until the Bead is
broken all the way around and on both sides of the Tire
.
