Demount the Tire
Demounting a Tire is the process of taking a Tire off a Wheel. Specifically, you need to pull the top
Bead over the
top
of the Rim, then pull the bottom Bead also over the
top
of the Rim.
⚠
CAUTION
You
must
use Tire lubricant; this makes the Tire demount more easily and helps to
prevent damage to the Wheel and/or the Tire.
During demounting, the Bead goes over the Demount Lip of the Mount/Demount Head but stays
⚠
WARNING
The following procedure
requires
that the Tire’s Beads are broken on
both
sides.
Do not
try to demount a Tire whose Beads are not broken on both sides; you
could damage the Wheel, the Tire, or even injure yourself or bystanders.
To demount a Tire
:
1.
Make sure you are wearing OSHA-approved (publication 3151) personal protective equipment:
leather gloves, steel-toed work boots, back belts, hearing protection, and ANSI-approved eye
protection (safety glasses, face shield, or goggles).
2.
Verify that the Tire’s Beads are completely broken on both sides of the Tire.
3.
Apply Tire lubricant to both the top and bottom Tire Beads and the top and bottom Rim.
This helps slide the Beads over the Rims more easily.
4.
Move the Mount/Demount Head into position, very close to the Rim
but not touching it
, and
lock it in position using the Shaft Lock Handle.
Tip
If you are working on multiple Wheels of exactly the same size, you can “lock” the
Mount/Demount Head to this location using the Swing Control, located next to the
Swing Arm at the top of the Tire Changer. Refer to
At this point, the top Bead is under both the Mount Lip and the Demount Lip; it needs to be
brought up over the top of the Demount Lip.
5.
Push the top Bead 180° opposite the Mount/Demount Head into the Drop Center of the Wheel.
This gives you some extra room to help pull the top Bead over the Demount Lip.
