Before You Change a Tire
⚠
DANGER Do not use the Tire Changer unless you have been properly trained and have read
the entire
Installation and Operation Manual . Tire changing must only be done by
trained, authorized, supervised personnel.
Failure to understand and follow
proper procedures will result in injury or death .
Before you change a Tire, you should:
•
Remove weights . Check the Wheel to make sure that all clip-on and adhesive weights (from
having the Tire balanced) have been removed.
• Deflate the Tire . This is required. You must fully deflate Tires before demounting
them .
To make sure a Tire is fully deflated , remove the Valve Core from the Valve Stem. You should use a
Valve Core Tool for this, but if you do not have one, you may be able to use needle-nosed pliers.
• Have Tire lubricant ready . Tire Lubricant makes the process of demounting and mounting
Tires much easier. If you do not use Tire Lubricant, you significantly increase the chances of
damaging the Wheel and the Tire. Tire Lubricant is not provided with the Tire Changer.
• Check for damage . Especially with expensive Wheels, make sure to check them for any
damage before changing the Tire. Depending on the circumstances, if you find any damage you
might want to discuss that damage with the owner of the Vehicle and/or photograph the damage.
If you work in a shop, talk to your supervisor regarding shop policies in this area.
Additionally, damaged Wheels and Tires are dangerous to work with. If you are not sure whether a
Wheel or Tire is too damaged to work with, talk to your supervisor.
• Understand Performance Wheels . Before servicing performance Wheels, review the
Performance Wheels section of this manual.
• Identify the Narrow Side/Drop Center of the Wheel . The rule is: the Narrow Side/Drop
Center side of the Wheel gets put onto the Tire Changer facing up. For most Wheels, this means
the side of the Wheel facing the
outside of the Vehicle goes on top, because that’s where the
Narrow Side/Drop Center side is on most (but not all) Wheels.
The following drawing shows two Wheels and identifies the Narrow Side, Drop Center, and Wide
Side of each.
Some aftermarket and OEM performance Wheels are
reverse
drop-center Wheels, meaning the
Narrow Side/Drop Center side of the Wheel is closer to the inside of the Vehicle. The rule still holds
for these Vehicles: the Narrow Side/Drop Center side of the Wheel gets put onto the Tire Changer
facing up.
• Ask your Supervisor . If you have
any
concerns about a Tire you have been asked to demount
or mount, or about how to use the Tire Changer, consult with your Supervisor
before
starting
work.
