DT-50 and DT-50A Tire Changer
35
P/N 5900260 — Rev. A1 — Dec. 2020
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, talk with your Supervisor
before
starting work.
Working with Custom and Special Wheels
This section covers working with Alloy Wheels with no drop center, European performance Wheels,
and Wheels with Tire pressure monitoring systems.
Alloy Wheels
Some manufacturers offer Wheels with little or no drop center. These types of Wheels are almost never
Department of Transportation approved.
⚠
DANGER
The Tire, Wheel, or both can be damaged and the Tire could explode under
pressure, resulting in serious injury or death.
Dannmar recommends you not
try to demount or mount this type of Wheel
. If you do attempt to demount
or mount this type of Wheel,
proceed with extreme caution
.
European Performance Wheels
Some European performance Wheels have very large humps except near the Valve Hole.
On these Wheels, the Beads should be loosened at the Valve Hole on both the upper and lower sides
first.
Wheels with Tire Pressure Monitoring Systems (TPMS)
Some Wheels have a pressure sensor located behind the Valve Stem. On these Wheels, the Beads
should be broken opposite the Valve Stem on both upper and lower sides first, before breaking the
Beads on the rest of the Tire.
Performance Wheels on some Vehicles have a pressure sensor strapped to the Rim opposite the Valve
Hole. On these Wheels, the Beads should be loosened at the Valve Hole on both the upper and lower
sides first, before breaking the Beads on the rest of the Tire.
Be mindful of the TPMS sensor when breaking a Tire’s Bead, demounting a Tire, and mounting a new
Tire. If your shop does not have specific recommendations for handling these situations, Dannmar
recommends:
•
When breaking a Tire’s Bead
. Keep the TPMS sensor away from where the Bead is being
broken. Put the sensor at 12 o’clock high (relative to the ground) when breaking the Bead.
•
When demounting a Tire
. Put the TPMS sensor just to the
right
of the Mount/Demount
Head.
