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.
BendPak Ranger 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 broken 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 loosened 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 (including Corvette, BMW, and Lamborghini Diablo) have a
pressure sensor strapped to the Wheel
opposite
the Valve Stem. On these Wheels, the Beads should
be loosened at the Valve Stem on both 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, BendPak
Ranger 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.
•
When mounting a Tire
. Put the TPMS sensor just to the left of the Mount/Demount Head.
These are general guidelines; be sure to use common sense and take into consideration the specifics
of each situation. If you still have concerns, speak to your Supervisor.
Important
: When you are finished mounting a Tire with a TPMS sensor, make sure it is working. It
is against the law to
knowingly not
re-install a working TPMS if the Vehicle arrived at
the facility with a functioning TPMS. If a Vehicle came in with a functioning TPMS, it
needs to leave with a functioning TPMS.
