7.5 REMOVING A TIRE THAT HAS A SMARTIRE
™
SENSOR INSTALLED
This section outlines the correct methods for removing a tire from a wheel that is equipped with a
SmarTire
™
sensor. Instructions for using both tire irons and a tire mounting machine are provided.
Please read these instructions carefully and follow each step precisely to ensure you do
not damage a sensor when dismounting the tire. If steps are not taken to avoid the sensor
located in the drop center well of the rim, it can be crushed by the beads as the tire is
removed.
7.5.1 Using Tire Irons
1. After removing the deflated tire / wheel
assembly from the vehicle, lay the assembly
on a floor mat and unseat both beads
directly opposite the sensor. The sensor
should be located at the valve stem (the rim
mounted decal should also indicate the
sensor’s location). Do not unseat the bead
at or near the sensor / valve stem.
2. Ensure that the mounting side of the wheel
is facing upward and both the bead and
wheel flange are properly lubricated.
3. Starting near the sensor, lift the top bead
over the wheel flange using tire irons and progressively work away from the sensor until
the top bead is free. Be careful not to contact the sensor with the tire irons.
4. Again starting near the sensor, repeat the process for the bottom bead until the tire is free
from the wheel.
7.5.2 Using a Tire Mounting Machine
1. After removing the deflated tire / wheel assembly from the vehicle, unseat the beads
directly opposite the sensor and valve stem. The sensor should be located at the valve
stem (the rim mounted decal should also indicate the sensor’s location). Do not break the
bead at or near the sensor / valve stem.
2. Position the lubricated tire / wheel assembly on the machine so that the dismount head
and the sensor are approximately aligned.
3. Lift the bead over the rim flange with the bead lifting bar and then advance the assembly /
dismount head clockwise to remove the top bead.
4. Repeat steps 2 and 3 to remove the bottom bead.
NOTE: This information should be provided to tire installers that are not authorized
SmarTire
™
TPMS dealers to ensure a sensor is not broken when a tire is dismounted.
