7.4 RE-MOUNTING TIRES AFTER A SENSOR HAS BEEN INSTALLED
Please read this section carefully and follow each step precisely to ensure you do not damage the
sensor when mounting the tire. If steps are not taken to avoid the sensor located in the drop
center well of the rim, it can be damaged by tire beads as the tire is mounted.
7.4.1 Internal Tire Sensor Servicing
SmarTire
™
tire sensors are designed to be serviceable if damage occurs during the mounting or
de-mounting process. Each sensor is mounted inside a break-away cradle that is designed to
absorb the impact of damage during the tire mounting / de-mounting process. If damage occurs,
the inexpensive cradle will break instead of the tire sensor.
If a sensor cradle is damaged, it along with the mounting strap must be replaced. Carefully
remove the tire sensor from the damaged cradle, re-insert it into a new cradle, and then continue
the mounting process.
7.4.2 Re-Mounting Tires Using Tire Irons
To avoid damaging the sensor, simply mount the tire so that the last part of the bead to slip over
the flange happens directly at the sensor. Start at one end of the tire and work towards the
opposite end with the tire oriented so that the beads are first pushed under the rim flange directly
opposite the sensor (1) and then worked over the flange toward the sensor (2). The bead will
finally slip over the rim flange at the sensor without contacting it (3). Repeat for the remaining
bead.
7.4.3 Re-Mounting Commercial Tires Using a Vertical Tire Machine
1. Place the rim on the machine so that the rim flange clamp is at the 12 o’clock position,
the sensor is at the 2 o’clock position and the mounting hook is at the 8 o’clock position.
