System Structure: Wheels
The TPMS will not work unless TPMS type wheels are installed on the vehicle. There are four different types of wheels used.
- Type 1 (aluminum wheel) and type 2 (aluminum wheel): The original equipment wheels have a "TPMS" mark (A) on them. The wheels also have counterweights (B) incorporated on the opposite side of the tire pressure sensor (C), to counterbalance the weight of the sensor.
- Type 3 (aluminum wheel): The original equipment wheels have a "TPMS" mark (A) on them, and a counterweight (B) are mounted by removing material around the valve hole to counterbalance the weight of the tire pressure sensor (C).
- Type 4 (steel wheel): The original equipment wheels have a "TPMS" mark (A) on them, and a counterweights (B) balances the weight of the tire pressure sensor (C) by a size difference in the wheel disc holes.
