Steering wheel bug. (Oculus VR Controls)

Issue: Steering wheel will rotate on the Y-axis instead of the z-axis unless you remove other.tag == "GameController" from the if statement.
But if I do that, then the player can still control the steering wheel without touching the wheel because it is constantly colliding with the car.

Please help me.

17.         float rightSquez = OVRInput.Get(OVRInput.Axis1D.SecondaryHandTrigger);

19.         if (other.attachedRigidbody && other.tag == "GameController") //issue == can steer wheel when not touching wheel if hands are squeezed
