[Closed] Modifier gizmo rotation?

I created a simpleMod modifier that squash the tire of a vehicle. I have the modifier working great but as the tire rotates so does the modifier. I have linked the tire geometry to a dummy and that is whats driving the rotation of the tire. I decided to write a rotation_Script controller for the modifiers gizmo, what I want is for the gizmo to only follow rotations in the local x and z axis of the dummy object and ignore the rotations in y that way the deformed part of the tire is always facing the ground. I not very good with working with transform matrices and rotations in general. In suggestions on how to do this would be great.
