Couple of questions;

1. If i use SetObjectRotation() then RotateObjectLocal[X/Y/Z]() do not work
2. If i use RotateObjectLocalY() and then RotateObjectZ() i expect it to act like the wheel of a car and rotate around the axle but it tumbles end on end

Am i doing something wrong or are they the expected results?

don't really use 3D myself but perhaps try FixObjectPivot in between the local and the global rotations.

if it is for a racing game i would split into damper axis and wheel.
so the wheel can turn relative around x and the damper is absolute the steering y axis.
the car drive local z axis forward.

It isn't related to physics. I am just trying to rotate the wheel around the y axis and then around the z axis (locally)
@smallg : The pivot is already in the center of the wheel
@markus: Are you suggesting i have two objects? one for y rotation and one for Z rotation? It might be a problem because the wheel is already fixed to the body. I'll check if i can fix objects to objects within objects

i think your problem belongs the rotation order of each axis.
if you try always a relative rotation locally for the wheel i guess it will work but it will be inaccurate after a while for the steering angle.
yes, i would try split into a hirachie.

Yes, thanks markus.
I added a small plane, attached the wheel to it and used it as the Y axis then rotated the wheel along the Z axis
