Get radius of wheel collider in world space?

I want to get wheel collider parameters in world space. I know that WC has method called GetWorldPose(), so I can get position and rotation in world space but I don’t know how to get radius of WC in world space to be able to calculate speed of my WC using rpm and radius in world space. (Sorry for my bad English)

The radius multiplied by the y component by the lossyScale is the radius in world units.
