Wheelcollider help

I am currently using a car for a car racing game im making, which does not have its wheel and main body axes aligned properly. for example for each wheel the x axis is forward ,y axis is up the z axis is to the left. Now when I apply motortorque to the wheelcolliders attached to the tyres, the wheels do not move forward but rotate sideways.Is the motortorque rotation calculated around x axis in unity engine by default just like steer is around y axis by default?
Is there any way to get around this??

Thanks

Creat an empty GameObject for each tire, drag and drop tire into GameObject and then apply wheel collider.
The Forward Axis for wheel colliders must be the ZAXIS.
By using GameObject, you will have proper Orientation of your wheels within the GameObject.
