Rack your brains.
 

Question guys just swapped wheels back to 18" from 17" oem on my newage. I was reading a while back that you cant mix different wheel sizes on 4wd cars with front and rear diffs as its not good for them. Eg 17s on the front and 18s on the rear. As most of us are running 18s on the newage how do we stand using the standard spacesaver then because im guessing this is to be used with 17" wheels as its from factory. Is it a no no even for short trips to the tyre centres.

No you will damage the centre diff , you need to fit the same size front and rear

Yes thats what i was thinking. Thanks for the reply
