20x8.5 +45 frnt and 20x9.5 +45 will work... just got to roll fenders.. you cant get the max lip with that!
The rears if you do your homework can fit 10's without rubbing..
What kinda of offest would you need to run a 10" wide rim? I don't want 20's but I been thinking of 18's that are 10" wide in the rear.
