I am planning on getting new wheels and tires for my new CC next week. I have already picked out an 18" wheel that I like. It has 4.5" of back spacing. I had planned on going with the 285x60x18 (31.38x11.54x18) Nitto Terra Grapplers. I have had them in the past and really like them. I recently started thinking about going to the next size up, which are 325x60x18 (32.99x12.83x18). I like the looks of the 33"tires better but havent decided if I want to reduce my fuel milage even more. My question is, if I decide to go with the bigger tire and I crank up the torsion bars until the truck is level, will I have any problems ? I dont want to have any rubbing issues or have to trim anything on my new truck. If thats the case I will go with the smaller one for sure.
