I am finally ready to buy wheels and tires.. I have a 2.5 in leveling kit, my question is will i be free of any rubbing with a 33/12.5/r18 with -12mm offset and 4.5 inch backspacing?? thanks guys.....looking at the XD spys with toyo open country tires

 

I would think you would be able to do that. i have the same setup only a 9" wheel I think the spys in an 18 are 8.5"...not that it will matter that much. I had to trim just a touch of the front plastic valence. cant even see it. Id give you pic, but i dont have the truck anymore...pics in my gallery.

 

If you have any rubbing, it will be very, very minor.
