Ok so i am pretty new to the tire and rim thing, but currently what i have is a 2006, F150 Screw, 2wd, i am about to invest in a 3 inch rough country leveling kit, and i am about to buy kmc xd 778 (monsters) 18 by 9 and some nitto terra grapplers, So i was wondering what is the biggest tire size i could get without rubbing and it sticking out a little bit from the truck. I was thinking 305/70/18 load XL, perhaps another size or do you think this tires will not look good with them only equalling up to 32.4 inches ( Ibelieve i might be wrong) Suggestions? And i want to make my truck as tall as possible without a suspension lift or a body lift, sosuggestions on that too? I read you could get a 1 1/2 block in back with longer u bolts and 3 inch in front and it would look better, yes no?
