ok i did the search thing for the last hour but i am tooo hung over and couldn't find the answer. i know if i go 15 inch rims i gotta go with either 3.5 or 3.25 inches of backspacing which seems to be hard to as i am searching right now. i though i heard before on here if i go up to 16 inch rims i don't have to worry bout backspacing as then it won't hit the tie rod ends. is this correct? cause 4 inches of backspacing seems to be pretty common. also i have a 4 inch lift and i am gonna go with 33 inch tsl's with a 10 inch wide rim.
