I have a 2007 Sahara Unlimited. I am setting it up with a 3inch lift and 33X12.50R17 inch tires. The rims are 8 inches wide with 4.75 backspacing. I know thay the added weight from the bumpers and winch will bring it back down up to an inch potentially. With the added lift would I need to worry about the 33's rubbing at all. I know they are not huge, but would like to avoid any issues. Ergo....do I need some wheel spacers?
