I have two trucks that are getting leveled and new wheels and tires, one is a 2005 stx (4x4) and the other is a 2010 fx4 (4x4). I was planning on using the rough country 2.5 inch leveling kit with the rear block lifters as well (featured in link below). Rough Country recommends 35s, however id like more opinions. I would like to put 35s on them but I'm concerned of rubbing, i don't want to have to trim anything. I realize it mostly comes down to backspacing of the wheels. both trucks have been running the 20 inch lariat wheels. Does anybody know the backspacing of those wheels and or what backspacing will be needed to fit 35s on that leveling kit? Any help would be great

 

I believe stock backspacing is 5.71...stay around there and don't go over 12.50 wide and you should be golden

 

thank you for the insight... would less backspacing make it less likely to rub??

 

depends on how wide the wheel is and what you decide for an off set...normally 4.5-5.5 backspacing is good
