I have a 2010 ranger fx4. It is getting the superlift 4" kit. I would like to put a set of 33x10.5x16's under it, or a close (slightly bigger) metric equivalent. I'm trying to figure out how much backspace on the rim. And still have the tire tuck into rear wheel wells when articulating the suspension. I have those cheesy stock fender flares I am willing to trim, as they overhang inside the wheel well s in the rear. I'm not even sure what the stock backspace is to start with. Any advice or knowledge would be appreciated

 

I think stock back spacing is 4"

 

Stock is 4.5"
