Ok heres my situation I want to come true hopefully.

I'm going to get my T-bars cranked to level out the truck so I fit 285/70/17
I want to get the BFG KM2 in that size also would it be possible to get wheel spacers so I can widen all 4 tires a tad bit. not to far out, but just enough. you know what I mean? is that possible?

 

It's possible, but I wouldn't do it. You will be better off to put that money toward a set of wider aftermarket wheels in my opinion.
