Is there anybody out there running 20x9 Pro comp 6001 or other wheels with 35x12.50 20 tires and 2.5 inch as leveling kit? Trying to find out if this setup works without a problem. Thanks.

 

That wheel has 4.5" of backspacing.

The 17x9 Pro Comps like what I have have 4.75" of backspacing.

My 35x12.50/17s rub slightly, that extra 1/4" sticking out of those 20s would without a doubt, but the tire into metal.

If I had it to do over again, I would make sure I got a rim with 5" backspacing or better.

 

BLACKOUTFX4 is rocking 325/50r22 with minor rubbing (in reverse) so I think you should be good. But tires that big cost a lot so make sure you get the right ones.
