Too much backspacing?

Long time stalker of this forum. Great resource!

I'm in the market for some aftermarket wheels/tires and based on the info I have gained on this forum, the sweet spot for wheel fitment is 4.5" of backspacing. I'm looking at these Moto Metal MO970s and plan to run a 285 wide tire. These only come in a 5.7" backspacing. Is this too much backspacing where I could have issues with the tire rubbing on the UCA?

Try this out to get an idea.

 

Thanks HEGR! That is a clever tool. So, based on the results of this tool, comparing stock wheel/tire combo to the aftermarket combo, this places the inside of the wheel/tire about an inch closer to the suspension.

So, even with aftermarket UCAs, I'm thinking this still places the tire too close that rubbing would occur. Guess I need to find another wheel with the magical 4.5" backspacing or run wheel spacers !
