Sorry Guys/Gals...Another wheel backspacing question

I have a stock suspension with stock canyon wheels. I'm running 31 x 10.5 A/T tires. I'm wanting to get new, black cragar's but I want to give the jeep a little wider looking stance, but not look ridiculous. I understand that the canyon wheels have 5.5" of backspacing. What backspacing should I look at to push the tires outside the fender flares just a little bit? 5", 4.75", 4.5"?????

At some point during jeep ownership, you will BUST A NUT!!!

What backspacing you choose/require depends on the biggest tire you'll ever place on them. And how much further out they stick out is entirely dependent on the backspace dimension itself.

Assume a 15x8" wheel:

The factory wheel has 5.5" of backspacing and I will assume it is a 15x8.

A 15x8 wheel with 5" of backpacing will protrude out of the wheel well 1/2" more... 5.5" - 5" = 1/2" more out of the wheel well.

A 15x8 wheel with 4.5" of backspacing will protrude 1" more... 5.5" -4.5" = 1" more.

If your OE wheels are only 7" wide, then the outside edge of any 15x8 wheel will protrude 1" further out if both wheels have the same backspacing. So if your OE wheels were 15x7 and had 5.5" (typical) backspacing, an aftermarket 15x8 wheel with 4.5" of backspacing will protrude 2" more.

Backspacing wise, 5" of BS will handle tires up to 11.5" of width. 4.5" of BS will barely kinda sorta handle 12.5" tires but 4" is better if you don't want to have to adjust the steering stop bolts to slightly restrict how far the wheels can be turned to prevent inside sidewall rubbing on the control arms.

Make sense?

When you have a choice, buy American.

Thanks Jerry...I sounded kinda dumb asking the original question since I kinda knew that if I had 5.5" of backspacing, and went with a 4.5" backspaced wheel, I'd have a 1" wider stance.
I run 31 x 10.5 wide tires that are in great shape, and don't plan to lift the jeep.
I want to give the jeep a wider looking stance and am thinking about getting some inexpensive black steel wheels.
The tires are currently just about flush with the fender flares....if they are sticking out an additional 1", would it make it look stupid?
Does anyone have pics with a similar set up to what I'm talking about?
