Backspacing?

I want to upsize to an 18 0r 20 in wheel on my truck. I'll be running a 37-12.50 or 13.00 on them. So Im wondering what sort of Backspacing should I have (4.5", 5.0" or )
Not to make myself sound dumb (too late) But I just dont want anything to rub.

Thanks,

JB

Measure from the base of the lugs to the nearest obstruction. Remove 3/4'' and that's your max backspacing.

4-1/2" backspacing with a 9" or 10" wide rim should be just right.

Only on a 2005 or newer would you want 5-1/2" or 5-3/4".
