Backspacing question for 20 inch wheels

How do i find out back spacing? Looking at a set of ultra 20's all i can find is the offset is 14mm?? I have a 2003 f250 will these work? 33x12.5 tires with a leveling kit

+14 offset should set about even with the fender. My wheels are 20x9 with +10 offset and they set even. But if the ones you're looking at are 10" wide, they'll probably stick out a little farther.

If the backspacing is 4.5" and your tires are 33x12.50, with a leveling kit you shouldn't have any problems.

I have the same back spacing with 35's...I had to do minor cutting on the bumper and inside well...you'll be fine
