What offset/ backspacing on a 10" rim?

Hi guys

I tried searching but couldnt find the answer im looking for........ so here goes.

I recently bought a 89 F150 4x4 and plan to fit 33x12.5 R15 muds on it.
Im after what offset / backspacing i should go for on a 10 inch wide rim?

Can people tell me what they are running or better yet post some pics so i can see how far the tires stick out past the guards.

I want to make sure i get the look right

Cheers
Jordan

Stock wheel has 4.5" backspacing and that puts the wheels in under the fender, but then the wheels are only 7" wide. I had 8" rims with the same backspacing and they were about flush with the outside of the fenders.. looked much better IMO. A 10" rim will definitely stick outside the wheel well and 33" will rub the bumper and radius arms no matter what offset you use.

I was thinking either 3.75 or 4 inch backspacing ...... need to see what it looks like though.

I'm running a set of Eagle Alloy Series 058's, 15x10" with 3.625" backspacing. I've run two different sets of 33x12.50-15's on them now. With about 2" of lift, they do NOT rub on the radius arms...or anything at all for that matter.
