backspacing

[G-Force8]

I'm looking at picking up a set of wheels for the 3/4-ton swap on my burb. I know jack about back-spacing. How much is ideal and how much is too much?

the truck is a '91 1500 suburban. The 10-bolts are taking a ride in favor of a Dana44HD/14BFF.

There is a set of wheels locally I'm considering that have 4-3/4" of backspacing. Is that going to tuck the tires in to far? I'll be running 35x12.50R16.5" tires

not 100%, but i think stock is round 4"...guess it depends which way the offset is...

I'm running 36x13.50/17's on 17x9 with 5" backspacing (8 lug). I like it, because the tires are pretty well tucked under the body. It seems like a lot of 16.5 rim are 9.75 wide, but 4 3/4" bs would be fine. It won't have the tire rubbing the frame or anything like that, since mine don't.

Hmm,sounds like 3.5" may be more what I'm looking for then. I like the tires to stick out a little bit past the fenders. Or, I could use wheel spacers until I get the ones I want

Any way you can post pics of yours so I can get a look at it?

Another guy offered up a set of 16.5x10 Eagle 589's with 5" of backspacing. like the look and want to see how they tuck in

I suppose I could. The 16.5x10's will stick out an inch farther than mine, since they're wider and have the same backspacing. Will these pics do? I don't like to post pics of my truck unless it's doing something.

sweet. Good looking truck. Glad you've kept the stock grille instead of going with a billet. The '73-75 chevy and gmc grilles rock.

That backspacing looks fine to me. I'll be starting out with a 12.50 tire, then a 15.50 when they wear down.

Thanks, and good luck with your truck. I'm not really the billet and chrome type. I'm more proud of my dents and broken parts.

My wheels are 5" backspacing on a 16x8 wheel and they fit great over the 3/4 ton axles with no rubbing.
