Backspacing

Can you buy 16" wheels with close to hummer backspacing?

You know hummer wheels have like 9" of backspacing right?? Why would you want that, you will rub nearly everything... I had my hummer wheels recentered to 4" of backspacing

You don't mention what bolt pattern you need, but American Racing makes the 767-6882, 5.15" bore, 12mm offset, 5" BS, 16x8, 8x6.5

I used to own a 1995 Tahoe, and recall the stock steel wheels were 6.5" wide with a 4 3/4" backspacing? I think the aluminum ones are 7" wide with the same BS...

BTW, I think H1 wheels are 9.5" wide with a 7" backspace.

I am using full width axles (chevy 14 bolt) on a buggy that will be narrower than say a stock Jeep, so width isn't and issue as far as rubbing. I was hoping that the axles wouldn't be too wide, so I was thinking of using wheels that are more centered.

Does a higer backspacing number = less off centered?

You might still have an issue with rubbing on leaf springs and steering arms.

An 8" rim is going to measure 9" wide. If the backspacing is 4.5" then it will be centered. If the backspacing is 7", then it will be moved inboard 2.5" and your rig will be narrower. At this point you have to worry about front hubs being exposed to rock damage.

So say you get a 10" rim which measures 11" wide. Its center is at 5.5" so that same 4.5" backspace will put the tire 1" outboard making it wider.

Makes sense and thanks

Pretty sure my 8 bolts are 8.25" wide with a little over 7" b/s... But I would have to check to make sure...

You are correct. They are 8.25" wheels, which is how much space is available for the tire (inside measurement). But if you check the outside measurement, you will find its about 9.25" wide.

Now, if you talk about offset, which is measured from the wheel centerline it doesn't matter. But if you talk backspace, it seems to be measured from the outside of the wheel.

Please correct me if I'm wrong, this backspace/offset stuff makes my head hurt. I'm just telling you what I've figured out after spending too much time with a tape measure...
