What's the most backspacing you've seen?

[Marlin]

I would try talking to marlin or littlebeast. Iirc they bothe have larger width rims with close to a factory offset, so that should at least be a little more backspacing than factory.

Yep, you got it. I got as close to factory offset as I could.
Here is where I started, and since then, I have kept the same wheels as shown here, but went up to a 34"x11.5" tire. I also lowered the front end down to almost stock height, looks funny, but improved the offroad handling drastically. My VX just sits in the driveway most of the time, less than a tank a gas through it a month.

Thanks guys.

One thing that confuses me is the stock wheel is listed with 38mm offset. Since it's a 7" wheel, the center point would be 3.5". 38mm is right at 1.5".

1.5" + 3.5" = 5" backspacking for the OEM wheel. (According to my calculations).

But this chart shows it should be 5.5" backspacing. The chart looks wrong.

Or I don't understand something.



(I also did a search on backspacing. I looked thru most of the threads with that term. Not a single post mentioned OEM backspacing. Since my new VX no longer has stock wheels, I cannot verify what it SHOULD be.)

If it's of any help, my Centerlines have 5" of backspacing on an 8" wide wheel.

Here's my real questions:

1) Would a 20x9" dub with 10mm offset stick out 2" further than stock?

2) Would the same wheel with 30mm offset have too much backspacing?

10 and 30mm are the two choices for offset in a wheel I like

1) That's what I get (well 2.1" and change)

2) If I understand the equations correctly, I think that 30mm offset would generate too much backspacing.

JUST DO IT! Patience and thoughtfulness != timely mods.

Ughhh....what's this forum category for? Since it included a GIANT wheel thread, I thought it was the correct location. Is it not?

Wanna let me in on the joke?

Well let me add another then...

[89Vette]

OK., thanks.

Without a specific reply, let me try the question this way....

Is anyone running wheels that have 3/4" more backspacing than stock? Basically, I'm trying to figure out if up to 1" more backspacing (than stock) will fit in the wheels w/o rubbing. For sake of argument, lets say it's with 30" diameter tires.

Marlin, you still look way above stock height. With a 31" wheel, mine is sitting WAY further up into the wheel well -- on the front. Mine is further up than your pic on the ramps!

With 12mm offset and 2" more wheel, I gotta assume your tire is sitting more outboard that the two pics in this thread portray.

Hold on, read the post, I am at stock height now, or very close to it anyway.
The tires in the pics were only 32" x10.9". Those pics are from 2 years ago when I first lifted the truck and a bunch of other hoohah..

As for the offset and whatnot, this info is straight off the shipping bill for the wheels:

Here is what the truck looks like now:

The tires do stick outside the cladding an inch or so. Not enough to look silly(for you Tom), but enough give it that wider more aggressive stance.

Yes, you can adjust the steering stops to minimize rubbing. Page 2A-16 in the shop manual. Fairly easy to do. So even if you do get rubbing, you can just set the stops to make it go away.

I"m running a backspacing of -6 on a wheel that's 18x8.5 at stock height and I love the look...had to do some minor cladding trim front and rear, but no rubbing issues lock to lock and I have about 1" of tire outside the edge of the cladding.

Your truck looks good! With that little trimming, you are gonna rub if you go wheeling, especially on steep descents. The wheel does move around a bit from front to rear. But I would guess by the pics, your truck is not a wheeling kind of truck

My tires do not stick out quite as far as yours, but pretty close.
