Please post pics of wheek setups with different backspacing. Preferably something that sticks out FAR past the fenders.

 

pretty sure you are limited to perhaps 5" of backspacing no matter what size width tire you run.

factory is 3.5...most say 4.5 is suggested but I find thats a pretty rare backspacing with 4.75 and 5 being FAR more common in selecting aftermarket rims.

12" rims with 4-5" backspacing will stick out FAR from the fender...sounds like thats what yer lookin for.

mine is 10" with 4.75 of BS and it sticks out perhaps an inch or two, but nothing dramatic.

 

Most jeep guys run 15x8 or 10 with 3.75 bs. I got 15x8 with 2.5 bs and they stick out far

 

guess youd have to define "far" then =)

factory rim is 16x7 with 3.5 of bs

cant imagine a 15x8 and 2.5 bs would stick out THAT far...maybe what, 2" over stock.


that said, you could be putting a really bulgy tire on it with a substantial sidewall that would add to that look.

 

i guess im trying to get an idea of which wheels i want.

heres an example of a rim (this happens to be 10" wide) with 2.5" BS.

the reason those stick out that much further is that they essentially put ford solid axles under a jeep wrangler =)

heck on that jeep the axles are so much wider than the jeep even the hub is sitting outside of the body.

I dont believe you are going to accomplish this look on an excursion without a seriously skeptical setup...ie some thick spacers...and 12-14" rims with a very small backspace.

 

What would be the absolute lowest offset I could get, and I plan on getting like 20x14s also.

 

offset and backspacing are two different things.

offset is the distance the "hub" on the rim is off from the dead centerline of the rim itself. (ie forward or backwards)

backspacing is the distance the hub is from the back of the rim.

while im sure they do make rims with super small backspacing, i would be weary of the load limits on them for such a large truck as so much of the weight would be cantilevered outside the hub.

 

this would show you an example of a rim with very small backspacing (although its hard to tell how much from this picture, but you can see the mounting hub and spokes are way back in the rim...with a large lip protruding out. thus causing more of the rim and tire to stick out past the fender of a stock vehicle.

 

I think that might be backwards.

I am looking at some 20x12s for my excursion and most of them are -44 offset with 4.5 to 4.77 backspacing.

Those rims look like this



Those are 4.77^^^

 

thats still correct...its (being where the wheel mounts to the hub on your truck) 4.75" from the back side of the rim.

-44 is 44mm negative offset...ie how far it (same as above) is off from the centerline of the rim itself.

44mm is roughly 2 inches...so if the rim is 12" wide...the inner rim/spokes/etc sit 2 inches back of dead centerline in the rim...thus giving you 4" of backspacing.

(note that if that rim had 0 offset, it would have 6" of backspacing)

 

I actually have very similar rims as the ones you are looking at...mine are 20x10 with 4.75 backspacing...which is essentially 0 offset (or .25" of negative offset)

they dont stick out much at all with 35s mounted
