Found Offroad Rims That Have our Lug Pattern!!!

James is the person to ask but IIRC he said that the back spacing would need to be 6" without spacers.

It's all simple addition and subtraction.

Measure your current distance to the ball joint. We will call this X.

Now, figure out what the difference is between your current backspacing (including wheel spacers) and the new rims. If you currently have 4" and the new ones have 5", you will have to subtract 1" from X. This will be called Y.

Now, figure the difference between your tire widths. This is based solely off the first number of the tire spec. Say you have 265 now, and want to go to 305. That's a 40mm difference, which means 20mm per side. 20mm = 0.78in. So subtract 0.78 from Y.

As long as Y is positive, your tire should clear the ball joint.

You guys need to read the stickie. 6" is stock rim backspacing. In order to fit most larger tires (up to maybe 285 width) you'd need backspacing of 5" or less.

James may not be the person to ask a simple question.

I teach you to fish rather than hand you a salmon.

I teach you to fish rather than hand you a salmon.

If you take the sidewall times the inverted pyramid of X you should get the throttle of Y and thus the proper frontspacing.

Yes and we appreciate that fact but the idea of floating around with the poo on the OS to most likely find mis-information is a large waste of my time. Let this most wonderful site be the 'For the Record' setter.

Oh crap I just saw the 'stickie' you meant. I think I'll only speak on things I know.

James teaches you how to fish using a stick and some line and a hook...


I give you a rod, lures, and a fishfinder:

Use this calculator and just plug in all the numbers to see what the difference is!

[foosh]

Oh, but grasshopper, the fish you want is not obtained by fancy new techniques. You can go out in a battlewagon and come back with less then what I got in my row boat. Ever read the old man and the sea?

[Philberto]

If I remember correctly, he spent all that time and effort with the old method, and came home with nothing

-edit: Well, he came home with a mostly-eaten fish, which was useless anyways.

[foosh]

That may be true but when I take the row boat out, I get that fish in the cooler! Anyways I'll figure out the fitmint issue a little later.

So is this wheel offered with the back spacing needed from Pro Comp?

I know a couple of you guys know about these, but i wanted to post this up for everyone else.

They have them in 16 x8 and 16 x10 with 4.5 backspacing.

Is this wheel the perfect fit?

[Philberto]

Yeah, basically.

[bgwolfpack]

Wow, that took long enough.

[Trail X]

Keep in mind, the 4.5" backspacing means you have the same backspacing as a stock wheel with a 1.5" wheel spacer.

However, it's a 8" rim, vs. a 7" rim (stock). So your outer tire face will stick out up to an inch further when on the 8" rim. Not a big deal. Just potentially means more trimming.

[foosh]

Thats why i'm thinking a 10 inch wide Rim would be better it would be 2 inches wider on the outside but would be further away from the BJ.

[bgwolfpack]

James is the person to ask but IIRC he said that the back spacing would need to be 4.5" without spacers for an 8" wheel.

[Trail X]

Backspacing is a measurement independent of the rim width.

You should only go up in rim width if you have to based on the tire specifications. A wider tire thread requires a wider rim. So if you want a 315 width tire, you may have to get a 10 inch rim.

[foosh]

I know a 315 will fit a 8 inch but it comes down to how close to the BJ it would be... I figure its a 12.5 inch tire meanins it'll hang over 1.25 inches on both sides of a 10 inch rim, whereas it would hang over 2.25 on an 8 inch rim. Curently I have about a half inch between the BJ and my 285 which hang over the rim by 2.11 inches and the 16x10 would have the same back spacing as i do currently with the stock backspace and a 1.5 inch spacer. So the question is with a tire 1 inch taller and .15 inches wider would it clear the BJ? Looks as if i might need some grinding...

[MrSmithsTB]

Only way to really tell that is to do it. If you have more than .15" clearance and the tire doesn't experience too much cupping, I would imagine .5" ball joint clearance to be sufficient. If not, no harm in .25" of grinding.
