You are correct. The rubi wheels are 7.5. I know there were some model/year variations for wheel diameter but I can't remember if there were for width. I bet Eddie's tech sticky lays it all at.

WHEELS & TIRES
Q: Do tires measure up exactly to what is listed on the sidewalls?
A: No tire measures up to what is listed on the sidewalls. Most tend to come up way short of what is listed. Having said that, when discussing lift kits and how big of a tire you can run, you should ONLY go off of what is listed on the sidewalls and NOT the actual size of the tire. ALL lift kit/tire size discussions revolve around advertised tire size and NOT their actual size.
Q: What is the biggest size tire I can fit on my stock Jeep JK Wrangler?
A: The largest tire size that the factory recommends is a 255/75R17 (which comes standard on Rubicon models) or a 32x10.50. However, there are many Jeep JK Wrangler owners who are currently running as big as 285/70R17 or 33x10.50's with little to no rubbing issues. PLEASE NOTE: When discussing tire size, DO NOT take into consideration what the "actual size" of the tire is but rather, just what is listed on the
Q: What is the biggest size tire that I can fit with a 3" lift?
A: 35" tires and depending on what lift kit you have, you may still experience some minor rubbing up front at a full flex and when turning. PLEASE NOTE: When discussing tire size, DO NOT take into consideration what the "actual size" of the tire is but rather, just what is listed on
Q: What back spacing will I need on my wheels in order to clear 12.50 wide tires?
A: I would recommend that you do not exceed 4.75" of back spacing and even at that, you may still have some minor rubbing up front at a full turn. Also, I would recommend that you do not go any less than 3.75" as anything less would cause your tires to stick out very far past the fender flares. Any back spacing within this range should work out great. PLEASE NOTE: When discussing tire size, DO NOT take into consideration what the "actual size" of the tire is but rather, just what is listed on the sidewall.
Q: Are wheel spacers safe to use or do they cause extra stress on your axle or wheel bearings?
A: High quality wheelspacers, the kind that bolt up to your axle first are no more dangerous or cause any more stress to your axles then would a wheel with less backspacing. Anyone who tries to tell you otherwise doesn't know what they're talking about and I have yet to hear a single good or specific explanation as to exactly how they are worse. Just to be clear, the cheap-o spacers (the kind that you can get at PepBoys and are sandwiched between your wheel and axle using the existing wheel studs) are in fact EXTREMELY DANGEROUS. These cheap-o spacers leave little thread for your lug nuts to hold onto and can fail.
Q: What are all the factory wheels that are available for the JK?
A:Factory wheel type and sizes listed below:
X Standard
Painted Steel - Size 16 x 7.0
X Optional
Painted Cast-Aluminum - Size 16 x 7.0 (2007)
Painted Cast-Aluminum - Size 17 x 7.5 (2008)
Sahara Standard
Painted Cast-Aluminum - Size 17 x 7.5
Sahara Optional
Painted Cast-Aluminum - Size 18 x 7.5
Rubicon Standard
Machined Cast-Aluminum - Size 17 x 7.5
Q: Are all rims the same or is there a certain type of rim for offroading?
A: So long as you can mount your tire on it, a rim is pretty much a rim. Some Jeepers prefer to run steel wheels as they are typically much more affordable, are easy to touch up and will bend as oppsed to breaking but, they also tend to be heavier than aluminum. The one thing I would recommend is that you try and get a rim that is about 8" in width. The narrower width will help keep your tires from loosing a bead when aired down for the trail.
Q: How do you determine what size tire will fit what size rim correctly?
A: Typically, most off road tires come in a 12.50" width and for the most part, a 10" wide rim is what you would want. However, unless you are running beadlocks, I would recommend that you select a wheel that is 8" in width or there abouts. When aired down for the trail, the narrower width will help prevent your tires from loosing a bead. [/quote]

I'm glad you posted a pic of 37s on a stock rim. I was having a hard time believing it.
