Wheel Tech; Rocky Mountain Wheels vs Moab Wheels?

Have a friend up the street who wants to know about the Alcoa Forged Aluminum Wheels (Part #52059705AA) that supposedly came on the Rocky Mountain Edition. Do they have the same back-spacing/offset as the Moab wheels that came on Rubicon TJ's?

She recently bought a Tomb Raider edition Rubicon but the PO had traded the Alcoa Wheels that it came with for a set of Moab wheels from a friends 2005 model Rubicon. Anyway, she wants to go back to the Tomb Raider wheels but keep her brand new 16" tires, and she's happy with her current width, offset, backspacing, etc.

She's found someone on a local Jeep swap shop FB page with a set that say they're from a "Rocky Mountain Edition" that we think were the same ones that came on the Tomb Raider models. The ad says they are 16".

Can anyone confirm that these will have the same offset/backspacing as the Moab wheels on her Jeep now? ...and if the specs are difference what is the difference going to be?


(I thought there was a page somewhere on JF with the various wheel specs but now can't find it, and always good to get confirmation anyway)

Thanks guys. Though there are no pictures in that, only broken links where pictures should be wanting you to pay to get to see the pics.

Hadn't thought about the photobucket BS. Should have thought of it though as that thread predates the ability to upload pictures direct to JF. Ryan created that thread I think. Will have to see if he can fix.

Also that sticky only list these wheels as being 15", we know the set she found for sale is 16" which also makes us wonder if the others specs could also be different.

Or the ad is wrong and RM wheels are 15" (which is I think is correct).

They have "16x8 Forged" engraved into the inside of the rim on the backside. I'm actually wondering if the seller is wrong and they aren't Rocky Mountain wheels but are actual Rubicon wheels. Which should be just what she wants except then the question would be do they have the same backspacing and offset as the Rubicon MOAB wheels... since she's upgraded to 33" tires with a lift that might be important.

The ad says they are brand new in the Chrysler/Mopar box marked part number 52059705AA

If they're 16" wheels, they aren't RME factory wheels. Only the TR edition had the 16" Alcoa wheels. The factory RME came with Alcoa and Ravine wheels (2005) and they are 15x8" with 5.5" backspacing.

I think we have determined they are actually Rubicon wheels from a Tomb Raider, so supposedly exactly what she needs HOWEVER we do need someone to verify the backspacing and offset compared to the Moab wheels she has now since she's got a lift and bigger tires. Can't imagine it being enough to make a difference but want to make sure before she forks out the $$.

Wish I could tell you for sure, but I'd bet it is the same.

Here you go.

If adventure is your style, Classic 8 TR-2 hot forged aluminum wheels are made for you. OEM standard on Jeep Wrangler Tomb Raider Limited Edition, this Classic 8 hot forged aluminum wheel is available to the aftermarket as well. Alcoa 16 x 8-inch (468521) fits other 5 x 4.5-inch bolt applications. That includes certain Dodge, Ford, Honda, Jeep, Mazda and Toyota models.

The new TR-2 wheels and axle end cover come clear-coated. They keep their good looks simply by washing with soap and water. Do not use abrasive cleaners or polishes on coated surfaces, including TR-2 wheels. Do not use Alcoa Aluminum Care System or PDQ Brightener on TR-2 wheels.


Like all Alcoa hot forged aluminum wheels, Classic 8 TR-2 wheels come with certain built-in advantages:


One-piece hot forged strength. Our one-piece design eliminates welds that concentrate stress where fatigue cracks can start. Hot forging aligns the metal grain in a uniform direction along the contours of the wheel, enhancing strength.
Good looks. This clear-coated Alcoa forged aluminum wheel shines like no painted wheel can.
Easy upkeep. Aluminum is naturally corrosion-resistant. Your good- looking Alcoa aluminum wheels never need sandblasting, priming or painting.
Improved handling. Alcoa aluminum wheels weigh less than comparable steel wheels, lowering the suspension’s unsprung weight. Lower unsprung weight allows faster suspension response, a smoother ride and improved grip in cornering.
No one knows more about high technology aluminum applications than Alcoa. After all, we invented the first commercial aluminum truck wheel in 1948. Today, we put that hands-on experience to work for you, making hot forged aluminum wheels for pickups, sport utility vehicles, motorhomes, buses, heavy duty tractor/trailers and more. Find the Alcoa wheels that fit your lifestyle.

Awesome. Appreciate it. Will let her know.

That's 1/4" inch less backspacing than the Moab wheels, so don't think that will be enough to affect her larger tires or lift. Not sure about the backspacing difference between the two, will have to look up the Moab again.

Well of course one wheel list offset as .5 (or is that 1.5, there is a 1 there but a space before the .5, 1.5 seems like a lot), and the other +12mm on the offset :P
