what is the offset and/or backspacing of this wheel? does the 17" wheel have the same backspacing as the 16"

  • Hello, on the Mammoth Boulder Beadlock Style Black Wheel - 16x8 (07-17 Wrangler JK) the Backspacing is 4.5" (114mm) and the Offset is 0mm (0") the 17 inch wheel has a Backspacing of 4.7" (121mm) and Offset of -6mm (-0.2")

I would like to run 33" by 12.5" tires. can I do this with 16" rims? Is there any benefit between 16 / 17 with the same total height. (I like the look of smaller rim w/larger tire)

  • If your looking to run a 33x12.5R16 you would want to run a 305/70R16 tire. The benefit for running a larger tire is when airing them down for heavy off roading, and it can provide a softer ride feel on roads.

Will the original “Jeep” center caps fit on this wheel?

  • Unfortunately, the Mammoth wheels will only work with Mammoth center caps.

I have a two door Wrangler JL with P245/75R17 112T tires. The current rim is 17 X 7.5. Will theses tires fit on the Mammoth Boulder Beadlock Style Wheel - 17 X 9? (Irem J100635)

  • Yes, a 245/75R17 will indeed fit on the 17x9 Mammoth Boulder Beadlock Style Black Wheel but a 265/70R17 is recommended.

Hi I just put on a teraflex 3" suspension lift on my jk 2012 Sahara . I want to run 35s for tires. People say I need a off set or spacers 1.25 or greater. Are theses rims off set and how much could I run those and be fine turning tight turns with no rub?

  • These wheels do have less backspacing than the factory wheels and would allow you to use up to a 12.5" wide tire.

    Review from Mammoth Boulder Beadlock Style Black Wheel - 16x8 (07-18 Jeep Wrangler JK)

    Just (almost) perfect!!

    Super cool rims and offset is perfect at least when paired with 285/75/16's. One came with just a little ding in it which doesn't affect anything but aesthetics (and barely noticable) otherwise they would be a full on 5 stars.

    Excellent!

    Was a bit skeptical about the looks compared with similar styles wheels. But after these wheels were mounted, even the Jeep Dealership was excited. No pictures, including the catalog’s pictures do these wheels justice. The backspacing was perfect. Ya gotta see them for yourself. Glad I made that choice!

    I just got the 17x9's put on my Jk. With no lift, I put 285/70r17's and they great! I had one damaged in the first shipment, but the reps were very helpful in getting me another one quickly. I'd definitely recommend these!

    Mammoth Boulder Beadlock Style Black Wheel

    These look great on my Jeep. The offset helped with the slight rubbing I was having with 35" tires on stock rims. I suggest black lug nuts to go with wheels.

    Nice wheel but poor shipping

    Had to order these wheels and new tires little by little for budget reasons. Finally went to un box all five wheels and get them mounted and balanced, one of the wheels was broken in the box. 1. My fault for not checking immediately after purchase 2. How does a steel wheel get shipped broken and no one notice? Super disappointed by this as I am on a budget build. All the years purchasing from extreme terrain, American muscle and American trucks...was not expecting this.

    Mammoth Beadlocks

    Purchased 5- Mammoth beadlock rims for my Jk Jeep. I was surprised at the quick delivery, not to mention the rep on the phone made ordering such a breeze. Pricing was not an issue because I know Extreme Terrain, good stuff / fair prices. Rims are on and look great, I also purchased 1-1/2" spacers to give a wider stance to my jeep.
