I installed them with 33x12.50's with no lift since all 4 tires were balled when I got the jeep. An once I install the 4in lift I'm gonna replace them with 35's and 20's but they look great.Helpful (0)

Stylish wheels for not a lot of money
Picked up a 5th rim for a used TJ I purchased that had these on 32" tires. They look great on a gold Sahara. Extra rim complimented the look, really nice rims.Helpful (0)

I ordered 5 of these, look great in the online picture, but when they arrived they look even better. I will be mounting Patagonia extreme terrain MT tires on them as soon as my balance beads arrive. Thank you Extreme Terrain for the quick service and excellent products. I will post pics of them when installed on my YJ.Helpful (0)

I ordered a set of 5 of these and I couldn’t be happier. They look fantastic and have the backspacing to stop the rubbing I was getting on the stock wheels. I ordered mine as wheels only and took them to a local discount tire shop where I got the a new set of BFG KO2s mounted and installed. Be sure to order lug nuts because they aren’t included. Overall I’m really glad I went with these. They’re a good price and really seem to be a all around great product.Helpful (0)

What is the backspacing and off set on this wheel?
Backspacing will be 3.7" and offset will be -19mm.
I have a 2003 TJ with a 2.5” lift kit. Will these fit?
Yes, the Mammoth Boulder Black 15x8 Wheel & BFG KM2 33x10.5- 15 Tire Kit will work with a 2.5" lift.
I have a 2005 Unlimited with my factory rims I can not use 33x12.5x15 because the rear rub. Will these space it out enough so that I can upgrade my tires also?
Hello, yes, this wheel will space out enough so you will not have any issues with rubbing.
Are these tires good for highway driving? I drive about 4 hours to college and 4 hours back, and I come home quite often. My current tires have given out on me and cannot make the drive safely anymore? If not these tires, please give recommendations! Thanks!
These wheels would be just fine for highway driving. The tire on this wheel looks to be a mud grappler. Being a mud tire, of which can be pretty loud on the highway. We would suggest all season or all terrains if you're doing a lot of highway driving.
I have 2005 Jeep Wrangler Unlimited Tj. Will this tire and wheel size require a small lift or will it be not rub without one?
We would recommend running at least a 2-inch suspension lift with these wheels and tires to have proper clearance and reduce the possibility of rubbing.
Fitment will vary based on exact model year.
The wheel can be used with 30" tires, however, we would be unable to guarantee fitment on the XJ model.
It would depend on the tire manufacturer, some tires require a minimum of a 9" wheel for a 12.50 wide tire and some require an 8" wheel. We would suggest confirming with the tire manufacturer of the tires you are looking to install to confirm what they require for their tire.
The center caps for these wheels are specifically designed for Mammoth Boulder wheels. We cannot guarantee fitment of these center caps on other wheels.
These wheels will come with the center caps.
These wheels have a 3.7" backspacing.
You can build your own kits by adding the wheels and tires to your cart. Don't forget to add Mounting and Balancing and TPMS if needed along with lug nuts.
The offset for these wheels is -19mm (-0.7"). Keep in mind we typically offer this information in the "tech specs" on any wheels' individual product page.
This would work just fine without any modifications or spacers yes.
Yes, a 30 x 9.5 tire would fit this wheel.
