            I love the look of the faux bead lock wheels and the falken’s are a nice quite ridding and attractive tire.

            Review from Mammoth Boulder Beadlock Style Black Wheel - 17x9 (18-20 Jeep Wrangler JL)

            Great looks

            After many reviewing many photos of different styles of wheels, I decided on the 17x9 Mammoth Boulder beadlock wheels. Very satisfied with my selection on how they look on my Jeep Wrangler JL in the Granite Crystal Metallic color. Also, my new 33 inch x 11.2 inch tires fit well on the wheels and the ride is better too.

            Great look for a great price!

            The visualizer didn't do these wheels justice when I was browsing the site! They look even better in real life! The build quality is great, and I've gotten several compliments since their debut. I've only had them on for two weeks, so they haven't been off road yet, but they seem very stout and should be able to take anything the trail can throw at 'em!

            Review from Mammoth Boulder Beadlock Style Black Wheel - 17x9 (18-20 Jeep Wrangler JL)

            Love these wheels.....

            The Mammoth Boulder Beadlock wheel has a very simple design with an aggressive look. They are very easy to clean and the weight of these wheels is much lower compared to other manufacturers. In my opinion they look much better in person than some pictures show. Honestly can’t find anything negative to say about these wheels. Extremely happy with the purchase.

            Wheels look absolutely great. Need to wear off the current rubber before I can mount these with new tires, but the wheels were a nice birthday gift and look great in the garage. And talk about incredible fast shipping. From order to delivery was 2 days.

            Assuming these hold up well, I really like them - just got them on my jeep and they look great. Seem solid, and not too heavy. Using them on my black 2 door JK. Will update if I have any issues.

            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!

            These wheels are much better in person; absolutely love them. Wife wanted all black, but talked her in to these with the silver beaded trim. Great option. One of my favorite set of rims.

            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.
