        Big Difference

        Looking for new wheels can be hard when you only see a picture. So, even after I bought these I was just not sure how they would look on my jeep. I was not disappointed when I saw them in person for the first time. There were no issues with finish or appearance when they arrived. Each was packaged nicely.

        Fantastic Set for Price

        Super happy with this wheels/tires set for my '09 Wrangler JK. They look amazing and my Jeep rides smoother than ever. These were exactly what I wanted for my first set of after-market tires and wheels.

        Great setup

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

        5 2018 Wrangler - Mjmhomes

        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!

        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.

        Impressed and Excited

        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.

        Awesome Wheels

        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.

      Does the beadlock ring stick up above edge of wheel to where they hold water because it can't escape?

      • No, the wheels would not retain water in that fashion.

      Are these real beadlock wheels? Or just look like beadlock wheels?
