This set was perfect for my jeep. It made my jeep look 10x more aggressive. It also gave me a little more ground clearance from what I previously had.

Hello, do these wheels come equipped with dual valve stems? If not do any of the wheels you stock include this feature?


  • The Mammoth Boulder Black Wheel will only have provisions for one valve stem. We do not currently offer any wheels with provisions for this.

    Lovey black wheels

    These wheels from mammoth look awesome! When I first got them delivered, one had a bend in the rim and a stress crack. Extreme terrain sent me a label to ship it back, no cost to me and sent another one right away. Not one problem since and its been about 3 months now. Did have to use a lot of weight to balance but they balanced well. Would totally recomend these!

    Great Looking Wheels!

    I ordered this set of wheels for my '97 TJ, and couldn't be happier. Low cost, great brand, and they look fantastic. Made "Betty" a completely different looking Jeep, and for the better. I made sure to get a 5th wheel for the spare, so it can be displayed on the back. No tire cover needed to hide anything ugly on this Jeep! Did I mention that I received them in just two days? Thanks Extreme Terrain!

    16x8 w/ 33" Mickey's

    Absolutely bang for your buck. Have received many compliments from co-workers and general public on the look of the wheels and how much better they changed the overall appearance of my '02 TJ. Would recommend to other to purchase the wheels. The wheels themselves fit perfect and have no tire rub w/ a 3" spring & body lift. Only, somewhat opportunity was the limited amount of 16" tires available on, but I'm satisfied with the selection I made.

    Love my wheels

    Bought the black wheels and mounted them to 265/75/16 Mickey Thompson mtz p3s. Makes the old yj look great. Jeep has a 2.5" lift. Great size wheel and tire set up for this lift, aggressive look but still rides nice. I originally ordered the charcoal wheels but they did not look right with my hunter green jeep, awesome looking wheel just not what I wanted. Return process was easy and return shipping was very reasonable. These are awesome wheels for the price. Thanks extreme terrain.
