        Light Weight and great Looks!

        These wheels are very light weight! Nice finish, balanced with less than an once of weight. You will need to order Lug Nuts, unless you plan on running what you already have. With the low price on these Mammoth Boulder wheels, you almost cant afford not to buy them!

        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.

        5 2003 Wrangler - Jdog


        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.
