Recommended 5th Wheel Upgrade. When increasing the rolling diameter of your Jeep Wranglers tires it is recommended to upgrade your spare tire at the same time as the stock spare may be too small to be used. And besides a big meaty spare looks intimidating on the back of your Wrangler.

This Mammoth 4x4 wheel features classic Wrangler styling with an aggressive spin made to take on the trail. Specific to your Wrangler, it features a hub centric design to provide the reliability you need on the highway or off the paved path for a bold look no matter where your tire tracks end.Completed in a durable matte black powder coat for a rugged off road appearance, this Mammoth 4x4 wheel is the perfect addition for the Jeeper looking for a custom styled wheel without a daunting price tag.  It comes complete with a matching Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

LT315/75R16 BF Goodrich Mud-Terrain T/A KM2. BF Goodrich Mud Terrain T/A KM2 is the end all in off road capability. You'll never doubt traction on the trail with this tire's aggressive side wall lugs and self cleaning dual compound tread design. Your Wrangler will conquer climbs and pits and any obstacle with BF Goodrich's linear flex zone which allows this tire to conform to obstacles and grab the trail during aired-down crawling and driving. TriGard 3-ply construction and a chip resistant compound protect this tire from any trail hazards you run into, including cuts from rocks or boulders.

          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 Extremeterrain.com 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.

          Awesome

          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.

          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 ExtremeTerrain.com, but I'm satisfied with the selection I made.
