      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.

      Matte Black Mammoth 4x4 Type 88. Take your Jeep to a new level of style and performance with the Mammoth 4x4 Type 88 Black Wheel from ExtremeTerrain. This Mammoth 4x4 wheel features aggressive styling with a modern 8 spoke design to take on the trail head on. Specifically designed for your Jeep, it features a hub centric design to ensure stability and reliability on and off road. This Mammoth 4x4 wheel is completed in a durable matte black powder coat for a rugged off road appearance and features an aluminum lip accented by gun metal inserts between the spokes that are easily removed and painted for a custom look. It comes complete with a matching black Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

      35x12.50R17LT 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.

        Better then picture

        I was worried with choosing my wheels because you can’t see them in person. I ended up choosing these over the fuel Mavericks and boy am I happy with these. They look even better in person and make the Jeep look much better then stock wheels. Highly recommend anyone who is considering these!

        Mammoth Type 88

        These wheels are awesome! Love the option to customize the trim color. The only downside are the center caps. They just snap into the wheels. Not sure how secure that are. I did have an issue with a couple of center caps that had been damaged during shipping or packaging, but customer service took care of it and sent new ones.

        Looks good, great price

        Good looking wheel especially for the price. I had ET mount and balance them on wome tires and they came out great. The only thing i didnt like is the stock lug nuts do not fit the in space provided on the wheels. Had to spend about $40 for some lug nuts for all 5 wheels.

        Looks great for a budget wheel

        I went with these cause they looked good and they are quite cheap. Work great except the insides scratched fairly easily when they got some mud on them. Also the hub caps snap in so they break very easily.

      • Hello, on the Mammoth Type 88 Black Wheel - 17x9 (07-17 Wrangler JK) if you put a 315x70R17 tire on it it will come outside the stock Fender a bit.

      Will the 16” wheel fit on a 2019 Wrangler?

      • At this time we only offer wheels larger than 16" to clear the brakes. At this time we do not offer a set of 16" wheels that will clear the JL brakes.
