This Mammoth 4x4 wheel features classic Wrangler styling with an aggressive flare made to take on the outdoors. It's hub centric design provides the reliability you need on the highway and trail for a bold look no matter where your tire tracks end.Completed in a durable charcoal 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.

    35x12.50R15LT 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.

    Application. This 15x8 Charcoal Mammoth 4x4 Boulder wheel and 35x12.50R15LT BF Goodrich Mud-Terrain T/A KM2 Fits 1987 to 2006 TJ and YJ Jeep Wranglers.

      Good

      Tires are great. Wheels look good but the quality of the powder coat isn't the greatest but for the price I guess you can't ask for much. My only real gripe was I specifically requested that the white lettering be out but they installed them on the inside.

Absolutely no complaints Love ordering from Extreme Terrain they have great pricing and always have the stuff in stock unlike other big online retailers.

      Mammoth rims

      Installed the wheels and tires and I have to say they look great! The guys at Extreme Terrain helped me with my order and I could not be happier. Ended up using 33/12.5 dick cepek extreme country which so far have been great in and off road. One concern I had switching to a wider tire lugged tire was how it would perform in snow. Let me just say these tires are even better then my stock Bridgestones. Will defiantly buy again!

      I wanted something simple and different from all the black rims everyone is running now. The charcoal fit the bill and I think goes well with the khaki color of my TJ. I went with Blue lugs to Pledge my Allegiance to DUKE University. Great price point, I like them a lot,

      GREAT LOOK, GREAT PRICE

      This wheel is perfect! The 3.7" back spacing of the 15x8 Mammoth Boulder gave my TJ the aggressive stance that I was looking for. The finish is superb! The Mammoth Boulder Charcoal Wheel will look outstanding on any color Jeep. You can't go wrong when you purchase a set of these wheels. This is a high quality wheel at a very affordable price. I highly recommend the Mammoth Boulder Charcoal Wheel.
