    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.

    Charcoal Mammoth 4x4 Boulder Beadlock. Upgrade your JK with the Mammoth 4x4 Boulder Charcoal Wheel from ExtremeTerrain. This Mammoth 4x4 wheel features classic Wrangler styling with simulated bead locks for an aggressive look . 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. This Boulder wheel is completed in a durable charcoal powder coat and features a polished lip with simulated bead locks to create a bold off road appearance. It comes equipped with a matching Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

    LT265/70R17 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.

      Nice rims

      Love the rims mine are the old silver ones they don’t carry anymore. So I bought a charcoal one and painted it silver to match. See when I bought my rims I did so not thinking and only bought 4. No big deal I was running stock tires on then and the spare was silver also. When I lifted it and went to 35’s I still had a tiny spare on a factory wheel. I’m extremely happy now.

      Great looking wheels at an affordable price

      The wheels arrived quickly (and free shipping too!). They look great on my 2018 JL Rubicon Unlimited. I like way that the silver lip delineates the dark wheel from the dark tire. I wouldn’t hesitate to recommend these wheels to anyone.

      Awesome wheels

      I wanted a classic 5 spoke wheel, but one with some attitude. These wheels look fit the purpose perfectly and look great with the offset and 33 X 12.5 Ridge Grapplers. Delivery was quick too. I can't recommend them highly enough.

    Hi, Stupid question I purchased 4 of these a few years ago in silver, awesome wheels love everything about them easy to balance and look outstanding. my fault I didn't purchase a fifth wheel for the spare now I regret it and you no longer carry the wheel in silver that I see. Is my only option to buy a charcoal wheel and have it painted silver ? or do you still have silver available in a 17X9 thank you. love the wheels

    • Unfortunately we do not offer these wheels in Silver. At this time, they are only offered in Charcoal and Black in 17x9.
