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 factory 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 Boulder Beadlock. Upgrade your JK and JL or JK and JLU with the Mammoth 4x4 Boulder Beadlock Style Black Wheel from ExtremeTerrain. This Mammoth 4x4 wheel features classic five spoke 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 features a polished lip with simulated bead locks to create a bold off road appearance. It comes complete with a matching Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

LT305/70R17 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.

Will this fit a 265/70/R17 121/118P 10 P.R. on a lifted TJ?

  • These mammoth wheels are designed for the JK and JL platforms, and would require a wheel adapter. Though you would however be able to mount that size tire onto them.

    Awesome Wheels

    Assuming these hold up well, I really like them - just got them on my jeep and they look great. Seem solid, and not too heavy. Using them on my black 2 door JK. Will update if I have any issues.

    Excellent!

    Was a bit skeptical about the looks compared with similar styles wheels. But after these wheels were mounted, even the Jeep Dealership was excited. No pictures, including the catalog’s pictures do these wheels justice. The backspacing was perfect. Ya gotta see them for yourself. Glad I made that choice!

    I just got the 17x9's put on my Jk. With no lift, I put 285/70r17's and they great! I had one damaged in the first shipment, but the reps were very helpful in getting me another one quickly. I'd definitely recommend these!

    Mammoth Boulder Beadlock Style Black Wheel

    These look great on my Jeep. The offset helped with the slight rubbing I was having with 35" tires on stock rims. I suggest black lug nuts to go with wheels.

    Nice wheel but poor shipping

    Had to order these wheels and new tires little by little for budget reasons. Finally went to un box all five wheels and get them mounted and balanced, one of the wheels was broken in the box. 1. My fault for not checking immediately after purchase 2. How does a steel wheel get shipped broken and no one notice? Super disappointed by this as I am on a budget build. All the years purchasing from extreme terrain, American muscle and American trucks...was not expecting this.

    Mammoth Beadlocks

    Purchased 5- Mammoth beadlock rims for my Jk Jeep. I was surprised at the quick delivery, not to mention the rep on the phone made ordering such a breeze. Pricing was not an issue because I know Extreme Terrain, good stuff / fair prices. Rims are on and look great, I also purchased 1-1/2" spacers to give a wider stance to my jeep.

    Great Look w/ 2.5 Coil Spring Lift 35 Inch Tires

    Wheels and tires look great. Added Goodyear 315/70R17 Duratracs to make the set. Mammoth kept it simple with the design. It not only looks good, but should be easy to clean with no hard to reach areas. One rim out of the five ordered had a very small dent. Extreme Terrain took it right back and shipped out another one. As soon as I gave it to UPS with Extreme Terrain's shipper information, Extreme Terrain sent out the new one before the damaged one was received by them. In the end, it was a spare so it really did not keep the vehicle from being driven.
