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.

Are wheel spacers needed when running 35/12.50-17 tires?

  • Hello! Wheel spacers are not needed to run 35/12.5/17 tires, all you need is a lift of at least 2.5 inches!

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.

Do jeep center caps fit these rims? Also I am purchasing a JL what is the back set?

  • Factory Jeep center caps will not fit on these wheels. These wheels also have a backspacing of 4.7".

WOULD I NEED SPACERS TO RUN A 37 12.50 17 TIRE?

  • The Mammoth Boulder Beadlock style wheels can run with a 37 tire. The only issues will come from the lift size the Jeep has, and other modifications. For more assistance determining the best method to run 37s on your Wrangler please Chat in or Call to speak with an agent.

    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.

    Mammoth Boulder beadlock style charcoal rims

    Absolutely love these, the pictures do not do justice for the color online. Not too fancy/flashy but exactly what I needed because I wasn't going to put wheel spacers on. Very close match to the Granite metallic crystal color of my JL Wrangler. I put on 315/70/17 Cooper Discoverer STT Pro

    2nd Times a charm.

    I ordered a set of 5 and 4 of 5 had dings, scrapes, and what looked to be road rash. They came from Mammoth that way, not due to handling issues from shipping, or E.T. ExtremeTerrain took care of me and switched them out. Looked just as I hoped.

    Tires and rims

    Rims and tires look nice and I am happy with them. But I have to take one tire in to get it rebalanced it only had one wait on the rim when the rest of them had six just want to make for sure its balance right before I put it on my Jeep. I will let you know the rest when my Lift gets here still waiting on it.

    Review from Mammoth Boulder Beadlock Style Charcoal Wheel - 17x9 -06mm Offset (07-18 Jeep Wrangler JK)

    Awesome Wheels

    I was disappointed when AEV discontinued their Argent colored Pintler wheels. I especially wanted that beadlock look and was having trouble finding them. I found these Mammoth Boulder Beadlocks and boy am I happy AEV discontinued theirs. It's half the price, a better look IMO, and really impressive in person. I see a lot of AEV wheels out here in Utah and not a lot of the Boulders, which is nice to not be a part of that ubiquitous look. The wheels aren't heavy, but aren't light either. I've taken them offroad twice now and don't have any complaints. I haven't really scuffed or scratched them to see how they behave when that happens. If you're looking for a GREAT gunmetal beadlock looking wheel for one heck of a price, look no further. Buy these! You won't be disappointed.

    2012 white sahara

    Went with the charcoal gray instead of black because everyone has black and gray is easier to keep clean . If you ever had black rims they are a lot of work to keep clean . Besides that they look awesome . Stayed with 17” with larger tire . Stock tire was 255 and went with 285 Nitto . The rims were delivered in two days and the price was right .
