5 Top Rated Questions

The green TJ in the pics displaying the 15X8 wheels...are those 33" tires or 35"?

The TJ used in our product photo's of the Mammoth Boulder Charcoal Wheel is using 33" tires.

Helpful (5)

Will this work with 32x11.5x15 tires? I have a 2” OMU lift with stock fenders.

The 32x11.5x15 tires will work on the 15x8 Mammoth Boulder Charcoal Wheels.

Helpful (1)

Do lug nuts come with wheels and tires? If not do any stock wheel lug nuts fit?

Thank you for your question! Lug nuts do not come with the wheels and tires, and the stock lugs will work in conjunction with these aftermarket wheels.

Helpful (1)

If I mount a 33x12.5x15 tire on this wheel, will the 3.7 inches of back spacing be enough to keep the tire from rubbing my control arms or shock mounts while turning? I've heard that anything less than 4 inches of backspacing will work, but I just want to be sure.

Yes that will work just fine. We typically say to have at the most, a 4.5 inch backspacing to safely fit a 12.5 inch wide tire, so that 3.7 being lower would work out perfectly.

Helpful (0)

Are these available painted silver? My jeep is black, and I think silver would be a better color combination.

The Mammoth Boulder Charcoal Wheel are currently not available in silver, but you could have them painted before install.

I love the look of these wheels but I was wonder if they will work with the spin free locking hub conversion kit from Yukon. I have a 2004 Rubicon and with this manual hub conversion and really want these wheels. Thanks for your reply! 1 answer

Hello, unfortunately we did not test fit this wheel with the spin free locking hub conversion kit from Yukon, so we wouldn't be able to guarantee fitment. but the center bore opening is about 2.45 inches in diameter.

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.

Review from Mammoth Boulder Charcoal 15x8 Wheel & BFG KM2 33x10.5- 15 Tire Kit (87-06 Jeep Wrangler YJ & TJ)

Great wheel and tire!!!

The tires arrived quickly and were balanced perfectly! I only have about 50 miles on them so far but the KM2s ride great and the wheels look awesome! 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!
