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 (6)

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 (1)

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)

Will these fit a 1998 ZJ? I believe they have the same offset and bolt pattern as a TJ.

We have not confirmed fitment on a ZJ. These are only guaranteed to fit Jeep YJ and TJ's.

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.

Item was packed well, feels well made, but powder coating was a little thin around the center cap so take care when mounting. Very pleased overall with the wheels.

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.
