        Wow they look good

        These wheels look great. I am so happy with how they turned out. I put them on 33x12.5 tires so they will fit and they look great. I couldnt be happier with such an inexpensive item and such a good product. I didnt want a 300$ wheel. not functional for what i want to do with my jeep.

        Still a project!

        There was a small chip on the very outer edge of one of the rims but once the tire was mounted it was no longer visible. Overall I'm very pleased. They look great with the Falken Wildpeak 32's.

      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 (8)

      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 (3)

      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 (2)

      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.

      Will the 15 x 8 wheels work on a 2000 Jeep Wrangler Sahara with 31-10.5-15 tires? (No lift - stock rims currently)
