    I want to put 32x11.5 mud tires on these wheels. Will they fit on the stock spare tire carrier?

    PatrickW

    • Theses Mammoth rims with a 32x11.5 tires will work with the stock spare tire carrier. We do recommend upgrading the hinges if you are going to retain the stock carrier.

    • A recovery Jack mount such as the RedRock 4x4 Extreme Recovery Jack Spare Tire Mount can be used to mount a Hi lift jack with the Mammoth Boulder Black Wheel. https://www.extremeterrain.com/redrock-4x4-tire-jack-mount-j100785.html

    Can you get different center caps logo color? I would prefer the Mammoth logo to not be white. I like the logo but maybe grey or something.

      Great wheels.

      I put these on my YJ and they look great. The chrome valve stems that came with the tire/wheel package seems like a strange decision though. Black chrome would have looked much better.

      Nice Wheel

      This is a really nice looking wheel. I only bought one for now because I had no spare. I really like it and I'll be buying 4 more when I need new tires so I will have these all around. But for now, It looks great on the back of the Jeep.
