      The wheels are mounted on the tires and look unbelievable, not mounted on my Jeep as I’m still working on the underside. I will follow up with pictures as soon as I can.

      Review from Mammoth Boulder Black 15x8 Wheel & Mickey Thompson Baja MTZ 33X12.50R15 Tire Kit (87-06 Jeep Wrangler YJ & TJ)

      Great Tire and Great Price

      Just had these tires placed on our 95 YJ after 4 inch lift was installed. Black rims go well with the blue color of our Jeep. Ride nicely and not too loud when driving as well. When comparing these tires to other sites this was a great price and customer service was very helpful in helping to decide if 33s were the right size based upon the type of lift being installed. We get many compliments!

      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.

      Fantastic Wheels for a TJ!!!

      These wheels gave me the exact look I wanted for my TJ. They look fantastic and fit perfect without any lift. They are also lighter than the stock wheels. You can beat the price.

      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.
