        Perfect to give your Wrangler an aggressive look!

        These wheels have a -6 offset, so they poke out and look super aggressive! They look way better than I could've asked for! Definitely worth it! Especially with how affordable they are! We have a JL Sport S and these wheels with 33x11 tires, there is 0 modification you need to do for them to fit. Still plenty of clearance!

        Wrong Wheels sent three times!

        I ordered 5 Mammoth Boulder Matte Black Wheels and have yet to receive the correct order. Initially I was sent three matching Matte Black wheels and two different semi-gloss wheels. When I returned the two incorrect wheels I received one Matte Black and one semi-gloss wheel. I returned the incorrect semi-gloss wheel to receive the exact same wheel in the exact same box!!! As you can imagine I am not happy. Just got off the phone with customer service, hopefully I will get the correct wheel this time.

        Same wheel two prices???

        I purchased 4 Mammoth Boulder Black wheels for 18-20 jeep jl, $148.99 ea. They sent me an email listing the 4 wheels as 07-18 JK wheels which are priced at $129.99.I called and was told they are the same wheel. Does that sound right to you? I paid $76. more for the same wheels. Sorry cant tell you about the product the service got in the way.

        Great wheels

        Changing from stock wheels to Mammoth Boulder matte black 17 X 9 wheels, paired with Mud Claw 285 70 R70 tires was awesome. Wanted a 5 spoke black look and couldn't be happier. Great product.

      5 Top Rated Questions

      Will P285/70/R17 fit without rubbing anywhere at full flex with no lift or spacers?

      • Thank you for your question! A 285/70R17 is about 32.7" tall and about 11.2" wide. With this wheel you will have enough backspacing that you will not need spacers. At full flex with no lift I would not recommend an almost equivalent 33" tire because there will be interference with stock fenders.
