        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.

        Will the stock JK lugnuts work on this wheel?

        • Hello, yes you can use the stock JK lug nuts on these wheels.

        would these fit a 2018 JL unlimited sport? 17X9 wheel thinking about 33" tires. what do you suggest??

        • Yes! These Mammoth Boulder Black Wheel will fit your 2018 JL just fine and should have no problem with 33" tires at stock ride height.

        Hello. I am thinking of purchasing these wheels and new A/T tires for my stock 2010 Wrangler Sport (2-door). What is the largest recommended tire size that would fit without any rubbing considering I have all OEM parts (e.g., bumpers), and without adding a lift kit or other add-ons? And which tire do you recommend? Thanks,

        • We would suggest no larger than a 32x12.50 with the Mammoth Boulder Black Wheel - 17x9 on a stock Jeep. Two popular options for the all terrains is the BF Goodrich All-Terrain T/A KO2 and the NITTO Ridge Grappler Tire.

        Do they include black lug nuts? Or do those need to be purchased separately?

            Review from Mammoth Boulder Matte Black Wheel - 17x9 (07-18 Jeep Wrangler JK)

            Just what I needed.

            I was looking for a lightweight wheel, preferably a five spoke. I researched several different online stores, as well as brick and mortar ones. These were lightweight, as well as reasonably priced. I ordered on a Saturday night, and received them by the following Thursday. I mounted 35" Falken Wildpeaks on them, and they look great on the '16 JKUR

            What a difference!!!

            I had my eye on these wheels for quite a while before I decided to pull the trigger. I liked the looks of this wheel and the fact that they were already properly offset made the decision that much easier. I am very pleased with this purchase and even more pleased at how much more appealing it made my Jeep look. The price was right and the shipping was fast. I Would highly recommend this wheel if you want to turn some heads.

            Worthy upgrade

            I was looking for an inexpensive wheel to update the stock JK aluminum one. These fit the bill! They look great and have the perfect amount of offset so I was able to eliminate the 1.5 inch spacers I was running. Quality and finish got five stars for now but how they hold up long term is yet to be answered.

            Good for the money

            Quality of the wheels finish is not very good - one of them had a long hair that had been painted onto the wheel. When removed, it took some of the paint with it and left lines of raised paint where it used to be. I didn't contact ET about this, as I didn't care enough to ship it back and wait for a new one... it became my 5th wheel spare. Paint seems "soft" - already have my first chip, with no exciting 4x4 story to tell for it - just normal road use. Now, aside from all this - I get compliments everywhere I go, and everyone agrees they look badass.
