I have a 98 TJ with a 2.5" lift. It has stock steel 15x7 wheels with 31x10.50x15's. My question is will these stick out farther than my factory 3.5" fender flares?

  • Assuming you are going to run the same size tire on the Mammoth wheels the new set up is going to stick out about 1.75 inches more than your current set with the factory wheels.

In one of the photos, I noticed that the outer rim insert is orange. Are these sold in different colors, specifically Forest Green Pearl?

  • The inserts are not available in colors other than black, however, they can be removed and painted to the color of your choice.

On a 5X4.5 bolt pattern, what does the 4.5 stand for ?

  • A 5X4.5 bolt pattern means that, with the 5 bolt holes, if you were to draw a circle connecting the dots it would come out to 4.5 inches in diameter.

    Very good looking and quality wheels except the center hub is plastic and you can pop them on and off easily. But that would not discourage me from buying them again.

    Badass Wheels

    They are so clean and will not disappoint anyone who buys them. Receive a lot of compliments on them. Look extremely good on my BFG KO2s. The only problem I have with them is that when you go mudding, its really hard to get rid of the mud inside without having to remove the tire to clean it.

    Review from Mammoth Type 88 Black Wheel - 15x8 -19mm Offset (87-06 Jeep Wrangler YJ & TJ)

    beware the flimsy center caps

    center caps snap on from the outside - they are not secured by the wheel in any way, shape or fashion. you can easily pull them off from the outside with your fingers, hence, they VERY easily fall off on their own just driving down the road. I purchased the wheels and center caps approximately one month ago and have already lost two caps. I do zero off roading, the majority of my driving is highway, with some city. i would not have purchased had I known.

    Review from Mammoth Type 88 Black Wheel - 15x8 -19mm Offset (87-06 Jeep Wrangler YJ & TJ)

    NOT BAD FOR THE MONEY

    The rims were definitely a good price, plus I got them on sale and saved an extra 60ish dollars. They extended my tires a good 3" outward on my 31s. I could easily put 33s on without buying spacers. I was a bit disappointed that the center hub was plastic with a plastic chrome "Mammoth" logo. That will wear off with time. However, they definitely gave my 99' TJ a whole new profile.
