    These wheels have a very high "bang for the buck" factor. I love the overall design and look. I received compliments the very first day of having them installed! There are some minor blemishes in the finish is the only reason for not getting 5 stars.

    Outstanding!

    I had these wheels built as part of a tire/TPMS sensor?wheel package. My 2010 JK 2 door looks fantastic with these wheels. Great fit and finish. Extreme Terrain did a fantastic job of building these wheels/tires. The TPMS sensors worked right away. Everything was uber high quality. Love the look and finish. I'd highly recommend these.

    just as a FYI you can not use the rear tire mount for your High Lift Jack on these tires. The center hole is to small

    Awesome wheels!

    This is the first set of aftermarket wheels I've ever purchased, with that being said , I love the way these look on my '17JKU. Get lots of looks around town and love how they accent the color of my silver Jeep.

    Good looking and perfect wheels for JK.

    XT cs was great! But one had a chipped inside the inner lip. After contacting XT with pics, they gave me a credit for it. We're all aware that these can be damaged due to shipping, so why not protect the inner lip as well? Just like the outside lip. Reducing the chance of getting it damaged during transit and eliminating the hassle on claims. I'm sure additional plastic lip protector wouldn't cost as much as the credit that XT gives away just to satisfied their customers. All in all I'm glad I got these in charcoal to be a little different! I will definitely get these again once I get another Jeep.

    Beautiful 5-spoke!

    I'm a fan of a more simple wheel and have always been a sucker for a 5 or 6 spoke wheel. These wheels are beautiful and mated perfectly with my 285/75-R17 Ridge Grapplers. The charcoal finish looks awesome with the Granite Crystal Metallic Jeep color too. It's not a dead match but very similar. Couldn't be happier!

    Good Wheel with Some Imperfections

    If you've read other reviews then you know this is a great looking wheel and the offset if perfect for the Jeep. Some reviews mention they got one or two wheels with a small gouge in the lip. I got one of those in my black ones. It's small enough that doesn't warrant a return and it's didn't affect mounting but it just makes the lip look out of round. Other than that the wheels are good.
