Can you get different center caps logo color? I would prefer the Mammoth logo to not be white. I like the logo but maybe grey or something.

YJNewb

  • Hello, we do have different colored center caps. We have Red, Orange, Yellow, Green and Blue, as you can see here: http://www.extremeterrain.com/wrangler-jeep-tj-center-caps-9706.html Those are the center caps you can replace the Black one with.

I have a 2003 Wrangler , currently running 33x12.50/15 I don't like that wide tire look and don't know how to figure backspacing but with this package would this keep tire inside of flares ?

  • I too have the same question, we have a 2003 Wrangler currently have 33x12.50 not sure on the backspacing but will these wheels fit in closer to jeep ,

Would these wheels fit on a Jeep that is not lifted?

Anonymous

  • Hello, depending if you have a TJ or a YJ, if you have a TJ we would advise having at least a 2.5" lift, if you have a YJ we would advise having at least a 3.5" lift.

    Review from Mammoth Boulder Black Wheel - 15x8 Wheel - and Mickey Thompson Baja MTZ 31X10.50R15 (87-06 Wrangler YJ & TJ)

    Awesome, Well-Priced, Overall Easy Process

    I am new to the world of Jeeps, but I have to say I am really impressed by Extreme Terrain and their Tire Kits. I wanted to get the Baja MTZs after seeing some other Jeeps out there with them and falling in love with their aggressive styling, and then as I started to price them out, found this great kit with the Mammoth Boulder Wheels. They fit my Stock Lift 2005 Wrangler perfectly, and even gave it some extra height. I was momentarily scared that they would be too bit, but was assured by everyone that they would be fine and sure enough they were. Very pleased. BUT don't forget to buy lug nuts! I luckily remembered in time.

    1998 TJ

    Mounted these rims on my 1998 Wrangler. Look great! Running MT 33X12.5 Deegan 38 tires with a 4" Stage II Pro Comp lift. The back spacing on these rims is exactly what i was looking for: keeps the tires out of the suspension at full turn but doesn't push them so far out of the well they look like training wheels.

    Just finished installing these Tires and rims. They look great on my wrangler. If I had to complain about 1 thing it would be that they used chrome valve stems on blacked out rims. Not sure what they were thinking.

    Mammoth Boulder black wheels

    I've been looking for a while for some wheels that are similar to the 03-06 Rubicon style wheels, but could never find any with the proper back spacing for 33x12.50s. I finally saw these when ET released them and purchased 5. They gave me the exact look I was going for and ride great!

    Great package

    Love the tires! Great off road. Tolerable on the highway which is better than expected for a mud terrain. I did a lot of research and you will not find a better deal. Only down side is the wheels show damage very easily. They look great, but i don't know if the will hold up to rock crawling.

    Awesome

    These wheels were a direct fit, and due to the offset and backspacing they shift outside the fender about 1.75 inches So you are able to fit larger tires without rubbing. They give a more aggressive look. They look awesome on the Wrangler and I highly recommend these. Originally I was going to have my OEM rims powdercoated but then I saw these and was sold at first sight. These are perfect for the person looking for an all black look.
