Love them

Great looking wheels especially for the price. They stick out a couple inches farther than the stock rims did. Worked perfectly for me cause I had some rubbing on tight turns anyway. I do see some bigger fender flares in my future tho. Very quick shipping. I ordered them on the evening of the Dec 25th and received them on the 27th. If you like the look in the picture you will love them when you get them. Only draw back i can see is they are made in China

Mammoth wheel

Quality of wheel is high; like the look. Don't like the Mickey Thompson tires, though. Too, noisy, too much steering feedback on pavement. My fault though; purchased too aggressive of a tire for my needs.

My Upgrades

Well, after finding this site, I have purchased many items in order to upgrade my 2002 Wrangler. During the purchase frenzy, I bought a Rough Country Lift Kit from here too. Well as we all know once a lift kit is bought.... New tires and wheels have to be bought too. I am very pleased with my purchases, included my new beadlocks and MT 33's. NICE, all getting installed this week, pictures to come.

Review from Mammoth Boulder Beadlock Style Black Wheel - 15x8 Wheel - and Mickey Thompson Baja MTZ 35X12.50R15 (87-06 Wrangler YJ & TJ)

Mammoth/MT combo

I previously had 33" mud claws on my TJ, they were great tires but very loud on road. Switched things up and got the 35" Mickey thompson and mammoth combo and love the decision. The tread cleans out well after being in the mud and they didn't slip one time, plenty of grip and not too loud on the street. Great tire and the wheels look sharp!

Wow!

This was an awesome purchase! The tires and wheels were beautiful! Popped them right on and drove off. If you order a set like this MAKE SURE YOU'RE NOT HOME WHEN THE UPS DRIVER DELIVERS THEM. My driver was not real happy. I ordered five mounted tires and they are HEAVEEEEEE!!!!
