Recommended 5th Wheel Upgrade. When increasing the rolling diameter of your Jeep Wranglers tires it is recommended to upgrade your spare tire at the same time as the stock spare may be too small to be used. And besides a big meaty spare looks intimidating on the back of your Wrangler.

It comes complete with a matching Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

33X10.50R15LT BF Goodrich Mud-Terrain T/A KM2. BF Goodrich Mud Terrain T/A KM2 is the end all in off road capability. You'll never doubt traction on the trail with this tire's aggressive side wall lugs and self cleaning dual compound tread design. Your Wrangler will conquer climbs and pits and any obstacle with BF Goodrich's linear flex zone which allows this tire to conform to obstacles and grab the trail during aired-down crawling and driving. TriGard 3-ply construction and a chip resistant compound protect this tire from any trail hazards you run into, including cuts from rocks or boulders.

    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.

    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!

    Great looking wheels!

    Classic 5 spoke design with a nice simulated bead lock. Look alot better in person than in the picture. I ordered them on a Saturday and they were delivered by the following Wednesday. If I had to think of a complaint it would be that there is no back spacing options on this wheel. As far as I saw you could only get 3.75" of back spacing. Not and issue for me running 33" tires but if you go bigger you will probably need wheel spacers.
