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 factory spare may be too small to be used. And besides a big meaty spare looks intimidating on the back of your Wrangler.

Matte Black Mammoth 4x4 Boulder Beadlock. Upgrade your JK or JKU with the Mammoth 4x4 Boulder Beadlock Style Black Wheel from ExtremeTerrain. This Mammoth 4x4 wheel features classic five spoke styling with an aggressive spin made to take on the trail. Specific to your Wrangler, it features a hub centric design to provide the reliability you need on the highway or off the paved path for a bold look no matter where your tire tracks end. Completed in a durable matte black powder coat for a rugged off road appearance, this Mammoth 4x4 features a polished lip with simulated bead locks to create a bold off road appearance. It comes complete with a matching Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

LT315/75R16 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.

      I would like to run 33" by 12.5" tires. can I do this with 16" rims? Is there any benefit between 16 / 17 with the same total height. (I like the look of smaller rim w/larger tire)

      • If your looking to run a 33x12.5R16 you would want to run a 305/70R16 tire. The benefit for running a larger tire is when airing them down for heavy off roading, and it can provide a softer ride feel on roads.

      the rims on my 2017 jeep wrangler are 16 x7 if i change rims to 16x8 will i need new tires

      • You can visit the tire manufacturer's website to check what wheel size is appropriate for the tires you currently have.

          Wheels look “sick”

          Since putting on the 16” wheel with 315 Nitto Trail grapplers I get lots of good comments. Recently ran Drummond Island, MI and the combination tire to wheel performed fantastically.

          Excellent wheels. I’ve bought the “big brand names” in the past and these Mammoth’s live up to any other. Plus you cannot beat the price, all 4 under 500. It’s like a bogo. They look great on too!! As long as I have my Jeep these wheels will be on it.

          These wheels look great ! The guy at the tire shop was really impressed with the new look of my JK. The wife was a little unsure of the style (she prefers shiny polished wheels) but when she saw them on the Jeep she said it looked tough.

          Bought the Wrangler with after market wheels, Plastic Caps for centers, made a rattle on bumps that made me grit my teeth. New wheels look great and I am not gritting my theeth on Bumpy roads. Should have purchased these Mammoth Wheels sooner.

          Great product

          The tires are great. Road noise is kept to a minimum with this style while maintaining an aggressive look. Comfortable ride with no complaints. Only issue was during purchase four tires arrived instead of five, the issue was on the shipping and not on Extreme Terrain.
