      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.

      15x8 Mammoth Boulder Black Wheels. Upgrade your TJ or YJ with the Mammoth 4x4 Boulder Black Wheel from ExtremeTerrain. This Mammoth 4x4 wheel features classic Wrangler 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.

      33X12.50R15 Dick Cepek Fun Country Tires. This Dick Cepek Fun Country Tire is designed to accommodate the best of both worlds, whether you drive your Wrangler strictly on the street or enjoy off-road adventures on a regular basis. The unique aggressive design incorporates wide alternating tread grooves for increased off-road traction and the tire has a computer-optimized pitch sequence in the tread that gives you a quieter ride on the street. This 33X12.50R15 black-wall tire is made to be installed on 15-inch wheels that are 8.5" to 11" wide.

      Application. These 15x8 Mammoth Boulder Black Wheels and 33X12.50R15 Dick Cepek Fun Country Tires fit 1987-2006 YJ and TJ Jeep Wranglers.

        4 2005 Wrangler - Mburke

        Wheel and tire

        It was a good purchase, but when they arrived at my house, all the weights were on poorly, half of them were off, I was very disappointed with the work they put into it, but the quality of the tires and rims are very nice,

        5 2004 Wrangler - RussellE

        Love the new wheels and tires!

        Bought these after putting the 3.25 RC lift on my 04 TJ. Really made a huge difference in the look of the vehicle. Fit was perfect, no rubbing and installation was a breeze with the mount and balance already complete. You do have to purchase lug nuts as those are not included. I guess you could use your old ones, but I wanted a matching black set. Road noise isn't as bad as I thought with the Dick Cepek tires. Has aggressive tread, but not overbearing and the black mammoth wheels look great. Very pleased so far. Just need an alignment and I feel like the ride will be much smoother.

      3 Top Rated Questions

      Does this package come with black lug nuts or do I have to you the old chrome ones that I have?

      • The wheel and tire kits do not include lug nuts, you can use the factory lugs with these wheels or purchase a new set to match with them.

      Has anyone installed these on stock lift ? Or installed on a 2 inch lift

      • In order to avoid rubbing or clearance issues we recommend installing these with a 2 or 3 inch lift.

      Would I have enough room to go off roading with a 2.5 inch lift on my 2000 TJ? I don't do it often but I don't know if there would be enough room to run 33 tires.

      • You would need to add a 1" body lift to your lift and possibly need to do some fender trimming or aftermarket high clearance fenders
