        I installed them with 33x12.50's with no lift since all 4 tires were balled when I got the jeep. An once I install the 4in lift I'm gonna replace them with 35's and 20's but they look great.

        Stylish wheels for not a lot of money

        Picked up a 5th rim for a used TJ I purchased that had these on 32" tires. They look great on a gold Sahara. Extra rim complimented the look, really nice rims.

        I ordered 5 of these, look great in the online picture, but when they arrived they look even better. I will be mounting Patagonia extreme terrain MT tires on them as soon as my balance beads arrive. Thank you Extreme Terrain for the quick service and excellent products. I will post pics of them when installed on my YJ.

        Great Wheels!

        I ordered a set of 5 of these and I couldn’t be happier. They look fantastic and have the backspacing to stop the rubbing I was getting on the stock wheels. I ordered mine as wheels only and took them to a local discount tire shop where I got the a new set of BFG KO2s mounted and installed. Be sure to order lug nuts because they aren’t included. Overall I’m really glad I went with these. They’re a good price and really seem to be a all around great product.

      Are these tires good for highway driving? I drive about 4 hours to college and 4 hours back, and I come home quite often. My current tires have given out on me and cannot make the drive safely anymore? If not these tires, please give recommendations! Thanks!

      • These wheels would be just fine for highway driving. The tire on this wheel looks to be a mud grappler. Being a mud tire, of which can be pretty loud on the highway. We would suggest all season or all terrains if you're doing a lot of highway driving.

      I have 2005 Jeep Wrangler Unlimited Tj. Will this tire and wheel size require a small lift or will it be not rub without one?

      • We would recommend running at least a 2-inch suspension lift with these wheels and tires to have proper clearance and reduce the possibility of rubbing.
