        I have a 2005 Unlimited with my factory rims I can not use 33x12.5x15 because the rear rub. Will these space it out enough so that I can upgrade my tires also?

        • Hello, yes, this wheel will space out enough so you will not have any issues with rubbing.

        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.

            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.

            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.

            Great looking tires!

            Arrived intact with no visible bruises from shipment. Wheels look awesome on my 94 YJ! Great price for 5 tires/wheels. I had 31x10.5 before, added 4.5 inch lift and these bad boys and get complimented/looked at all around town. Love the look and the backspacing/offset of these are perfect for giving it a beefy look without going to 35s. I will caution that the 5th spare won’t likely fit on your original hardware.

            4 1999 Wrangler - DavidC


            The wheels came pretty quickly, even coming from two locations. Great wheel for the price, looks nice, open design easy to clean. Did not buy as a wheel/tire set as already had new studded snows. One wheel took alot of weight to balance, 8.75 , which is alot on a 15 inch rim. It did need alot of weight to balance, possibly a manufacture tolerance issue, I'm sure I could have gotten a different rim if I wanted. Over all, happy with the wheels and would go with the same wheels again. Not paying the high prices that most wheels cost, especially with the road salts that are used in the winter.

            Wheel and Tire package

            Super happy with both wheels and tires, first two arrived on a sat then received the other two the following mon. Installed myself, only took about an hour or so by myself to get them all on. This is my daily driver and I live in the PNW where we get a lot of rain and these tires perform awesome on the freeway. Tires and wheels are balanced perfect and love the way the set up looks.
