NEW JEEP OWNER: Wheel spacing and offset questions

I am looking into getting new wheels and tires as well as a lift for my recently purchased an all stock 2007 JKU X. I hope to get 33x12.5r17 tires with a 17x9 wheel -4mm offset. If I get a 2.5 inch suspension lift will I be able to fit this size wheel and tire without spacers? If I need spacers, what size spacers would you recommend and what brand? I am new to the jeep community and this is my first time ever upgrading a vehicle, so I appreciate any help you can give me.

Have you tried this thread? https://www.wranglerforum.com/f27/bac...ize-31911.html Lots of good info there, in fact all the answers to your questions can be found, or the info found from links there.

Also look over this thread for lifting jeeps. https://www.wranglerforum.com/f202/be...jk-298665.html

But I can tell you that the spacers for the wheels have nothing to do with if the lift will work. The lift will deal with helping the 33" part of the tire fit, the offset spacers will deal with the 12.5" width.

I don't know what your stock tire width is, but in order to keep the bigger tires from rubbing when turning, you will need to increase the backspace 1/2 of the difference in the width of the new vs old tires. For example, the new tire setup I want is 2.4 inches wider than the stock setup. 12 inches vs 9.6". So as I understand it so far, I need to get a 1.25" spacer (1.2 to be exact), to move the inside of the tire far enough out where it does not rub.

Try working thru those threads and then ask in them if your answer looks good....

I put 295/70R17 on mine without a lift yet. My wheels have a 4.5 backspace. They only rub when at full lock in reverse. I am putting on my lift next weekend most likely and I don't think I will have any rubbing then. The 33's are about an inch wider than mine. I stick out the fenders about an inch.
