I have a 2007 Sahara. I have owned two Cj's about 8 years ago just out of high school. I ran 33" MT's on both for tires and would really like to invest in some for my Sahara. The question I can not answer myself is, do I need a lift to fit 33's or do I have room? If anyone could let me know I would appreciate it. I have spec'd out some Cooper STT LTs which are very reasonably priced and the size I was thinking of getting are 285/75 16...right now I have the stock 255/70 18.
You have room for 33s in the JK in stock form, the JK Rubicons come with 32s stock. If I were you I would skip 16s the reason being is the tires are usually only D and E rated which are terrible for a Jeep, the best size you can get for a JK is a 17" tire, they are relatively cheap and come in C load range. 17s are becoming the new 15" tire size, there are more and more options in 17" everyday and less and less 15" sizes.
