Re: want to lift my jeep.
Huge 4X4 and inexpensive will probably not ever go together. Considering what you are driving (a JK not a TJ, CJ, ect) the average upgrade seems to be a 35 inch tire. My tires and cheap rims (knew they would get destroyed off roading) cost just over $3000. 35 allowed me to go with a small lift which was $800. That is just parts not labor because I did my own work. You said you wanted huge 4X4 and 4 inches of lift. I would assume that 37+ inches of tire. Most guys I know running a tire that size spent close to $5000. A quality lift with 4 inches of lift is going to run about $2000. Rock crawler, AEV, Old Man Emu to name a few. But once again you didn't really give any information except "BIG 4X4". If that's what you want plan on spending $7k to $8k. That's just lift and tires.
Now let's assume $ is a problem. Start with tires. I wouldn't go over 35 because the tires get so big they wear things out that much quicker and then you need maintenance $$. I would aim for a 15 in rim. I run this (15 rim 35 tire) and get asked all the time if they are 37's I have been told by guys running 37's my tires look bigger than theirs. It is kinda an optical illusion. The 37 guys usually run an 18 rim. So that gives them 19 inch sidewall on their tire. The 18 rim/19sidewall looks equal. But next to my 15rim/20sidewall it gives an appearance of a larger tire.
