Hello I'm fairly new to this site. With in the last year I have become a jeep owner again, yes! I have purchased a 2004 Rubicon (a real cream puff) I will be replacing the original tires soon and am looking for advice. I have been contemplating the currie 4" lift kit but reality is I'm not sure I need that type of performance. I recently moved the Jeep to AZ and will be exploring the Southwest. What is the largest size tire I can put under my jeep without going through the expense of installing a lift kit? I am running a 2004 Rubicon TJ with stock 16" rims.
