I agree with the above comments. Just to pile on a little.
I happen to agree with you that a 4 inch suspension lift and 33 inch tires is more than adequate to get started. And I also did not want to diminish the highway driving qualities of my jeep. I wanted to enjoy driving it every day. I have a 3.5 inch spring kit and a 1 inch body lift. I have enough room to run 35 inch tires, but the additional expenses required to keep the jeep safe and mechanically dependable convinced me that 33 inch tires would make me happier.
I continue to learn about ways I could have modified my jeep. But I still believe you have to spend enough to get some good products and modify some key mechanics, if you want to have a problem free experience.
I usually just drive around town, but I don't find it uncomfortable to drive all day on the interstate. I can cruise 70-75 mph with one hand on the wheel. Mud tires do create a road roar, and it's more comfortable with my hard top and roll up windows when driving long distances at speed.
I find myself reading these internet jeep forums quite often. There are several like this one that are good sources of information. (Just in case you hadn't looked around yet on the internet.) Many will agree that one of the smartest things you can do is take a few days or weeks and read various conversations like this one you've started. Sometimes you'll be surprised to learn something in a topic that you normally wouldn't think would interest you. I can think of several jeep ideas that I was advised against that consequently turned out better for me.
When a jeep owner asks a question, it's sometimes difficult to determine how much they already know. What I usually do is look at the date the jeep owner joined the forum and how many times they've posted a comment. I might check their personal jeep profile to see if they include a picture or other information. None of which really proves anything, but it helps when someone wants to give advice. You recently joined and you ask a fairly basic question. So I'll guess you might appreciate a thorough comment. But if you already know some of this stuff, maybe someone else reading will find it useful. I like to read a complete answer but most fellas are wise enough keep it short. I don't often say anything because I feel compelled to say too much....
You have a '03 rubicon package TJ. The rubicon was first available in '03 and it continued until the end of the TJ in '06. The package continues in the redesigned wrangler starting in '07. In addition you have a special edition "tomb raider" package that included some dress up items. Jeep has been famous over the years for doing special packages. Way back they got a lot of mileage out of using Levi's Jeans fabric as seat upholstery on a special edition classic jeep. Anyway, the "rubicon" model is well regarded generally for the extras you get.
It's not easy to see your profile picture, but it looks like someone replaced the original alloy wheels that came with the jeep. The original wheels were popularly called "moabs". They would have been 16 inch diameter by 8 inches wide. I believe they had about 4 inches of backspace that kept the original tire tucked under the plastic fender flares. The standard size on wranglers up till then was a 15 inch wheel in various styles. My guess is that the increasing popularity of disc brakes with their larger rotors and calipers dictates that there be room inside the wheel that older tech drum brakes didn't require. There may be other reasons for the trend to go to larger diameter wheels, but many traditional fellas will advise you stay with a 15 or 16 inch wheel for 33's.
The new style wranglers come factory with 17 and sometimes 18 inch alloy wheels, so I'm behind the times. I'm slow to warm up to changes. I don't care for the look of low profile tires and large diameter wheels, especially on a truck. Maybe you could convince your wife to reconsider the "rock stars ". Maybe someone else will speak up with other reasons to help you decide.
I'm at work....I gotta stop....
