So, you're going for the mall crawler look?
If you want big wheels and tires, you're gonna need at least a
3" lift = 35" tires
4" lift = 37" tires
6" lift = 37"+ tires
Most people would be offended by what I'm about to say, but here it goes. You can also add a spacer for a body lift if you want a little extra clearance.
If you wanna pay dealership labor prices, which are ridiculously overpriced, go ahead. You can install the lift yourself, if you're mechanically inclined. You can have wheels and tires mounted and delivered to your home so all you have to do is put them on yourself. If you're afraid of getting dirty, go to your local 4wheel shop.
Do you want your wrangler to sit and look pretty or work off-road? I doubt Kevin's vehicle will ever see grass or dirt.
Cost will also be a barrier for those big meats. Off-road tires are no where near cheap.
Either way you choose to go, think about what the purpose of the vehicle is going to be before you drop thousands of $$$$.
