I have basically the same Jeep, only mines better looking.
I've asked and asked and debated on wheel/tire combinations for a month. I've Read about other mods on here, like bumpers, roof racks, etc. all of which add significant weight.
So, Here's my suggestion. For tires I've read good things about the BFG's and that you can go up to 285/70 without a lift. This is a consensus of quite a few old timers on here.
Now, consider this. What else do you plan to do to your Jeep? Bumpers? Racks? If you plan on getting aftermarket bumpers, you should upgrade your suspension. Just upgrading your springs and shocks will add 2" to your vehicle. (It's also recommended to change your track bar and lower control arm bolts as the stock bolts are under sized.)
New tires all around will cost you more for the parts to upgrade your suspension and if done first will give you a better reference point for what tires/wheels you want to get.
