Take a look at the Cooper Discoverer AT3 LT.
For an even more aggressive tread there is the Cooper ST/Maxx, which is classified as a commercial traction tire.
You will probably also get recommendations to consider Firestone Destination, General Grabber and other similar tires. All are solid choices for a street jeep.
The key will be to look for AT tires with an LT (light truck) classification, "C" load rating if at all possible. P (passenger), SL (standard load) and XL (extra load) tires would not be a good choice for a jeep, you want a LT tire.
