If you never go off road, I wold go with Firestone Destination LE2, but hey, it is a Jeep so why get HWY only tires ? For an AT tire, I suggest the Cooper Discoverer AT3. I previously had Firestone Destination AT, GY Fortera tripletread, and the stock GY, and the Coopers are easily the best, also the cheapest of all 4 I've used. Firestones AT are 2nd, but Coopers are much smoother riding on the HWY and better over bumps, potholes, etc, quieter, great off road, and have excellent snow traction.
