I recently switched from 33" Interco TrXus MTs to 35" BFG AT/KOs and I have not yet regeared my Jeep. With 4.10 gears, and 4:1 low, the Jeep does real well on the trail and on the street. I plan to eventually gear to 4.88s, but for the meantime, I have been happy with my AT/KOs and their overall performance.
I'm not easy on my tires, but these have held up to my most recent 2 day Baja trail run. Here are a few pics where my AT/KOs held up with the KM2s in the mud and on the rocks. I was very impressed with their performance on the trail and their quiet manners on the street.
Crossing this mud/river crossing, I was sure that I would get stuck. I drove right through without breaking much traction (rear locker in use)
This is Russ driving through with his KM2s - mud/water over his hubs
The entire group was running either BFG AT/KOs or KM2s
We traveled a 2 day trail that claimed this Interco SSR
Lateral grip was very good with my AT/KOs - something I was concerned about on this trail
