I have 33/9.50/15s on stock rims with an SOA, BA 10/5 (still haven't got the tcase in yet) and 3.73 axles. It acts just like it did 100,000 miles ago with stock tires and 3.07 gears. Hauls @$$, gets nearly 20 mpg loaded (gets 20 mpg w/o the canopy) and I just used it to move my '70 IH 5 ton in the yard (clutch is nearly fried already so I didn't have much to lose. Pull started the big brute and my MJ is still drivable!)
