Initially BFG KO2's in 265/70/17 (31.5")
Then on to Milestar Patagonia 285/70/17 (honest 33" tire)
Just ordered Kenda Klever KR601 R/T - 35*/10.5/17 (narrow 34" when mounted)
Running a 2" AEV lift on the JKU. Looking to see how this R/T runs as a DD and trails. Snowed here finally last night but the tires wont be in until Monday.
I'm running the 37x12.5r17 STT pros on mine. So far so good. I basically put them on before a 1600 km road trip to go wheel in Rausch Creek for a few days and go meet up with some guys I deal with through work. have put a few trips on them now and they seem to be wearing well but i keep them at a fairly low pressure to get even wear with the slightly stiffer sidewall ( on a relatively light Jeep). i run 6-8 PSI offroad and roughly 27 on road. Not sure what your running but with a 20" rim it must be bigger than mine LOL.I'll be jumping to 37x12.5r20 Cooper STT's before next winter most likely.
I hate 20" wheels. Would rather stick with 18's. But E rated 3750# tires might be better if I go the slide in camper route.
