33 with 4.11:1 gears will work great. IF your on the rocks all the time 4.56:1 gears are a good idea. Normal tire size for a 33 is
33x10.5r15
33x12.5r15
285/75 r16
Only 1 company makes a 265/80 r16

33" tires with 3.50 gears will work without issues on the street but no fun off road. The 4.11 is a lot better and will be close to stock settings. If you are planing to fit bigger tires such as 35" falken tires in the future, then put 4.56 now and be done with it.

really wish they had 9.50s in the 15 or 16 these daze. I think the only way to get now is those real expensive 'antique' tire cos, specalties. I had a pretty standard 9.50x15x33 for decades (BFGs AT... was it TA KO? something like that)...My 70/7 is not hi (1 inch BL, 2 inch SL) and they fit (even with a 1/4 cord of wood). I want to go on rd a lill more now, get those $800 softer springs & have Qs abt it. The 'pie cutters' were pretty nice in the sno too.
