If you are avoiding a lift and don't want to remove the crash bars... 285/70R17 (33s). 295/70R17 (34s) should also work for probably 90%+ of the tires on the market, but it's a little close and the random size variations between manufacturers might bite you—especially if you max out suspension while turning.
Anything more than that and you are probably looking at removing the crash bars and adding a lift. Limiting factor will be the width of the wheel. Those steelies are 7.5-inch wide, and vast majority of 35s on the market will require 8-inch or 8.5-inch wide wheels. You can still absolutely mount 35s, but it'll be one of the relatively rare "pizza cutter" sizes due to the width limitation: 35x10.50R17, 35x11.50R17, 255/85R17, etc.
My favorite of the pizza cutters is the 255/85R17 Mickey Thompson Baja Boss A/T.
