Welcome to the forum. There are many good tire/wheel choices these days. What size are you looking for 14-inch or 15-inch. Since you are going with 32's I would suggest going with 15's. A few tires that would be good in the mud are the Gladiator X-Comp, Rage Mohave or BFG T/A KM3.
If we can help you narrow down your choices please let us know.
A 15" wheel with either a 6+1 (+45) or a 5+2 (+38) offset will work good on the wheels. The +38 offset will be slightly wider than the +45 offset. Tires can be a bit up to your preference. I personally like the Pro Armor Crawler XG's. They are fairly light and have great traction in those type of terrains.
