Yeah, terrain is going to matter a lot. I run though heavy mud/heavy rain/sand and occasionally snow/ice. I run Falken Wildpeaks and love them. Sometimes a little bit of slip from a stoplight in the rain, but only if I gas it. My father runs Cooper Discovery AT3s XLTs on his 89 YJ. They're insane in the mud/dirt. Loud on the highway. I have ran about 30k miles on my Wildpeaks, probably get 45k by the time they're toast - but I've driven them hard for the past 30k. Pretty quiet on the highway, relatively speaking. BFGs have always been the go-to, I think Wildpeaks are a great rival (and less expensive). I'd recommend them, and of course Cooper Discoverers are a popular choice as well (made in the USA too)
