Not sure what you mean by adventure series tires?
The standard tires are Goodyear Wrangler RTS, and from my experience they are ok on the roads, but not all that great off-road (actually, terrible from my experiences in the Jeep).
The off-road suspension package adds Bridgestone Dueler A/T tires, and from talking with people who have had these tires, and off-roaded them, they are a very good mix of on road/off-road tire. In fact, some have told me from their experiences that they are as good as BGF AT tires off-road. (Don't burn me BFG lovers, I'm only passing on information from people I trust.)
I have no personal experience with either of these tires (except what I have driven on my Hummer), but I do know that when replacement time comes, I will purchase Yokohama Geolander HT Plus, if they have this size.

As others have already stated, getting a good balance between what is require for pavement versus sand/mud/gravel, etc., is tough.
