Are they cut or uncut? What kind of tracks do you run on? Sandy, Maybe the Bigger ones. Good Biting tracks probably the smaller ones. You see you can't just get on and ask a simple question and expect a simple answer. 200 HP is not a lot HP to be running 20.8 tires especially when you do not state whether or not you are pulling an open class tractor or a MPH tractor. Not trying to be rude but there is a lot of factors that decide the answer to your question that have not been stated and that the others are not even taking in to consideration. In other words talk to people who you think will help you that you know personally but here is an example of what you get when you don't know, answer after answer that don't tell you anything. Experience is the best educator unless you are blessed with friends like I have had, Ken Foland, Art Forrest, and Randy Babbitt and others but even then you have to watch out, they are ornery you know.
