With 10 miles on the clock I put a new set of Kenda HTR 25's on my new 2013 Honda Foreman 500. All I can say is wow these are nice tires. They ride super great, drive straight and have awesome traction. Their not a pure mud tire but do great in normal mud and even in the deeper stuff. They ride as good if not better than the factory shoes and they look WAY better. They run true to size so are a little taller and wider than factory. There a good .5" - .75" taller and about the same amount wider which makes them look bad %#&!@. Unless you want to go alot bigger I would stay factory size with the HTR's. I've had alot of atv tires in the past and these are by far the best for a everyday riding and will handle all sorts of different conditions.
