Tire selection is a very personal choice based on how you ride the bike, the type of roads you ride, etc.
Some put a car tire on the bike.
I went with Dunlop Elite 3 bias ply in 160/80B16 on my Voyager. Got 16,000 out of the first one.
The Michelin Commander II is a popular tire choice and is rated for up to 20,000 miles. We haven't had anyone on this forum wear out a Commander II yet so we don't know how many miles it will go on these bikes. You have to go slightly larger than stock to put a Michelin Commander II on the bike.
The Excedra Max is still the best tire for the front IMO. People have experienced strange wear patterns and slow speed wobbles with some of the other tires on the front.
Hope this helps a little.
