For tires and length of service you really have to try different tires til you find a set that works for you.
My Vrod always gets about 5500 out of a tire, and rides best with an Avon set on it. Due to the way I ride, the weight I load on the bike and the heat I ride in out here in the dessert.
My FLSTFB rides best with Dunlop American Elite. Gets almost 8500 on a rear tire. Again due to the way I load the bike, drive it and the temperatures I ride in this fits best for my riding on a dollars per mile and performance basis.
5600 on the XG750 tire from Michelin so far... about half shot..... so it may be "the tire" I stay with......
Point is, keep the pressure up on your tires...... don't be afraid to test different tires on the bike... and then stick with the one that works for you.
