Currently have 8400 mi. on the stock 021's. Back still has some life left on it, the front, hopefully enough to get through the weekend. This is the first bike that I have owned that the front has worn out first. I'll have around 8700 on them when I drop it off at the dealer on monday to get a set of PR3's installed. Going to have them install the 90 degree valve stems also.
use any sport/tour tire from major tire company .You cant go wrong with any of them.
Metler,bridgestone, pirreli,Avon Dunlop They're all good.
Some may wear a little better than others but if you are a smooth rider that lets your tires warm up before railing you'll never have problems sticking to the road.They stick like poop to a white blanket.
Im disappointed in my shinko raven. I installed it at 6500 miles and at 10200 its on the wear bars. I wil be lucky to get 4000 miles out of it. It sticks great but that is not sport touring mileage.
