1500 miles what are you doing??? You running 20 psi or something. I have never gotten less then 4500 miles out of my stock tires on any of my 1000s. Anyone who has ridden with me can tell you I don't baby the bikes on acceleration. I am at 5000 miles on my 06 1k with 2-3 short burnouts (2 in work parking lot to warm tire for race practice launch), a Slab trip to South of Macon, GA and back, then week after a ride down to Nashville, TN and back. I have only done one trip to twisties with it so far. I still got a few hundred miles, but will be doing a tire change maybe this week or weekend.
