It also really depends on the type of tire you buy. If you buy more expensive softer stickier tires they do not last anywhere near as long as harder tires.
I have pilot powers on my bike and 3k is the most I can get out of them. However, I do a lot of twisties, so I figure I should get the best tire I can for my money; it's worth it for that extra edge of traction once the tire is warmed up.
Pilot roads probably would last another 1000 miles.
Or I could just go with a car tire, and it would last the life expectancy of the bike, which would probably be longer than mine.
