My C-10 is my commuter bike.
Spends most of its time on straighter,
high-speed primary roads.
I never get less than 12K miles from a 777.
In fact, it's the only tire I've ever used,
on any bike, that has lasted for two seasons.
By comparison, my "touring" bike goes
through two sets of tires in a season or
roughly 7.5K miles.
