I just got my new bike (Kona Dew Deluxe) and it's got 700x37c tires on it. As I lack an accurate measuring device, I can't find out for myself. Anyone have a computer that's had to get this tire circumference manually? If so, it'd be great if you could post the numbers you got.

He has several pages on cycle computer calibaration and calibration charts for different computers and tires. http://www.sheldonbrown.com/cyclecom...libration.html

Depends on the tire. Some mfg's list the circumferences on the packaging. But simple measurement is the most accurate.
