I have been riding Conti 4 Season tires (700 x 23) for about 1800 miles. Tires, especially rear, are starting to look worn although other than some small nicks on the sidewall I've had no problems.. I do about 120+ miles per week (ride, not race) and am planning a century this Sunday, another late August, and a 5 day 300 mile ride in Oct.
Any suggestions on when to replace them and with what?
