i had my conti-touring (rears only) replaced at 16,500 miles...i was sliding through too many turn in the wet weather of south fla...the front are great and still have like 6,000 - 8,000 miles left on them. My new tires were the Conti-sport 2's (rear) and they are an awesome tire. they have 8,000 miles on them and they don't look the slightest bit worn.
