I bought a set of MK2 Protection 2.4 26" tires, and very quickly the sidewall rubber had worn away so much that you can see what looks like a very fuzzy material underneath. This fuzziness picks up dirt and holds it like glue.

The shop warrantied them, but my second pair is doing the same thing.

Has anyone else experienced this? Maybe the replacement set came from the same bad batch? This is turning me off to continental, although I've been happy with the tires in every other way
