The webbing on the outside of my almost brand new conti's is falling off! Is this a cosmetic issue or a hazard? I emailed conti & got no response (grrr...)

These are the 4 season, expensive ($60+) tires. I've noticed my last few tires had problems with some of the threads next to the rim coming loose - but this is a first.

Naturally, this is the rear tire. It looks OK and I've noticed that the conti 4000's don't even have this webbing. I hate to blow out in the middle of nowhere.

Help!
