Hello-

Recently I had a pair of Panaracer Pasela TG tires replaced under warranty because of cracking sidewalls. Panaracer generously replaced them with a set of Ribmos and now after only a few months cracks on the sidewalls have formed on these as well. I don't have a lot of experience with road tires but I have never had sidewalls cracking on any bike I have had before.

Is this a common occurrence? Just looking for some experience with this as far as safety what others have done.

Thanks!
