I have a used but in great shape Challenge Fango 32mm tire. I used this for one season of training (once a week maybe) and then when I pulled it off, I damaged the base tape so I had it repaired at TireAlert.com and they put on new base tape. The tire has aqua seal on it but it got pulled up in a few spots but the casing/tread isn't damaged.
