I also use the Vittoria Zaffiro Pro Home Trainer tire, but I have had two of those develop a weak point in the tread and “bubble up”. The weak point develops suddenly and you start hearing a bump-bump-bump sound. The first time I heard it, I didn’t stop riding. The tire blew with an incredibly loud noise. I am now on my third Vittoria. I also managed to ruin a Michelin road tire pretty quickly, so I am sticking with the trainer tires. They seem to last about 3500 miles on Zwift.
