So, if you have a trainer...

Geez, I've never had any of these issues. Some years I've had a different tire on there, but other years, no. Maybe I am not working hard enough?
The only damage we've had was to my DH's shin when he fell backwards off the stability ball and his leg got attacked by the chain ring on my bike on the trainer. He still has the scar, 8 years later.
It was kind of comical to watch that because he could have stood up after falling off the ball, but instead, he flopped over and hit the bike.

Another good reason to use a special "trainer" tire is because the basic tires can get too hot and the tube will burst. It has happened to me 3 times and I finally broke down and bought one. So far, so good.

Interesting to read all of the stories here. Living in Maine, I spend a lot of time on a trainer and have been riding one since the 80's. WE also offer a trainer class in the shop, so lots of trainer time for sure. I always just use an old tire, and at times, have had to swap to another 'old' tire. But have never seen tubes explode, although anything is possible I guess. Have a good indoor season everyone!

I don't use a special tire on the trainer because I still try to ride outside as much as possible with the same bike. If I had to change the tire every time I ride indoors, I would never ride indoors -- I don't have the time or ambition to make the change. But I also have not had any problems.
