I have seen a road tire that has been used on a trainer later fall apart(almost) on the road. The tires in question were Michelin Pro4 service course, a pretty nice riding road tire. They had very little mileage before they went on the trainer. They were on my girlfriend's bike. She would come and ride with me about 50% of the time that I did almost always quitting about 2/3 of the way through my workout. They probably only had 10-15 hours on the trainer. Once we actually started riding outdoors I was riding 3 times as much as she was, but less than halfway through the summer her rear tire started splitting in the middle of the tread. My take is don't ever use really good tires on a trainer
I posted this photo in September of 2021: https://www.bikeforums.net/22229600-post21.html
It's a 28mm GP5000 tire that had around 1500 miles of outdoor use, plus 1500 miles of indoor use on it when I took that photo. I rode that tire on my indoor trainer all last winter (1500-2000 miles) and it's still not worn out. I actually used this same tire on a few outdoor rides earlier this fall and it was fine.
I currently have two pairs of old GP5000 tubed clinchers ready to go for my wheel-on trainer, and I can't seem to wear any of them out. At this rate, I'll probably end up buying a direct drive trainer before I ever get there.
Y'all must put out massively more watts on your trainers than I do.

I use old tires also, I’m still alive and never had a problem with any of them. The one I am using now is a gp4000 and it has a little over 1k trainer miles on it.
