I've done nearly 2000km on my tyre-drive trainer with my 2nd bike and the same tyre. No problems. I leave that bike on the trainer and, as I would get pretty much no $$ if traded or sold, I don't mind so much if it gets damaged. I wouldn't put my carbon bike on it though...no real reason, just personal preference. Mine is about 12 years old so things have really improved in that time. Mine won't even fit a mtb!!
You can buy specific trainer tyres that are built to withstand the tyre-drive. I don't use one yet, but when mine needs replacing, I will be looking at this. Might be a bit trickier if you take the bike off all the time and road ride.
I got very tired of continually setting the bike up on the trainer when I used it on the road frequently. It was annoying to get everything right with the correct tension on the tyre and I found I would put off doing it because of this reason. Since having a dedicated bike, I've found it much better.
I also have a recumbent exercise bike (does this put me in some sort of elite 'bent group

) that feels like it uses different muscles, but I prefer the trainer.
I enjoy riding mine and find I can target specific HR zones, or do sprint/easy/sprint stuff without worring about terrain or cars or pedestrians etc.
Some bike shops have trainer sessions - it is worth inquiring as you may try it and hate it!!
Moo...
