Yeah, that's exactly what you do, but turbo trainers rely on the back tyre being under a very large amount of force in order to provide the friction to turn the cylinder. The rubber compound of a normal road tyre isn't hard enough for this kind of usage - any long period of will heat the tyre up to the point of destruction, rubber pellets will roll themselves off your tyre, firing themselves off the back of the trainer, coating the wall/floor in rubber residue, and completely ruining the tyre in the process. Hence why turbo specific tyres exist. Of course, it's much easier to find a spare rear road wheel to swap out, and the wonder of qr makes it a 30 second job. There's a bit more faff involved swapping a rear track wheel out each time you want to ride, which is why I've never bought one.
