My Cycleops trainer wore through a couple Gatorskins in my early days using it; I didn’t keep an exact track, but I seemed to be getting less time/mileage out of a tire when using it on the trainer AND the road. More recently I keep a spare rear wheel with an old Schwalbe tire that came with my bike. The Schwalbe is going several years now, which is fine because I hated it as a road tire, but it’s done a great job on the trainer.
