It's amusing that some folks don't seem to notice the difference between trainers and rollers. Some trainers seem to need a trainer-specific tire, judging by the anecdotes on here. However rollers most definitely do not. I've been using one of my bikes for rollers exclusively for a while. The odometer says 3300 miles since the last battery change. Maybe 8000 miles since I stopped riding it outside? Very little tire wear and these rollers have resistance, so I do work hard on them sometimes. Interestingly, I've had a couple punctures from odd bits of debris on the rollers - they're out in my shop. I've gone through I think 3 tubes due to valve failure because I pump every time I ride the rollers so that my intensity will always be the same at the same speed. I had to change out a front tire because the casing cracked due to age, even though it showed no wear.
