I have a magnetic trainer. It has rim drive instead of friction drive so it does NOT wear down the tire. And it isn't too terrible loud. Compared to the friction trainers in use at my spinning class, it's downright quiet! Since Christmas, I have been on it every stinking day! It's a real love/hate relationship. They may seem pricey, but if you can't get outside and ride, I think any trainer is well worth it! BikerHen
