Another comment on them--compared to any other tire I've tried they seem to have the most consistent wear when they are getting to the end. They were going down very predictably, compared to some tires that just are gone before you expect it. I would have liked to run them to the threads to see what happened, but traction will be a serious issue when I finally pull my bike out in April to ride and the roads have been sanded all winter.
When Avon ran their $50 rebate I thought they might end up dropping the price, but they remain a pretty pricy tire, which is why I didn't get another set.
