The Conti trainer tires work and work well. They are very quiet, provide consistent resistance as the rubber doesn't get soft when it heats up and they don't wear at all (at least for me it didn't wear). I used one on my Computrainer all winter with good results. Having a dedicated trainer tire also keeps the tire/roller interface free of contamination which will give you a more accurate reading on the CT. Saying all that, you are not to ride them on the road.
