I first used these tires on my mountain bike when I wanted to do a road ride with my friends but didn't have a road bike yet. That was years ago. Now I use them on a different bike for commuting. They are great tires and I would recommend them to anyone who wants a light, low rolling resistance, quiet tire for road riding on a mounting bike. I've never had a flat and I weigh in at just under 250 lbs.
