We had Supremes on our tandem for about 3 seasons. No punctures in about 4,000 miles. Replaced them with Marathon Racers because Supremes no longer made in 20"/406 which is our front wheel size. So far so good after one season/1400 miles. No punctures.Racers on my commuter 'bent, too. 3 punctures in about 3 years. Very little winter riding on either bike and especially avoid ice/snow.
As has been said by others, Racers are not racing tires.
