how old was the tire, how many kms or miles on it, photo?
all that doesnt change the fact that its a drag for you.

My experience with various Schwalbe tires, and really all good to great quality tires of any brand, is that something like this is extremely rare.
I put one of my super old supremes on one of my bikes recently just to not use some of my newer tires and have a faster nicer tire on the bike, and it slowly developed a slight bead issue, but frankly, that tire is at least 9 years old and has multiple fully loaded tours on it over all kinds of road surfaces in many many countries, so not a surprise to me given the mileage on the tire.
The Supremes sidewall characteristics is what gives that tire such a cushy, efficient ride quality. A real example of Supple life, but one has to keep the thin, flexible sidewall in mind--just like with any higher end supple tire, Rene Hearse or whatever.

touch wood though, I still have a pair of narrower Supremes 1.6 inch that I only have on for road trips on good roads.
