My wife and I only use them on our touring bikes but 32s. Thousands of miles on both bikes and can only recall one flat on each bike. Her’s was on an older tire and a somewhat typical flat but can’t remember what it was. Mine was while doing a day ride during a tour and a piece of metal lodged perpendicular to the rim piercing the tire on both sides. I never saw the road debris and if I was not on the bike when it happened, I would have suspected the tire was vandalized. I tell this story because this flat was so unique and unlikely to happen again.
My story about Schwalbes is typical among touring cyclists. I see no reason 25s would be different but that would be my only question about them. And if you can’t find more information about that size being more prone to flats, I would buy them and the wine at the same time.
