I ordered a new set of tires direct from Schwalbe last week. I got Marathon Supremes in 700x32. They arrived yesterday and I got them mounted, but they don't look anywhere near 32mm to me. They look more like 700x25. They are mounted on 15mm rims.
Is it possible they sent me a smaller size, or am I just a poor judge of tire width? I wish I had come calipers to measure them.
