A 32/115-622 tire mounted on the same 19-millimeter rim. I ordered these because Pirelli makes no mention of the "/115" in the tire size, meaning it's 32×0.15 millimeters taller than 32 millimeters, which equals 36.8 millimeters, which is only a bit less the 37-622 tire, and the clearance when mounted reflects that. The tire also arrived damaged but I doubt it had any impact on the clearance in this test. Perhaps the Schwalbe tire is labeled 37-622 and 700x35c because that's another way of labeling a tire that could otherwise be labeled as 35/106-622, since 37 = 35+(35×0.06). What's fucked from Pirelli is that the next size up for this tire is a 37-622 (700x35c), so Pirelli could've labeled this tire as 36-622 (700x32c), but didn't. Perhaps unlike road tires, urban tires tend to be taller than they are wide, maybe to make room for the puncture protection. I figured the tire casing would become thicker internally instead of externally.
