50-584 Bicycle Tires (650x50B)

ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 50-584 as “50 mm wide, on a 584 mm rim”. If the second number matches your rim, the tire fits.

Sidewall markings for this size are not consistent between brands. The same 50-584 tire is also printed as 27.5, 27.5x1.95, 27.5x2.0, 27.5x2.00, 650Bx50 — all of these describe the same rim fit.
