ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 25-559 as “25 mm wide, on a 559 mm rim”. If the second number matches your rim, the tire fits.
Sidewall markings for this size are not consistent between brands. The same 25-559 tire is also printed as 26x1.0 — all of these describe the same rim fit.
