ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 40-559 as “40 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 40-559 tire is also printed as 26x1.5, 26x1.60, 50-559 — all of these describe the same rim fit.
