ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 28-406 as “28 mm wide, on a 406 mm rim”. If the second number matches your rim, the tire fits.
Sidewall markings for this size are not consistent between brands. The same 28-406 tire is also printed as 20x1.15 — all of these describe the same rim fit.
