23-559 Bicycle Tires (26x7/8)

ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 23-559 as “23 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 23-559 tire is also printed as 26x0.90 — all of these describe the same rim fit.
