| Metric / French | 650x30B |
| Imperial (calculated) | 27.5 x 1.18 |

| Rim bead seat diameter | 584 mm |
| Common wheel name | 650B / 27.5-inch |
ETRTO is the only tire size standard that describes a real, measurable dimension, which is why it is the one worth trusting. Read 30-584 as “30 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 30-584 tire is also printed as 27.5, 650Bx30 — all of these describe the same rim fit.
