Raleigh One Tyre Size: Read 56-584 Alongside the 27.5 Label

Raleigh One tyre size is recorded in two forms: a 27.5 wheel-size label and a Raleigh ONE 56-584 tyre entry. Those are not competing measurements of one object. Reading the complete tyre designation gives a more precise starting point than carrying only “27.5” into a replacement enquiry.

Decode the Raleigh One tyre size notation

Schwalbe's size guide explains the ETRTO format as tyre width in millimetres followed by the tyre's inner diameter in millimetres. Applying that notation to the manufacturer's 56-584 entry gives a nominal 56 mm width and 584 mm inner diameter. Neither number describes the Raleigh frame size.

An inch designation expresses an approximate outside diameter. Its purpose differs from the inner-diameter figure in the ETRTO marking. Do not compare 27.5 directly with 584 as though one manufacturer had accidentally changed units while measuring the same boundary.

Separate size identification from replacement approval

The saved Raleigh table leaves its rim and wheelset details unfilled. The tyre code cannot supply that missing rim information. In its general dimensions guidance, Schwalbe says the tyre's inner diameter must match the rim shoulder diameter, and tyre width must also match the inner rim width.

These are useful questions for a supplier, rather than approval for every tyre marked 584. A matching diameter does not settle width, the actual rim's requirements or clearance on the individual bicycle. The generic tyre guide does not specify a wider Raleigh tyre, a pressure setting or a tubeless conversion.

Take both the catalogue entry and the actual marking

The Raleigh One - Smart Bike — Sage Grey listing identifies the local One model. Keep that identity with the saved 56-584 description. For a bicycle already in use, also record the complete marking on its fitted tyre; a later replacement may differ from the catalogue entry.

Ask for the missing wheel and rim identification before selecting an alternative. The Raleigh reference topic provides model context, and the family introduction explains why a familiar badge alone cannot identify every Raleigh wheel.

FAQ: reading the two tyre labels

Does 56-584 describe a 584 mm tyre width?

No. In the ETRTO notation, 56 is the nominal width.

Is the 27.5 label an exact rim-width measurement?

No. The source uses it as a wheel-size label.

Does a matching inner diameter approve any replacement width?

No. Width and the actual rim and bicycle requirements still need verification.
