Sources and notes
Each source's own chart, quoted. Not our advice, not merged, and not tested by us. Where they differ, both are shown.
Ranges are each source's, read from their own pages and charts on 17 Oct 2026. The ETRTO table rows are tire-width bands and its columns are rim widths; a half-millimetre rim shows both neighbouring columns. Always follow the rim's and the tire's own limits, and the lower one where they differ. Left out: Hunt: Its help centre publishes measured fitted widths per wheelset and tyre (Fitted Tyre Width Guide), not a tire range by internal rim width. Read 17 Oct. Zipp (as a range): Zipp says minimum width is in its Hookless Tire Compatibility Chart and “is based on the wheel model and tire brand”, so there is no range by internal width. Its 25 mm statement is shown as a note. ISO Table 7 (Bicycling): A magazine's image of the ISO table. The same ETRTO 2024 table is published directly by Schwalbe and Continental, so we use theirs. Its minimums match theirs. ETRTO 2020 pairings (BikeRadar): An older table seen only as a magazine reprint (21 mm: 29 to 34 mm). Superseded by the 2024 table as the tire makers publish it. Mavic: Its ETRTO/ISO chart PDF sets a maximum pressure in each tire/rim cell. Not added this run; it needs a separate careful read. ENVE mountain wheels: Tire ranges given in inches for MTB rims (25 to 85 mm). Out of scope for a road and gravel tool.
