Sources and notes
- Conversion: 1 psi = 6.894 757 kPa and 1 bar = 100 kPa, from the NIST Guide to the SI (SP 811), Appendix B.8: Factors for Units Listed Alphabetically (checked 13 Nov 2026). NIST prints the bar factor as exact; the psi factor is NIST's rounded 7-digit figure. Results are rounded: psi to 0.1, bar to 0.01, kPa to whole numbers.
- Hookless max (More options): the ETRTO limit for your tire width, as Schwalbe prints it on The optimal rim for Schwalbe tubeless racing bike tires (checked 17 Oct 2026): 18–24 mm 5.5 bar, 25–29 mm 5 bar, 30–34 mm 4.5 bar, 35–39 mm 4 bar, 40–44 mm 3.5 bar, 45–54 mm 3 bar, 55–64 mm 2.5 bar, 65–74 mm 2 bar, 75–84 mm 1.5 bar. It covers 18 to 84 mm tires. Your tire and rim maker can set a lower limit, and the lowest figure applies. Psi is our conversion of the bar figure.
- Only units: the tool converts units. It doesn't say what pressure is right for your tire; for that, use the tire pressure calculator and your tire's printed limits.
