700 x 40C bike tyres
40-622 is the standard ETRTO tyre marking for this nominal size: the first number is the approximate tyre width and the second is the rim’s bead-seat diameter, both in millimetres. Compare current tyre families below, then confirm the exact variant against your bicycle, rim and riding needs.
What 700 x 40C means
A popular gravel size that offers more cushioning and loose-surface control than typical road widths.
Nominal sizes are a starting point, not a guarantee of fitted width. Two tyres carrying the same inch label can use different ETRTO width codes and can measure differently on different rims.

Check the complete fit, not just the name
Match the ETRTO diameter
A marking such as 28-622 gives the nominal width first and the bead-seat diameter second. The diameter must match the rim.
Allow real-world clearance
Actual width varies with the rim and casing. Leave space around the frame, fork, brakes and mudguards, following the bicycle maker’s limits.
Confirm rim and construction
Check permitted rim width, pressure range and whether the exact tyre-and-rim combination supports tubes, tubeless use or hookless rims.
