27.5 x 2.6 bike tyres

What 27.5 x 2.6 means

584 mm bead-seat diameter; nominal width varies27.5-inch MTB and gravel3 catalogued tyre families

This high-volume inch label can carry different ETRTO width codes between models. Match the 584 mm bead-seat diameter and check the exact casing, permitted rim width and bicycle clearance.

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.

Before ordering: read the sidewall on the tyre already fitted, then confirm the bike, wheel and tyre manufacturers’ instructions. A qualified mechanic can resolve an uncertain fit.
