What 27.5 x 2.5 means
A broad trail and enduro size normally paired with a suitable modern MTB rim and generous frame clearance.
Nominal sizes are a starting point, not a guarantee of fitted width. Two tyres carrying the same size 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.
