Air is a setup decision

01 / Read the whole system

Identify the tyre size, tyre construction, rim model and whether the setup uses an inner tube or is tubeless. Read the tyre and rim maker’s compatibility instructions together. Hookless rims have additional restrictions; a tyre that physically fits is not necessarily approved.

Use the frame and component manufacturers’ instructions for pressure values and limits. Do not exceed the lower applicable maximum of the tyre and rim, and observe all minimums and compatibility restrictions. An ambiguous marking calls for clarification from the manufacturer.

02 / Measure rather than squeeze

1. Use a gauge suited to the valve and pressure range. Inspect the valve and visible tyre condition first.
2. Compare the measured value with the recommendations for the exact setup and load. The maximum marking is a limit, not a personalised target.
3. Inflate gradually with the correct pump connection. Check that the bead is evenly seated and the valve is straight.
4. Recheck after removing the pump head. Repeated unexplained loss needs investigation rather than repeated top-ups.

03 / Record a starting point

A useful setup note contains the tyre and rim models, tube or tubeless system, luggage carried and the pressure actually measured. Record front and rear separately. These notes deliberately supply no generic pressure table.

A cut sidewall, exposed casing or a bead that will not seat is a repair issue. For a conventional inner-tube puncture, continue to A tube puncture. Tubeless seating and sealant work are outside this notebook’s procedure.
