Put just enough air in the tube so that it holds its shape

Take the wheel and locate the valve hole

Lower tire and valve into rim valve hole and align valve so it is pointing straight toward hub; a crooked valve can lead to a flat tire later

Tuck the tube over the rim and inside the tirewall one bead at a time, avoiding kinks, bends and twists

Work tire bead onto rim with hands. If tire bead will not seat using hand, use tire lever as a last resort. Use caution when using tire levers to avoid pinching inner tube.

Re-seat the bead, starting at the valve area and working around, using your thumbs to push the bead over the edge of the rim

The last bit may be very difficult; if you need to use tire levers be very careful not to pinch the tube, causing a puncture

Push and pull the valve to make sure it is 90° to the rim

Put a few strokes of air into the tube

Inspect the tire and squeeze the bead together all around the rim, making sure the tube is entirely between the tire beads.

If a part protrudes it may cause another flat later

Inflate tube to low end of recommended pressure and inspect bead on both sides

Look for small moulding line above bead; this line should run consistently above rim

Inflate to full pressure and check with pressure gauge; it may be necessary to press downward above the valve in order to engage the pump head

Re-install the locking nut, if any; tighten with fingers
