The technique, which solves most cases
Get one side of the tire on. Then, with the second side, start opposite the valve and work both ways round toward it.
As you go, push everything you have already fitted into the center channel of the rim. That is where the slack is. Do this repeatedly — every few centimeters, not once at the start.
Leave the valve for last, and push the valve up into the tire before the final section goes on. A tube bunched around the valve is what takes the last of your slack.
Warmth helps
A tire that has been in a cold garage is stiffer than one that has been indoors. Ten minutes in a warm room genuinely changes it.
Levers, if you must
Two plastic levers, and use them to lift the bead over rather than to pry along. Levers that clip onto a spoke free a hand and turn a two-hand job into a one-hand one.
Go slowly near the end. Almost every pinched tube happens in the last twenty centimeters.
Tubeless is harder
A tubeless bead is designed to grip, which is the point. Some manufacturers engineer specifically around this step — Panaracer names BeadLock on its GravelKing.
Soapy water on the bead helps it slide, and it evaporates.
Before you inflate
Push the tire sideways all the way round on both sides and check no tube is visible. Then inflate to low pressure, check the bead line sits evenly all the way round, and only then go to riding pressure.
When it genuinely will not go
Check the ETRTO numbers on the tire against the rim’s. The bead seat diameter must match exactly.
The questions riders ask
Why does pushing the tire into the middle of the rim help?
The rim is deeper in the center than at the edges. A bead sitting in that well has slack, and that slack is what lets the last section go over. A bead sitting on the shoulder has none, which is why the last twenty centimeters feels impossible.
Can I use a screwdriver instead of a lever?
No. A metal edge damages the rim and cuts the tube or the tire bead, and the damage is often not visible until it fails. Plastic levers cost very little.
