What exactly is bead seating?
Michelin says do not inflate past 40 PSI to seat the bead - even the tire is rated for max 44 psi cold.
Is this something done at installation and once the tire is on it can safely carry 44PSI?

Ever watch a tire being installed? They have to get the tire bead to seat on the rim. The bead will usually make an audible "pop" when it seats. Excessive pressures can explode the tire and rim assembly (or so I was told by the dealer).

Personally they usually pop in for me at about 7 psi. They use cages for heavy truck tires b/c if they let go it'll cut you up.

most tires will seat with a lot less than 40psi. the seat pressure had no effect on normal operating pressures. when i did tires, certain brands would seat at extremely high pressures. michelin pilot sports, and a lot of other high end tires will seat high because they have thin widewalls are are usually being stretched on a narrow wheel.

As bdc said, most will seat well under 40. Occasionally, though, they don't. Proper procedure is then to deflate, relube to include lubing wheel mounting surfaces, and try again. Occasionally this is still not enough. Thats when you stand waaaayyy back, use the tip of the toe on inflator, and air till she goes! Have hit 80 a few times! Pucker factor goes through the roof!

Truck tires in cages are a whole 'nother spincter tightener.

Hmm. When I get new tires I usually get some gummy looking thing around the edge of the rims. I surmise this was lubricant of some sort? I thought it was a sealant.

Another guess: protect the rim edge during shipping and mounting?

We had some very low profile tires that would not seat [AMG].
We ended up using starting fluid and a match.
Well, it worked.

This is very dangerous!!! There are a few Youtube videos of tires catching on fire and once that happens the rubber is no longer fit for use.

Not to mention that this is a good way to break beads. People sometimes get killed when beads break in mounting.

If you can't get the tire to seat doing it the normal way, something is wrong. You need to figure out what is wrong and correct it.

I just mounted a tire using only screwdrivers. It was to test for rim leaks. My mom came out to see what the bang was when the bead seated. I wish I could mount all my tires myself but it's not worth the risk to save $50. I'll stick to bike tires.

I've mounted at least a couple dozen tires in my basement. I put a little lube on the rim and stand the tire upright (for safety) to seat the beads. It makes a loud pop but I've never had problems.
