You may still have a problem if your compressor is very small and has a very low flow rate/small diameter hose. If that's the case try borrowing a unit with a higher flow rate/bigger hose.I use a local convenience store's air hose. They have free (a rarity anymore) air available, and the hose is the type that you squeeze a handle to send air into the tire.
How do you inflate without the valve core? Every one I have seen requires the valve core.The air will go in without the valve stem installed. It just comes out again when you remove the hose. Shoot the air in until the bead seats. You should get two good pops, one as each bead seats. Then take the hose off, and reinsert the valve stem. I just wait until the pressure in the tire is gone, screw the stem in, and then inflate the tire. Once the bead is seated, it will stay in place without any pressure in the tire.
No valve core inflation - a hose end/connector like the tire shops use. It clamps on the valve stem.I think this is what Summit670 is referring to: (Though you'll need some way to control the air supply)

Tire shops use these to inflate very large tires like tractors and combines as it could take 10 minutes to fill and ypou'd get a pretty sore hand holding a regular chuck for that long. They have about the same filling rate as the chucks without the holder.
I install quite a few of my own tires and I really know what you're going through.
Try laying the tire flat, or flat with small blocks under the tire to hold it up. Also try rolling it a bit while on edge. If one thing isn't working go directly to another,keep changing angles you are holding the rim etc.
As with other aspects of our lives lots of lubrication can lead to success. A squirt bottle with a pretty rich detergent water mix works well.
Removing the valve core is also a must when things don't go well...filling rate is much higher.
Tire shops also have a puffer they use to help expand the tire to grab the rim. It's just an old propane bottle with a quarter turn valve, large pipes and a nozzle that directs the air between the tire and rim. A quick turn of the wrist and with a blast of air the tire expands to contact the rim and the already running air chuck takes over.
We used to do this with explosive gasses. In the interest of safety I won't get into that.
Sometimes, with all your efforts, a tire won't seat. I begrudgingly take those to the tire shop and they usually do it for free just to prove who's the man.
Good luck
So are y'all saying that it will still work without the valve core installed?
