seating bead on new tire

Yeah I was understanding you couldn't really do it if you left the valve in, and yeah your air compressor won't put out enough air fast enough.  You're trying to pump air in faster than it's leaking out.  You might be able to work it with ratchet strap but you'll probably save time just taking it to a gas station with a big air compressor and doing that even if you have to go back once or twice.

I was having a hard time setting the bead on one of my tires and I was using a VERY old weak air compressor. All I did was sit on the tire with my feet on the ground and slowly lifted myself off the tire until I could hear the air rushing into the tire instead of leaking out. No problem....then i went to Wawa for the more powerful and free air compressor.

I'd try to take the valve core out with the tool and fill it that way till the bead seats.  Otherwise, take it to the gas station  or local tire shop and ask them to fill it till it beads.
