Tire bead seating help?

I'm having an issue trying to get this tire to fully seat. 

Oddly enough, it is holding pressure above and beyond with operating range is.  

but, how do I get it to seat correctly?  Is more lube still the right answer?

Dish soap.

Dish soap + strap around the outside of the tire to help push sidewalls out

And bouncing 

Yes. All of the above.

Aluminum wheels are tough, friend of mine believes the air just "migrates" through the metal.

Buy a tube.

Having just gotten done my own rear tire a few months ago I can tell you everything was extremely difficult until I started liberally spraying on soapy water from a spray bottle liberally on the rim and tire. VERY liberally and often. That should fix the issue quickly.

I agree with the dish soap. What PSI are you using to try to get the bead to pop over? 

In reply to brandonsmash :

It was up to 80..  I probably don't have enough volume.

The strap, bouncing and even slowly riding it hasn't helped.

More soap it is...

You need more flow.

I would leave that wheel/tire out in the sun for a while to get it to soften up a bit.

More lube.

Make sure there isn't a rough spot on the wheel that the bead is catching on.

The garage is warmer :(

Mid 30s this morning again

Lots of dish soap brushed on the bead.  But it has to be on the inner surface of the bead before starting inflation.  {Putting it on the bead surface of the rim after you start inflating is not as effective. )   We had a plastic bottle of soapy water hanging off our mounting machine with a soft bristled brush to put soap on the inner beads before mounting and inflation.

The belt around the circumference will help force out the bead if you aren't getting pressure but once that catches the belt won't do anything.  Its all air pressure and reducing grip with the soap.

If its really cold try leaving the tire/wheel in your  house overnight to warm up.

Dish soap works. I've had better luck with silicone spray on really tough installations though (I have one bike that's always a nightmare).

70 psi is as high as I've ever gone to seat a bead. I connected the air chuck to the wheel outside the garage with the regulator turned all the way down, then closed the door and hid in the garage while slowly turning the regulator up until it seated. I was scared, there's a lot of energy there. I HATE changing tires on that bike. 

Moar psi!

and remove air, rebreak the bead, apply some dish soap and try again

80 psi, good lawdddd
