Tyre install help

I'm new to building BMX bikes. I've purchased complete wheels, tyres and tubes.

When I install the tyre to the rim, after pumping some air in the bead doesn't seem to be setting - the tyres are pretty loose around the rim, when I inflate I'm able to see the inner tube popping out either side of the rim. I have tried to get the tyres to set as I gradually inflate - with no luck!

What am I doing wrong?

Tyres are 20x1.85, Tubes are Kenda 20x(1.75-2.125) and Rims are 32mm width, 21mm height.

Well, you need to put the beads inside the rim. It doesn't look like you've done that.
