A 3.50 x 19 tyre, particularly the Avons can be quite difficult to fit in the winter. Better if they are warmed a bit to help the tyre to become more supple. Never used talcum but the wife's fairy liquid on the beads does help. If you've done it right you shouldn't have to use a lever to get the last bit over the rim as they should just walk on - start (to remove) and finish(when refitting) at the valve. That ensures that the opposing bead is right into the well of the tyre. A little air in the tube helps to keep it out of the way. No pressure, just enough to inflate it a little. Put the retaining ring on the valve stem but don't screw it home. That allows you to push it into the centre to keep it out of the way, but without it getting lost.
