In my case, Tile Image loaded from remote url and tilesloaded event was triggered before render the image.

I solved with following dirty way.

var tileCount = 0;
var options = {
    getTileUrl: function(coord, zoom) {
        tileCount++;
        return "http://posnic.com/tiles/?param"+coord;
    },
    tileSize: new google.maps.Size(256, 256),
    opacity: 0.5,
    isPng: true
};
var MT = new google.maps.ImageMapType(options);
map.overlayMapTypes.setAt(0, MT);
google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
    var checkExist = setInterval(function() {
        if ($('#map_canvas > div > div > div:nth-child(1) > div:nth-child(1) > div:nth-child(1) > div:nth-child(2) > div > div').length === tileCount) {
            callyourmethod();
            clearInterval(checkExist);
        }
    }, 100); // check every 100ms
});
