Tick labels bump into axes


I'm using a very large font size for my tick labels (for publication-quality figures). When I do so, the tick labels bump into the axis bounding box. Resizing the window does not change the spacing between tick labels and the bounding box, only the spacing around the outer edge of the plot. I did a search in the archives but couldn't find the answer (though I bet it's in there).

Is there a property, command, or command-combo that can be used to specify the spacing between (e.g.) the rightmost edge of the y tick labels and the adjacent y-axis?
