To further expound on this read AC 20-35C and it'll suggest how strong the
ropes should be, and how it should be tied.

You'll notice that few airports place the tiedowns so that the plane can
be tied down in the correct manner, i.e. they have the tail tiedown much
too close to the wing tiedowns and you can really get the proper angles.
