It appears that the photos show what is called scalloping or cupping of the outside edges of the tires.
Unfortunately, this problem can have several causes but the cheapest and easiest fix is to start with an alignment and then go from there, but you should be sure to have the shop do a full inspection of your shocks and suspension just to be sure.
Once the tires are cupped or scalloped, its nearly impossible to "undo" this wear pattern. Some people will have the tires swapped so the cupped outside edge is now on the inside.
For reference, here is an example photo of what extreme cupping or scalloping looks like. Of course, I chose the most extreme example that I could find to make it easy to see in a photo. In more typical situations, cupping is usually more subtle, so it is best found by running your hand over the tire and feeling the up and down wear pattern than seeing them.
