Why are my tires cupping?

Put a new set of new Les Schwab Wild Country Toyo's tires on my truck a few months ago. I had them rotated recently with about 7000 miles on them. The tire dealer noticed that there was some cupping wear occuring on the fronts. Said it might be an alignment problem, under inflation, too long between rotation. This is my third set of tires on my truck since I bought it and I've never had this problem. I keep my front tires inflated to about 55 psi. Yesterday I had an alignment done and they said it was fine, so I can rule that out. I'll watch the current fronts carefully to see if the problem keeps occuring and will probably have them rotated again at 5000 miles. Any other ideas about what could cause this kind of tire wear?
