The OP is almost 4 years old, but in reading about all of the "China Bomb" problems, the name Freestar does not appear as frequently, if at all, compared to Mission and others. My Freestars have less than 3000 miles on them, with a mold date of 5207, but they look almost new.
What I learned at the rally was the Freestar name was discontinued because the mold had reached the end of it's service life. They decided not to retool it. There was nothing wrong with the tires.
