Michelin Tire Recall - How Long To Get Replacement Tires?

My replacement set of Michelin 225/75R-16 LTX M/S2 are ordered. No ETA yet. When my dealer called them they asked him if I would except a substitute. He said no and that was the end of that. I'm not in any hurry as my recalled set only has maybe 2,000 miles on them at the most and from the looks of the weather report it's not going anywhere for the next few weeks.
