Alignment places, like many mechanics, are often self grandiosizing.
There is no reason to not recommend Hankook and the 7/16ths may not be out of the realm or it might be exaggerated.
I guess now you have mismatched tires front and back?
Did they do a rotate while they were at it all?
The oil change dealer didn't know in advance his equipment wasn't capable?
Lotsa questions outstanding....
