Glad it all worked out OP. But at 14K all 4 tires had good tread life? Were all those miles on the same set? At 14K mine needed to be replaced. Granted I do almost zero highway miles and those 14K miles included 4 dry track days and 2 wet, but I'm surprised they didn't at least replace the other tire on the same axle.
