Thanks Al. We've been able to have the four tires replaced (LT 225-75R-16 M/S) at no charge by the local Michelin dealer (Boulevard Tires) in Orange CIty. The new tires are the same brand as those under recall (Michelin LTX Mud and Snow), but were manufactured in October 2013.
I had to pay to replace the spare tire which was an LTX A/S (all-season). Incidentally, the new tires were made at their Nova Scotia plant in Canada but were less expensive ($216) than what Canadian Tire asks for in New Brunswick ($234). Maybe the exchange rate explains the difference.:@
