Just make sure the off brand tires are the proper size and LT tires properly rated for the vehicle. If they are, and are not crazy noisy, I'd just run them and replace the steer tires. The dealer might give you a few bucks credit on the nearly new 2 yo tire, if they keep used tires in stock, which most do.
I have no experience at all with the FMCA Michelin tire deal but it sounds like great pricing that will justify the membership several times over. Apparently many people join just to get the tire deal. Follow the link to read about the deal.
