My dad got a set of factory take-offs (brand new OEM wheels and tires) for less than the cost of a set of tires from the dealership where he buys his vehicles.You might check at a Ford dealer. I just tell mine what I want and they take care of it at a good price.
In the past, I've rarely replaced tires with the same make and model, but on my '13 F-150, I've stuck with the Michelin Defender LTXes that came on it from the factory. I've gotten really good life out of them, at least when the "road hazards" haven't taken them too young. The last one I had to replace had close to 50K miles on it when Yale Ave. took a bite out of it, although it was getting close to the wear bars.
