replace it as soon as possible with a road tire/wheel that is the same size
and type as the road tires and wheels that were originally provided by
Ford. If the dissimilar spare tire or wheel is damaged, it should be
replaced rather than repaired.
A dissimilar spare tire/wheel is defined as a spare tire and/or wheel that
is different in brand, size or appearance from the road tires and wheels
and can be one of three types:

size and may have “Temporary Use Only” molded in the sidewall
2.Full-size dissimilar spare with label on wheel:This spare tire has
a label on the wheel that states: “THIS TIRE AND WHEEL FOR
TEMPORARY USE ONLY”
