Do you really think Ford would install a tire that can't handle the vehicle GVWR?

It's not "tire size" that some should be talking about but WHEEL size. The wheel bolts to the axle and needs to be rated to be on that weight axle. A tire is mounted to the wheel. A wheel that is designed for a 22.5 K axle will have a different bolt pattern than the 18k so the the lesser rated wheel can't be overloaded.
