Is it safe to put F150 tires on an expedition?

We have a 2002 Ford Expedition which was in desperate need of new tires. My husbands uncle has a 2014 Ford F-150. He sold us his tires since he bought bigger rims. They are in great condition and had them installed at the tire shop. My concern is if it's even safe? The expedition tires look so much bigger than the expedition ones. My husband keeps telling me if it wasn't safe the mechanics wouldn't have installed them, I'm just curious if it's a good idea?

It's fine for you to use the tires from your husbands uncle's truck. The tires are a bit smaller in size but they will be ok there will be a tiny bit of a difference in the speedometer readings as the tire that came on most expeditions was 265/70/17 and the f150 had 235/75/17
20 mph =19.6
30 mph =29.3
40 mph =39.1
50 mph =48.9
60 mph =58.7
70 mph =68.4
80 mph =78.2
