Yup, those would be fine on 14x5.5’s. They’re also the widest recommended tires you can run on 5.5” wide rims.
Not that people don’t run 225/70/14’s on those rims, I’m sure some people do. But the tires will be squeezed down a bit to do it, which messes with your tread pattern. And some shops just won’t install tires if the rims aren’t within the recommended specs.
