In my 30 years of airline flying, I never saw jetliner wheels with known fuse plug deflations, so I have no direct sightings. On a multi wheel bogie, with just one deflation, I would think a cursory look might appear that all tires properly inflated. If all, or most plugs let go, the wheel rims are gonna drop right down to the tarmac on the deflated ones.
Did blow fuse plugs on an F4 Phantom once after taxi in. The rims settled onto the flightline, very noticable.
