strange pop noise sounded like a blown tire

i was driving down the road and i heards and pop like the tire blew and while i had to limp it to a pull over spot it sounded exactly like a tire blew. I then pulled over to check and the tired were all aired up. When I went to take back off i never heard it the rest of the way home. what could this be? I checked the tired and once lose so im guessing wheel bearing went out.(1997 Dodge dakota)
