If so, rethink that. I have encountered numerous incorrect spellings in Tiger data when compared to street signs or plat maps. I have seen Tiger use 3 variations of spelling on different sections of the same street. It is also common for Tiger to have incorrectly labelled streets, putting a name on a nearby street rather than the correct one. I might use a Tiger value where there is no OSM entry, but would not replace an existing OSM value that differed from Tiger without a local survey.
