There does not seem to be a direct correlation between the original 
tiger:cfcc values and the highway=* tag any more. Some roads were 
(properly) promoted to secondary since the original import. Some of those 
should be promoted further (to primary).

I wouldn't focus so much on those original values, or what was originally 
done at import, since the TIGER classifications are known to be incorrect 
as compared with local knowledge and official definitions by city planners. 
Did you see my previous post? I provided a link to the planning data that 
describe the official planning categories and how I would map them to OSM.
