I don't know how that would look like, a G70-14 squeezed on a 5.5" rim. I think that's too wide.



That's because:
the STANDARD wheel was 14x6.0" (with "dog dish" hub caps or full wheel covers & other combos)
OPTIONAL in 14" were (new for 1971) 14x6.0" "ROAD WHEELS" w/chrome trim ring at $90.55
OPTIONAL for the G60-15s were 15x7.0" "RALLYE WHEELS" at $58.95

NO 14" "RALLYE WHEELS" on 440, 440+6 or HEMI '71 b-bodies.
