The top one, with the internal hubcap nubs would be a '40 - '48 Ford wheel if 16" diameter, or an F1 / F100 if 15" I think.
The lower picture shows a later Ford truck style if it is around 10" over the hubcap nubs or Mercury if 11". I've had the Ford ones in 15" and 16" diameters, and my Merc ones are 15".
