I like wheels, so I'm chiming in.
Just 2 points.

There are so many A's with 16's many people
think they came stock with them!
I have found many times wheels advertised as Model A
that turn out to be 16-17-18 inch wheels.

Also just my own personal experience.
I have run 7-50-16 Firestones and BF Goodrich Silvertowns
on stock 16 inch wheels, on Model A's at least
6 times in the last 15 years, with no issues at all.
The tire mfgrs are concerned about liability,
understandably. Just my own observations, do what you
think is right.
