As an old car nut, as well as a train nut, wooden spoked auto wheels usually had twelve spokes. And pressed steel wheels appeared on 1928, maybe an option on 1927, Chevrolets, but the Model A Ford appeared first in 1928, and on wire wheels, with, I think, wooden spoke wheels as a not very popular option, that I doubt did not survive 1929, because I have never seen a Model A (and there are a LOT of them surviving) on wooden spoke wheels. Chevrolet, at least by 1929 was offering wire wheels as an option, and wire wheels were common until 1935 on most makes, when Chevrolet Master models, and I think (I am no Ford expert) all Ford models went to stamped steel wheels. Some larger cars still kept as standard or an option wooden wheels because "split rims" (you just remove the rim and not the wheel to change a tire) were thought easy and familiar, possibly until 1930. Like all things wood, wooden wheels are maintenance prone. (A lot of inexpensive models of late twenties/thirties Fords appear on modern, "hot rod wheels", and demand a change, to wire wheels for an accurate period model.)
