I found this image on the Wisconsin Historical Society web page. It is interesting because they know it was taken in Sept of 1916 as referenced by the tractor show banner in the background. I know Fordson tractors are listed as beginning in 1917, but would they have been showing Fordson tractors in Sept of 1916? Also, did all 1917 Model T's have the white wall tires or all white tires? Would a 1918 also have used the white wall tires?

Fordsons werent sold in the U.S. until April of 1918. Anything built before that
were late 1916, early 1917 "X" prototypes and Britian-bound Ministry of Munitions "M.O.M." tractors.

Although the banner references a tractor show, and the description cataloged with the photo mentions the local Ford dealer as eventually selling Fordsons, it is too early for there to be any Fordsons at that gathering

The two surviving original front tires from the 1917 "Rip van Winkle" touring are smooth, double-side whitewalls. They were manufactured by United States Tire Company and had Ford script.

It was a June 1917 car, most likely assembled in Minneapolis as the original owner resided near Center City, MN.

Before the cost came down the tires were made with natural rubber case and capped with the black tread. (sorta like a modern retread) The cost was high at the time for doing an all black tire. They found that adding carbon black to the rubber increased it longevity.

This news paper article describes the new Ford tractor at that time, paper was 2 Dec 1916 Australia.

Hi Frank
That article is probably a mention of the 16 August Fremont Nebraska Plowing competition/ tractor show where ol' Henry himself demonstrated his newly proposed tractors. These were the prototype "X" tractors of which FoMoCo built about 15 total.

Note the original new style top cover (boot), which was introduced for the 1916 models.
