What was the last year that model Tís left the factory with white tires ?
I don't know the answer for sure, but the annual catalogs of Ford cars showed them in white (or off-white) tires through the 1925 model year. Dated assembly line pics would give a more accurate answer to your question, if someone has those.

Could be the 'white' tires were early smooth treads. The later tires with pattern grip had the carbon added for strength and that turned the tires black.
These ads are from 1916 and note the color of the tread as black, and sidewalls different color, red and sometimes white too.
And the black and white photos and ads of the day can't provide proof of tire casing color, but IMO, the later T's of the steel radiator era wouldn't have white smooth treads, and the treaded one usually had black or at least a gray off-white, or combination, depending on the tire manufacture that was supplying the Ford assembly branches at the time. Ford used many different tire companies for its tires.
Above is period road side tire work, the tire doesn't look white to me compared to the white shirts they have on!
See if you can find the link back to this post.
An interesting article inspired by a trip to the Piquette Plant.
Peter, good article. Thanks.
Yes ! Peter, many thanks for that link. The article is informative and well written. It also gave me a hint of insight that many in the younger generation probably have never experienced "pure carbon" aka "soot" - !! (Two excellent sources of soot I deal with daily pictured below)
