I have started researching what tires were used on the brass era Model Ts and having a hard time of it. The question of “what tire brands were used on the early Model Ts” has been asked before but I have not really found a complete answer to the question yet. I fairly sure that FIRESTONE and DIAMOND brands were used but what else? What about GOODYEAR, FISK, US TIRES, GOODRICH, and others?
Another question is about the tire repair kits/outfits. Was a tire patch kit supplied with the new cars that matched the brand of tires on the car? If a new Model T came with FIRESTONE tires, was a set of Firestone marked tire tools and patches included; or did someone just throw in a set of tire spoons without regard to the brand of tires on the car?
i think tires are listed on the build sheet. charley
The build sheet for my '10 Touring shows the car was shipped with Diamond Tires.
I have a handful of early (1909-11) build sheets. The ones I have list: Diamond, Good, and either Fire or Fisk. The explanation pages that accompany the sheet state there are four tire possibilities: Good(year), Fire(stone), Fisk, or US Tire.
Surprisingly, the Model T Encyclopedia doesn't have a section on tires. Here's an opportunity for someone to do some historical research.
Here's another thread on the topic of tires:
Does anyone have scans of build sheets they can post?
Most of them are so faint that they cannot be scanned. I tired doing mine with no success. The way they were reproduced originally was poor and it just gets worse with every copy. There may be a way to enhance them a bit but it is certainly beyond my skill set!
