Yes, I know the type of wheels, and that stems like this were used on them. Schrader made these in several sizes. The Schrader 777 was used on Model T Fords. I just wondered what particular cars used this larger 725.
The metal stems on tubes currently being sold for 30 x 3 and 30 x 3½ tires are larger than the Schrader 777 used on Ford cars. They are a reproduction of this Schraeder 725 valve stem. I wonder if anybody here can tell what cars used the 725 stem. One person suggested that it resembles the stems on his Pierce but he didn't know their number.
