'50 Inner tube
 

I want to use the original 16" wheels on my '50 F-1 and need to get tubes. What size valve is used on the inner tube to match the hole in the wheel... TR15?

Either the small or the big one:-X04. I really don't
remember but a 16 prolly takes the bigger stem.

Ya can always drill it out for the bigger one. Be sure to smooth
the edges if ya do drill it oversize.

These have worked on my '49 with stock 16 inch wheels and bias ply tube tires.
