Correct M37 valve stem number for stock rims and tires

[Austringer]

What is the correct inner tube valve number for stock m37 rims and military tires, tr75a work but the valve stem is pressed hard against the rim and takes a screw driver to pry the valve stem away from the rim to fill it. thanks in advance
