[Healeys] inner tube

[gvernau at containerhouse.com (G. Vernau Sr.)]

Does anyone know the proper size inner tube for 165-15 tires.  Auto parts guys
seem
pretty helpless about this. Amazon shows 2 sizes that maybe look right 
(1)G/Gr 15 TR13 and 
(2)700/750 R15/16
Also, anyone know the code for the type
of valve stem. I found a tube in a parts store but it had a long valve stem ,
for trucks I guess.
