Info needed: 9.00-16 tube stem size?

[Bob Phillips]

Hi Rob,
My purpose is to build a road vehicle ( to whatever extent a cmp can be considered a road truck). I have used the larger tires in the past with smaller tubes but they were heavy duty, heavy rubber tub es. At this point I will pull apart some more old wheels and try to come up with a good set of 4 heavy rubber tubes, by the way do you (or does anyone) still use replacement valve stems É I remember when the tire shop would burn melt them onto the tube when the old valve stem had failed.
