Correct way to install metal valve stems?

OK that's interesting....typical metal valve stems mount from the inside and the locknut goes on the outside. Are the sensors that hard to remove that you need this valve configuration?

I'll stick by my original comment, if it ain't leaking.....

I agree if it's not leaking. But, I am picturing the little grommet on a curved surface being flattened by a flat/dished washer and am not sure if they will stay leak-free in the long-term? I came across a post by JBarca from a few years ago where he had trouble. Interestingly, he was trying to use the same valve stems. He found some valve stem grommets at NAPA that were thicker and had more to cushion when tightened up. The tire shop said they would re&re the valve stems for free if I thought it wasn't right so I *might* consider the NAPA grommets.

Removing the sensors is easy. Not sure if I have an answer as I'm new to a TPMS. Seems like the benefit is not having to bother with resetting the monitor if a sensor is removed? I've also got the little locking things on them to prevent theft.

Despite what Hawkshead says, I'm going to go with the grommets on the inside. I was wondering if there was a washer available that is concave in one direction to accommodate the curve on the rim surface but I haven't found one.
