Metal Valve Stems ??
What is considered a metal valve stem. I have some some "metal stems" that also have a rubber section. I have seen some that appear to be all metal.
If using with Steel or Aluminum wheels do you need to consider different "types"
Basically I see a lot of talk about metal valve stems and using with TPMS but it seems there is some variability in what is considered a metal stem.
New to this area so pardon my question if it should be more obvious.
Thank you

For TPMS all metal is best.
I started with rubber that had a decorative metal sleeve on my Jeep. After one trip you could see where the TPMS sensors were hitting the wheels from flexing. Immediately changed to all metal.
Went with https://yourtireshopsupply.com/categ...lly-valve-kits on the RV to get rid of the extensions.

A metal valve stem is just that. If you see rubber, it is a rubber valve stem. Most, if not all, tpms manufacturers stress the need for metal stems as the biggest failure of wheels with a tpms is from rubber stems. Steel is preferred, brass is ideal as there is no dissimilar metal corrosion and aluminum will do with a touch of di-electric grease. Most aluminum rv wheels are very hard to fit with metal stems that will fit the mounting area and not stick out so far that a sensor will get taken out by a curb. Steel wheels are very easy to fit as they have no recess that has to be dealt with. Good luck as every different aluminum wheel has a different recess and angle. Not standard like steel wheels.

Ok so basically you take the RV to a tire place and have them replace all the stems, correct ?
Thank you for the info.

Yes, the standard rubber valve is only rated for 65 psi, the best 80 , metal valves as well as being a solid mount for TPMS sensors are good to 200 psi.

I was having trouble with my TPMS and partial rubber valve stems leaking air whenever I went over 60 miles/hr. Last year got so bad that I took them off. So this year I figured I would change to a metal valve stem. Called around. The tire store that I go to for my cars said they didn't have any metal valve stems ( and didn't offer to try). Called another tire place and they suggested a Goodyear tire place next to a truck stop. Called them and set up an appt. When I got there they took the first tire off and discovered that the metal valve stems that they had wouldn't work with my rims. Evidently the shelf on the inside was to narrow to accommodate the stems that they had. The metal rim on the inside of the stem was too big to fit my rims. Discouraged I went home and did research on valve stems thinking it was just a problem that their stems were designed for bigger truck rims. So I ordered several different types including TR416, TR 416S and others. All of which screw down from the outside. And just to be sure I also ordered a Gorilla VS402 inner mount although once installed you can't check to make sure the nuts are tight.
A neighbor works at an auto repair shop that also does tires and he agreed to take a look at it. He tried to install the TR416 and some of the external mounts but they all were too wide on the inside for my rims. The only one that would work was the Gorilla inner mount type. So I just have to hope that none of the nuts get loose.
But just finished traveling from Iowa to California and no more problems with leaking air! WooHoo!
Hopefully things will go smoother for you. But its a relief to now have a reliable TPMS.

My Stems
It finally stopped raining enough to take a look at my Stems. Looks like I already have metal stems from the mfg.
Ignore the dirty wheels 
I think I'm good to go with the TPMS System
