I've had FOBO's on the OEM rubber stems since Oct., 2025, no problems (yet) and the FOBO's work great as a TPMS. I'll be getting tires in the next couple of months so I'll have the metal stems that came with the FOBO's installed then.

Well you can all do what you will of course BUT, I will still and always say a "Tee valve" is the only what to go with the cap style TPMS
Going on 6 years with my FOBO Bike 2's
I had rubber valves at first, swapped that for metal quick as my tires were do for change at that time.
Found that to be a pain in the BUTT when I had to put air in the tires and was doing that to often so on my last tire change I put the Tee valves on and WOW
SOOoooo much nicer to put air in with the Tee Valve because,
#1 I no longer have to remove the sensor to put air in
#2 I have the tire presser on my phone so I don't have to carry or find or rely upon a manual gage,
#3 AND I don't lost air putting the darn cap back on! not to mention the difference from the manual gauge and the TPMS sensors reading
I'm sold and your.... ah, saving a buck? on your Flippin "HARLEY'S" LOL! That's funny
go internal or Tee Valve (IMHO)

Don't overtighten the T-valves on the wheel, by the way - it doesn't take much torque to seal them or to squeeze the rubber seal out of place.

YMMV but I believe the Key Word here is "ALMOST".

I used to have the internal ones, lasted about 3 years.
When I went to buy new ones the company had stopped shipping to USA.
So I went with the SYKIK external ones with metal valve stems.
Batteries in the valve stem unit are replaceable and the head unit is rechargeable.
Can't really read the screen with sunglasses on while riding, but it's only slip down on the sunglasses and I can see the screen, but checking tire pressure before a ride is much easier as I don't have to get on the ground to check them.

Talked to Costco today. There safety #1. Patches only and none past the last rain groove.
If you run it flat, they want to replace it.
They said they have never seen an issue with them and nothing in their lectures there unsafe.
