I recently purchased a TST tpms system with flow through sensors. I now need metal valve stems for the trailer and the truck. Putting metal valve stems on the trailer is no problem but the truck is another issue.
Even though the truck has a factory tpms system, I want to use the TST system because Iโll be able to watch it in real time like the trailer. Using the rubber factory stems is not recommended by TST because they flex too much while at highway speeds causing air to escape from the stem where it attaches to the rim.
In Missouri (and possibly other states) it is illegal to disengage/remove factory tpms sensors located inside the tire. I had a nice discussion with my tire guy and he told me this, much to my surprise. I searched the internet and sure enough, itโs true.
Ram does not make a metal valve stem that attaches to the factory tpms so Iโm searching for an aftermarket stem that does.
Iโve seen an aluminum stem at AutoZone that might work (Iโll have to compare it to the OEM rubber stem at the auto parts store) but Iโve read where the aluminum ones corrode too much and cause more issues.
Can anyone with this same issue tell me what you did?
