What kind of valve stems are in your trailer tires?

[Kevin Cooper]

This question is for TT and 5th wheel owners. What kind of valve stems are in your wheels? If you have some all steel ones, good. If you have rubber ones, are they partly metal showing below the cap? If so good, maybe. Are they rubber ones like in your car? Not good.
The standard ones like in your car are rated for 65PSI. The better ones are from 100PSI up. And the all metal ones are rated up to 200 PSI.
There have been many many tire discussions in this forum about airing up tires to max cold pressure on the sidewall of 110PSI. And also many discussions about shredded tires.
I’m wondering if some people have 65PSI valves, running 110PSI cold, reaching 115 hot and are blowing out the stem and then turning the tires into shreds of rubber and steel wires.

I believe mine are all rubber with metal at the cap. Tires are the GY Endurance so always air to 80 PSI cold on travel days. I would like to replace them all with metal stems but have seen and read where there can be some difficulties determine which is the correct one for the wheel.

I don't trust anything but heavy duty truck valve stems.

I have the TPMS sensors that Ram supplies wit the truck with the trailer TPMS option...its the sensor with i believe are aluminum? stems and plastic caps.

Before that the trailer had rubber valve stems and plastic green caps - Goodyear Endurance tire max pressure 80lbs.

Metal stems

Mine have a rubber base and brass stems. I made sure they're rated for the 80psi I run in my E rated Kenda Karrier tires.

Metal on trailer

All metal. Replaced the OEM rubber ones the first time I replaced the tires. Spare too.

All metal on camper. Truck has the metal/rubber that came with the truck.

You should be ALWAYS running a TPMS that has been properly programmed to warn as soon as the PSI has dropped below the PSI required to support the load on that tire.
TPM systems should be tested at least once a year to ensure that each sensor sounds the alarm to the driver of air loss.
Basic "snap-in rubber stems are too flexible and the weight of a TPM sensor can eventually cause the rubber stem to flex and fail.
"High Pressure" rubber stems while stiffer can also bend and fail
Metal "Bolt-In" stems are the only acceptable type of valve stem for use with external TPM sensors.
