Valve stems and TPMS

[cosmotini]

I was washing our trailer this weekend when I noticed that the Pressure-Pro TPMS had made marks on each of the trailer's wheels. Today, I took it to a local tire shop and had them switch out the rubber valve stems with metal ones. I was happy with the amount they charged. All 4 for $21.50.

Another nice thing I found was that all of the wheels had been balanced. There are weights on the back side of each wheel. The installer made sure he did not move the tire on the wheel. He deflated it, broke the bead, removed the old valve stem and then installed the new one.

I'll have to try to rub out the mark on the wheel but I'm thinking it will become part of the trailer's "character".

good info cosmotini!

clearly the monitoring heads are heavy enough to move the rubber stems...

richL had a rubber stem failure recently, that he attributed to aging,

but it may have been precipitated by the monitor nubs.

good of the tire shop to do the balance too!

a metal stem and monitor head clearly alter balance a tad.

i'm still holding out for tpms that go INSIDE the tire at the stem, like some oem versions.

cheers

Thanks for the information. I've had them on my trailer for 8 mos/3,300 miles and have not yet noticed a problem. Will definitly get metal stems before heading south for the winter.

Hi, I was wondering about Airstream useing rubber valve stems on their trailers; My trailer came with metal valve stems, but some others, same model year as mine [actually same year, same model, same wheels, and same size trailer.] were made with rubber valve stems installed. Was this random or a dated production change?
