Which valve stems for tpms ?

Thanks mrekim, that stem sounds perfect for our application from all I've read and learned thus far. Just hopeful that this stem will seal ok inside our aluminum wheel.

I went ahead and ordered a full set of the Haltec stems figuring that if they don't work for me I'll offer them to someone else.

Thanks again.

Its getting time to travel for the season so I just now went ahead and did the final ordering.

I ordered 5 new GoodYear LT Cargo G26 225/70/R15 tires to replace the ST-type tires on the TT, and I also ordered the TST507RV 8 sensor TPMS kit for TV+TT.

I've already ordered and received metal valve stems from Grainger, but I won't know until I go to mount the new TT tires if the metal valve stems will work with my TT wheels. I found another post by wmoses (thanks wmoses) in the Tech Corner forum about using fuel line pieces to strengthen standard valve stems in case the metal valve stems won't work with my TT wheels.

It took three visits to the tire store to get the new TV tires balanced properly last Fall and they are finally good now, so I'm thinking I'll probably use the fuel line pieces for the TV valve stems. I ordered the original style sensors (not flow-thru) for the TST507.

This has been quite a learning experience and many thanks to all who responded and helped me figure all this out...

I've had the TST 507 (non flow through) system for about 3 years and love it. Only complaint about the flow throughs I've read is a slow fill rate.

For sure go with metal valve stems. TST originally told me I could run rubber stems but the weight of the sensor caused them to flop back and forth so much so that they left marks on the rims and 2 of my rubber stems cracked. Metal valve stems only for me.

Thanks Ron3rd, I had meant to include the link to the thread with the fuel line pieces so here it is. The poster says it works well and it seems like it would.

From what I've heard, that mod seems to work ok. Anything to keep the rubber stems from flexing will help. The next time you change tires, have them put the metal stems on. JMHO

MartyW: Be aware that different wheels require different diameter valve stems. My cast aluminum wheels require a very small diameter valve stem and my tire installer couldn't find a size small enough. Had to go metal re enforced instead.

I had the TST Flow-Throughs installed on metal valve stems. The metal valve stems that they installed had a shoulder that fit against outside of the rim and used a rubber grommet and metal washer with a nut to tighten everything on the inside of the aluminum rim. I then had the tire, wheel and sensor balanced together.

Hi,

See my post, here Mounting metal valve stems in trailer wheels - Need help

I had a heck of a time but in the end I did solve it using the NAPA metal stems. I happen to have the unique rim that they punch the hole in a curved part of the rim.

When I upgraded to LT tires and 16" rims, those rims had a nice flat formed depression for a metal stem.

I agree, you need metal stems on a TPM.

Real simple get the valve stems the TPMS manufacturer recommends.

Reporting back on the valve stems. The Grainger N-1600 Haltec aluminum valve stems worked perfectly in my main 4 TT wheels. The spare had the stem hole at the edge of a radius like JBarca mentioned, so on that wheel I used a short re-inforced rubber/brass stem since it is a spare. All the stems went in without issue except for one wheel that would leak whenever the stem was being tightened. It turned out that particular stem had been installed incorrectly with the small metal part on the outside of the rim installed upside down so that it didn't seal down over the rubber piece coming from the inside of the wheel. Thanks again to all who recommended these stems.
