Trailer TPMS Sensor Size (Too Small)

Went to have the sensors installed today, and they are too small in diameter for my toy hauler with G-rated tires. Tire shop could not modify to get them to work (which is good, as I would not be comfortable with "modified" valve stems/sensors).

 

I read a post somewhere about this, but I cannot find it when I search.

 

Does anyone have a solution or alternate set of sensors that are compatible?

 

Thanks!

America's Tire ordered larger stems and will attempt to rebuild the trailer sensors for me.  I will report back when complete.

Yes, I actually posted a new thread. The new stems would not fit, but we did find a solution.  Used the older style ford "bands" / giant hose clamps and placed the sensors inside the tire/rim.  Pic attached.  Works great.  Hope this helps.IMG_6655.thumb.jpeg.33b14132b3404d65d521fe17f0e3fe6b.jpeg

Thanks for sharing. Fortunately, mine installed without an issue. My trailer tires are 225/75R15. Must be smaller than yours.

Just received them today.  They utilize the GM swivel base and attach to another make of TPMS valve stem with machine screw.  The thread fit is tight so I don't see any issues with it ever loosening.

When you used the bands did you have to modify the sensor or the attached valve in any way for it to work or did you just put it into the tire /Rim as it is or did you take out the valve stem core? Thank you

Another fix: 

  On 3/23/2020 at 8:33 PM, SenecaDriver said:

My trailer rims had the large hole, supplied sensors are for the small hole rim,  I bought 6 metal stems that had rubber seal for both hole sizes.  Slide the large seal over the supplied stem , use the washer and nut from the metal stem, you now have a stem for the larger hole rim.  Do not remove any of existing seal from the supplied stems. Tried that on one and it leaked.  All working as advertised on all 6 wheels.  

@SenecaDriver -Thanks for this fix.  The valve stems that fit both sizes are called TR-416.  NAPA had them in stock at the local store.  NAPA Part #: NTH 90416

However, the threads on the TPMS sensors were too short to use the TPMS's existing seal on my aluminum wheels (maybe on a steel wheel they wold work?), anyway, my tire guy removed the original seal and was able to get them to fit.  They've been on for several days now @ 80psi with no leaks.

 

Once the Sensors were installed the trailering program recognized them and the set-up was pretty simple.

Got my new 3500 Denali last week and picked up the extra two sensors I need for my horse trailer on Monday. Took the trailer to the tire shop and didn't take long to figure out that the OEM stems are too small. After talking through some of the options others have taken as well as another one they threw out, decided to order the new/revised valve stems from Nichols. I also like that they're metal stems and not plastic. 

 

Taking the horses on a trip next week, so I'll get the sensors installed when we return. Hoping that everything else will go smoothly (programming, etc.).

I ordered the NAPA valve stems and my GM trailer tire sensors should be here today. I am hoping the sensor will if NAPA valve. I’ve already moved the receiver out from behind the license plate for better reception.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      By Black02Silverado · Posted

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
