TPMS for Olly

[Against The Wind]

Hi friends. Thinking of adding a TPMS to our Olly sometime in the near future. Would like your valuable opinions on what to look at and what to stay away from. Yes, mention brand names, please. 😁

We have used this system for several years and are very happy with it. I cannot imagine towing our Oliver without it.

What we’ve used for the last 9 years.  Works well, no issues.

There are a ton of different brands - just type in "TPMS" on Amazon.  Also, do the same on YouTube to view many different brands as tested by "professionals".

Just about all of these do the same thing while having slightly different monitors.  

I would tend to stay away from the "cheaper" brands and would also question what am I getting for my extra money on the more expensive brands.

Simply put - this is NOT new tech anymore other than those that are starting to integrate the trailer's TPMS with that of the tow vehicle.

We've used the TST system for many (10+) years. We replaced the stock rubber valve stems with steel ones first. (These fit our 2022, YMMV: https://www.oreillyauto.com/detail/c/xtra-seal/tire---wheel/tire-valves---caps/tire-valves---cores/aede909cf322/xtra-seal-bolt-in-valve-fits-rim-hole-diameter-5-8-inch/xts0/17428 )

Definitely get a TPMS, regardless of brand.

The TST system was the first purchase I made before we picked up our Elite2 in Tennessee in 2022.   I wouldn't consider towing a trailer without some tpms on the wheels of the trailer.  I have eight sensors and extra batteries.  Four on the tv and four on the trailer.  I carry a ViAir air compressor also to air up as needed.

Again - 

Many times it is cheaper, when buying the initial setup, to get a couple of extra sensors - one for the spare tire on the Ollie and one for the spare tire on the tow vehicle.

These extra sensors will save you a bunch of time (in checking the air pressure in those spares) and provide an extra if you were to have a "problem" with one of the main sensors.

Our Tireminder TPMS system has worked well on our Elite II for the past 2+ years.   I mounted the booster under the rear dinette seat, with a "hard wire" connection to an unused slot in the 12V fuse panel, which is within inches of the mounting location.

We use the factory TPMS system for the tires on our 2019 Tundra tow vehicle.

I thought of getting extra sensors, but went with the ViAir compressor to just air up those spares if needed.  Since there's a tpms system built into the tv, I could just move one from the tv and put it on the trailer.  Maybe overkill to have duplicate tpms on the tv, but if that happens, I could then buy an extra sensor to replace what I used from the tv.

Of course you can do this - but

Many times those spare tires are not easily accessed.  In the Ollie you either have to purchase a valve extension or basically remove the spare in order to simply check that spare's pressure.  With my F-150 I would have to lower the spare from its position up under the bed of the truck before I could check its pressure.  The extra TPMS sensor usually saves me the effort of dealing with both of these "problems".

Thanks for all the timely responses, friends. Your suggestions will be closely regarded when the time comes for this upgrade.

Search the OTT Forum for 'TPMS' to get these suggestions and so many more. 🤣

This subject has been covered 10x! A small few of us, would not mount a sending device on a tire fill valve, there are issues! Given this thought, you may want to consider a professional installation, e.g. consider this thread, just started a few days ago...

My Savana van has built in tire pressure sensors and dash display monitor, but that TPMS system will not alert me if there is an on-going issue indicating a tire going flat or wheel overheating. If upgrading to metal valve stems to accommodate a secondary TPMS system, it is important to know that replacements are vehicle specific to ensure proper fitment to the stock wheel sensors. I acquired a set for the van, as shown below, and had them installed at Discount Tire for a nominal fee.

We went with a “cheaper” brand.  We have had it a year and so far are very happy with it. I would at least say cheaper is better than nothing at all in the case of a TPMS.

Ts t  continues to be our choice.

Great service

I don't have a 'shop' space or much in the way of equipment. Also, my TV came with a TPMS for the 4 tires (not the spare). I have some questions:

- What's involved in the installation process?  If a professional install is recommended, where does one go to have this done? 

- Are there any issues with adding a TPMS to a vehicle that already has one? 

- How much will an installation range in cost?  

Thanks to original poster, as this has been on my list of possible upgrades.

If you go with TST the install process is simple.  It does not interfere with your TV system as it uses its own monitor (display).  You simply put a battery in each sensor, screw the sensor on to the tire stem, then configure the sensors on the monitor (following the instructions).  Done.  We’ve had ours for 9 years with no problems.  I’m sure the other TPMS’s are similar.  Mike

TPMS sensors are user installable if you purchase the sensors that screw onto the valve stem. Internal (to the tire) sensors require professional installation. You will also need professional installation if you need to replace rubber valve stems with metal. While some have good results without switching the stems, my TST flow-thru sensors require metal stems (per the TST instructions). After a shop replaced my rubber valve stems with metal stems, I installed and calibrated the sensors following the instructions.

We only monitor the four Ollie tires.  We carry a Dewalt 20V air compressor.  Should we have a flat, the Dewalt is handy to top off the spares if low.  Of is we get into the two Ollie tire losses, we can run with three trailer tires with the lonely one pumped up to 80 PSI.  I like this options system.

The other advantage is that I only have 4 sensor batteries to change, and since I purchased spare sensors, I have spares to boot.

I have TST cap sensors on the four trailer tires and four TV tires, as well. Up to a couple months ago, only trailer-related tire issues have occurred requiring attention to flats or valve stem leaks in the past five years. However on a recent trip a slow leak was detected at a rear tire on the TV, a screw puncture was found. My TV has tire pressure readout, but no alert system and thus, so thankful I had sensors installed. I was able to repair the tire before further damage incurred due to under-inflation in tow.

You raised a good distinction. 

Our 2019 F-150 Lariat has a stand alone TPMS.  It will give me a tire pressure warning light on my dash.  The light for sure gets my attention and I can then change the screen to see which tire or tires are being alarmed.  For a 2019 Ford F-150 Lariat FX4, the factory recommended cold tire pressure is typically 35 PSI.  For this series of Fords the warning is set by the factory at 25% below the Ford recommended tire pressure or 26 PSI. 

When highway interstate towing Ollie, I run my Nitto Recons at 42 PSI.  I had not thought about how far down the curve Ford TPMS alarmng at 26 is vs my 42 psi set point.  With 8 seasons on my Ollie TPMS, it is not something I would now invest in.  But with your distinction in mind, when I replace the Ollie TPMS I'll for sure go with one that gives me better coverage on my truck monitoring as well.  I'll also look into if I can change the alarm 26 psi set point on the truck as well.

Thanks
