I purchased this style of TPMS because I feel it’s the best aftermarket version- No bulky valve stem heads to fiddle with or grow legs/ wings. Plus, it shows temps. I needed help with programming it and the very knowledgeable gal who helped me, picked up on the first ring! The display is bright and visible thruout the day and it comes with a repeater that is simple to hook up, although my 26’ class C doesn’t seem to need it. It even has a position on the display for the spare tire, or the 7th tire, in my case. I like the dashboard cradle it comes with, because I can easily hide the unit when parked or storage.
In the year I’ve owned it, we’ve only gone on 4 trips but it’s worked really well each time.
1 drawback might be that the tires need to be dismounted to install the sensors. I had not done proper TPMS research at the time I’d purchased 7 new tires for my rig, and wound up having to go back to the tire shop to have the sensors installed, but hey, live and learn! Well worth it tho. This design leaves your valve stems looking clean/ stock. I put the kind of caps that have the little ball valve at the top, so filling the air can be done with 1 hand. If you are considering new tires for your vehicle, that would be the time to get this system! Another concern might be to know how long the sensors last before needing new batteries. But overall, very happy with my decision to go with this brand and design. One friend of mine has the kind where you have to remove the sensors to fill the air, and it’s a pain. He was looking into the passthru style, but those are also straining on the valve stems, which leads to leaks because as the wheel spins, that big ole sensor is causing drag on the valve stem.
Not mine! Easy Peasy.


I chose TST due to their excellent reputation and customer service. I chose etrailer for their prompt service and good prices. The TPMS system set up easily by following the instruction manual. The installer followed the TST instructions as well (they have done this before) and everything worked great once the work was done. I'm hoping to get the 4 years (3-5 estimated) of battery life out of these internal sensors. The display sits nicely on my dash in the supplied cradle. It will provide an extra degree of peace-of-mind while driving my RV full-time.



Such piece of mind! As I drove through the mountains this summer and cooler weather then down to the desert for much warmer, it was great to be able to keep track of my inflation pressures. Its great for tire wear, fuel efficiency, and most of all safety. The system continues to work as advertised.


This TPMS is very good. The customer service offered by the manufacturer is exceptional. Our monitor failed and they replaced it and helped me reprogram with the internal sensors already mounted. Would not hesitate to buy again.



This TPMS is very sensitive. In California, where temperatures can be warm especially in the central valley, we can set the alarm off at 70 degrees and 50 miles of travel. I dont know what professional truckers do in the same circumstance. It is not advisable to slightly deflate tires, but that is what weve had to do.


I purchased 6 tst internal sensors for our RV with the color monitor. I also purchased 4 flow-through monitors for our jeep, which we tow. The products are awesome and saved us from destroying tires on the RV. On RV’s with dual tires in the back, the inside tires get extremely hot in high summer time temperatures. The sensors taught us not to drive when ambient temperatures are 95 or higher. We have read where numerous RV’ers have had catastrophic blowouts on inside dual tires and our tst sensors allow us to avoid those dangerous situations. We absolutely feel the product should be installed on all R’s and trailers.


It’s been a year, so far so good. They have paid for themselves twice now. Only complaint is an occasional glitch/ interference which sets off the alarm periodically. Other than that works great and the temperature and pressure alarms are customizable in case you deal with rough or challenging environments.


The order was correct and delivered on time. The TST TPMS was easy to set up once the tire shop install the sensors in the tires. The monitor is colored and easy to read. The TST TPMS was expensive. If you have ever had a blowout that caused damage to your rv, the cost of the system is will worth it.


Great product from a great company. This is my third time using this TPMS system. I've tried others but this one seems to work best, just get enough repeaters for your application.
It's actually easier and cheaper to buy this through etrailer and they take care of you keeping you updated on your order progress.


Great product


So far so good. Nearly one year with the internal sensors and all 6 tires report back very accurately to the monitor. Time will tell if the batteries last the 5 years I was told to expect from them. If so this system will be hard to beat for ease of use.



Still going strong nearly 2 years in


Always appreciate etrailers product selections and expertise.


Received my order quickly and in good condition. Very excited to get it installed and in use


Just installed this System in my RV , it’s awesome setup tire temp and psi rotates from each tire , I like it

  • TST TPMS System TST-507-RV-4 - Can I Swap Cap Sensors For Internal Sensors
    Yes, you can swap out your cap sensors for internal sensors and they will work with your current TST-507-RV-4 system. We offer the internal sensors individually with part # TST-507-INT-S1. Definitely a good idea if you don't want to have to worry about a sensor going missing. The internal batteries usually last at least 5 years.

  • Will Counteract Balancing Beads Damage Internal TPMS Sensors In TST TPMS System TST-507-INT-6-C?
    I reached out to my contact at TST and confirmed that the TST TPMS - Color Display - Signal Booster - 6 Internal Tire Sensors # TST-507-INT-6-C you were looking at will work perfectly fine with the Counteract Balancing beads you use in your tires. This system includes 6 TMPS Sensors but you can purchase additional sensors using # TST-507-INT-S1 if your trailer/RV has more than 6 wheels.

  • Troubleshooting A TST Internal Sensor That Randomly Turns On/Off And Gives False Readings
    If one of the sensors in your TST TPMS # TST-507-INT-6-C is randomly turning off/on and only reading 1 or 00 for the tire pressure that leads me to believe the battery is dying and not allowing the sensor to properly operate. The batteries are expected to have a 3-5 year lifespan, but there are instances where the battery could prematurely expire. If you were having issues with more than one sensor then it would most likely be a signal issue, but with it being just one it's got to be a...

  • 10 Sensor Tire Pressure Monitor System with Color Display with Repeaters
    For what you are wanting the best solution is the TST TPMS - Color Display # TST-507-INT-6-C which comes with a color monitor and 6 sensors. Since this can be used with up to 110 sensors you'd just need to add the additional sensors to get to 10. For additional sensors you'd want the part # TST-507-INT-S1 for each one individually and then for signal repeaters you'd want the part # TST-507-R. We do not have a hardwired solution that covers all of the things you need.

  • Battery Life of Tire Pressure Sensors Used on TST-507-INT-6-C Tire Pressure Monitoring System
    According to TST, once the repeater is installed, the sensors included with the # TST-507-INT-6-C will work within 5 minutes. My representative tells me that the expected battery life is 3-5 years, and once the battery goes dead, the sensor itself must be replaced as the batteries are indeed sealed and aren't replaceable.

  • Reliability and Battery Life of TST Internal Vs Flow Through Tire Pressure Monitoring Sensors
    According to my contact at TST, going with the internal sensor would have the following benefits: • Battery Life. The internal sensors can be expected to last 5+ years, versus about 1 to 1-1/2 years for the external. • Protection: By virtue of the fact that they're mounted internally, the sensors would be less exposed to the elements and damage from road debris. The sensors would also be protected from theft or vandalism. About the only downside to the internal sensors is that the...

  • Do Internal TMPS Sensors Require Any Venting
    The TST TPMS # TST-507-INT-6-C is designed to clamp around the wheel before you mount the tires. You won't need to vent any air pressure unless you overloaded the tire's max psi rating. With this style of sensor you wouldn't need worry about the type of valve stem either, like you do with a flow-through style sensor.

    Good question, so I reached out to the manufacturer, TST, regarding rotating tires for the TST TPMS - Color Display - Signal Booster - 6 Internal Tire Sensors # TST-507-INT-6-C.

Then select where you want to move it to, and you press the SET button and it is electronically moved. Or, you can...

    With the Grech Strada RV not really being that large you can just mount the repeater for the TST TPMS Internal Tire Sensors # TST-507-INT-6-C somewhere in the engine bay. A couple of self-tapping screws will easily mount this to an open space. I've attached an example of this below that we do quite often with a battery disconnect switch. If you were using these sensors on a trailer then I'd say it'd be best to try and get it as close to the end of the RV as possible to get the best connectivity,...

  • Can TST TPMS With Internal Sensors Also Use Flow-Through Sensors
    That is an interesting question, so I reached out to the manufacturer, TST, who said yes, you can use the flow-through sensors with the internal sensors. The reason why is that each sensor - the internal and flow-through - has a unique 6 digit code so they are compatible, so long as they are all the same 507 version. So for the system with the six internal sensors for your motorhome, and compatible flow-through sensors for your towed Jeep, you will need the following: - TST TPMS - Color...
