Taking good care of your tires is important, especially as an RVer. We have always been diligent about tire safety, care and proper inflation. But until recently, didn’t have a tire pressure monitoring system (TPMS) on our RV. Here we review the TST 507 Tire Pressure Monitoring System by Truck System Technologies. We chose to go with 6 flow through sensors for our RV and 4 cap sensors for our tow vehicle. Keep reading – and watch the video – to learn more about the TST 507 TPMS. We’ll cover what comes in the box, features, and our thoughts.
Spoiler Alert: We like this so much, we featured it in our 2019 Holiday Gift Guide
Our Jeep comes equipped with an on board TPMS system. But of course, when we are towing it behind the motorhome, we aren’t able to monitor those tires. So the additional cap sensors allow us to monitor the Jeep tires while towing it.
We had been researching TPMS systems for a while, and this particular model was already on our short list. So when the folks at TechnoRV offered to send us this unit to test it out for ourselves, and share our honest review, we graciously accepted. Most of the time, we purchase the gear that we review. But occasionally, we do accept products gratis (or discounted). But ONLY if it is something we genuinely have an interest in and use for, is well-rated, and that we feel will be of interest to you – our audience. We never accept items that we would not have considered buying ourselves, after doing our own research.
About the TST 507 TPMS
The TST 507 is a Tire Pressure Monitoring System (TPMS) by Truck System Technologies. It remotely monitors the pressure or the PSI of your tires and temperature for optimal tire safety. This can be used for all sorts of tires on different vehicles such as RV, motorhome, truck, trailer, or car. Knowing your vehicle’s tires pressure is super important for safety reasons, but it’s especially important for an RV because we live out of our motorhome.
Using this device dramatically increases safety, and helps ensures proper tire inflation and temperature which can help reduce the risks of blowouts or other tire failures. You may have seen the sobering results of what can happen after a tire failure in our blog post and video “Where RVs Go To Die” after our visit to an RV Salvage Yard.
This is the only TPMS system (to our knowledge) that includes a color monitor. It is 3.5″ and weighs less than a half a pound. You can choose flow through and/or cap sensors for each tire. The cap sensor is very popular with those are looking for a low-profile sensor. The Cap Sensor can be used with metal or rubber valve stems.
What is included in the kit
- Color Monitor
- The Number of sensors that you choose
- USB/DC power supply
- Signal Repeater
- Rubber Dash Pad Mount
- Suction Cup Window Mount
- reporting of tire pressure (PSI) and temperature on the Color Monitor
- monitor can report up to 4 trailers/towables
- ability to customize each axle for high and low alert parameters
- cap sensor features a user replaceable battery (CR1632)
- sensors will auto code to the monitor
- theft resistant feature
- color monitor auto-scrolls through each tire reporting PSI and Temp
- GE Circuitry and well insulated sensors
My thoughts on this TPMS
After using the TST 507 TPMS system for about 4 months now, I have to say I am very impressed with this unit. The setup and installation was really easy. With the preset alert triggers, and ability to watch the data scroll through the display, I now have more peace of mind when driving our RV. This system has saved me a significant amount of time in checking tire pressure (and airing up as needed with our Air Compressor) before each trip. My only regret is not installing this system in our RV from day one! It would have saved me a lot of time in tire checking before and during trips.
How much does this TPMS cost?
The starting price for four cap sensor and flow through sensors is around $400. Prices vary depending on how you build your system. You can easily customize your system and add on more of either type of sensor as well.
As mentioned above, we have 6 flow through sensors for our RV plus 4 cap sensors for our tow vehicle. The regular retail price on this system comes in at around $700, for the unit, color monitor and 10 sensors.
However, this TPMS is currently on sale – see the Where to Buy Section below for more detail, and links to purchase.
Where to buy
We have a few suggestions for you. Click one of the three BUY buttons below to purchase your TST TPMS with Color Monitor, and choose your desired type and number of flow through and/or cap sensors.
CURRENTLY ON SALE – The best price available on this unit is from Mobile Must Have. They have a great price already, but with coupon code TST10RVL2020 you can save an extra 10%! That is the lowest price we are aware of anywhere!
The Mobile Must Have online store is run by our full time RVing friends Erik and Kala (of Livinlite.net).
They recently launched MobileMustHave.com which offers a variety of connectivity, technology, RV and safety gear. You can also buy from TechnoRV, another great online store for RVers, run by RVers Eric and Tami Johnson.
We recommend purchasing either from Mobile Must Have or TechnoRV as these are both companies run by full time RVers that we know personally, and are great to do business with. Both enable you to tailor a complete kit to your specific needs, especially if you prefer a mix of the type of sensors (as we have). Unfortunately, it’s not QUITE as easy or cost effective buying a kit like ours through Amazon, unless you only want one type of sensor. Their kits come with either flow through OR cap sensors, not a combination of both.
Use Coupon Code TST10RVL2020 to save an extra 10%.

Your System works good inless you have a blowout on your tire and then the reading stays the same as If nothing has happened.
Did that happen to you? Obviously THAT is not supposed to happen. Do you have the TST507 and experience a blowout and no changed tire pressure reading? Please share more specifics if you can – thanks!
We took our first trip this weekend with our Rockwood 2608bs equipped with TST system. # of the 4 tires read well but 1 keeps coming in high enough for alarm to sound on air pressure. It usually claims high pressure than all of a sudden will say there is a fast leak until settling in at a certain pressure. What would be the cause of this and how can it be fixed?
Hi Keith, First up, – that is awesome to know you set off with a TPMS system on your RV! Second, hmmm have not heard of that issue you are experiencing so cannot advise a solution unfortunately. Recommend you contact the manufacturer for product support. Here is there website: https://tsttruck.com/product-support – hope that helps!
I have been reading comments lately concerning the fact that after running the TST system, with caps on rubber valve stems, the caps will mark the accompanying rim. This due to centrifugal force tending to make the stem bend outwords, making the cap touch the tire rim.
I have a TST RV system. It certainly has performed well, but I, too, have noticed the rim marking.
I am not concerned about the marking, per se, but do have questions about the flexing of the stem necessary to make the marking and how much fatigue may be going into the stems.
Most readers of the above mentioned comments are running, not walking, to install metal stems.
I’m still not convinced that that is necessary, but do have questions of the stem loading.
We haven’t experienced any marking with the rubber stems on our Jeep (of course, we have the regular TST caps meant for rubber stems on the Jeep). Our coach has metal stems, and the metal stem (flow through) sensor caps. No marking there either. I suppose it would depend on the type of rim, the length of the rubber stem, and potentially the speed folks are traveling. From our experiences, I don’t believe metal stems are needed on your rims if they don’t already come that way. I imagine it would not hurt to have metal stems installed as an extra precaution, but don’t feel the urgency you are describing others have around this topic. TST might have additional insight, but the fact that they sell two different types of sensor caps is a pretty clear indication of what they believe the practices should be. In other words, don’t put flow through sensors on rubber stems, but the regular caps are probably fine.
Thanks for the question.
