TPMS monitors your RV's tire pressure and temperature and sends real-time info to a wireless color monitor. Tire sensors run checks every 12 seconds and send alerts to monitor. Presets let you monitor up to 4 separate vehicles or orientations.

Specs:
This TST tire pressure monitoring system monitors the pressure and temperature level of the tires on your RV, motorhome, 5th wheel, motor coach, or trailer. The system utilizes sensors that attach to the valve stems of your tires. When a tire sensor detects an anomaly, it will wirelessly transmit an alert to the included digital color monitor. Your monitor will emit flashing lights and an audible alert to notify you of an issue, and it will display details regarding the anomaly. A booster is included to strengthen and amplify the signal that the sensors are sending to the display monitor.
Initial Setup
The TST TPMS is easy to set up and includes all mounting hardware and tools for installation. First, assign the tire sensor positions through the monitor's Learning Mode. Label each sensor with the corresponding numbering code sticker so that you know which sensor is programmed to which tire position. When you are setting up the sensors make sure the one you are programming is at least 2' away from the other sensors. Otherwise the other sensors will interfere with the sensor you are attempting to program. Once the tire sensors have been recognized by the monitor, attach them to the valve stems of your vehicle's tires. Next, install the booster and connect it to a 12-volt power source on your vehicle or trailer.
Use the included suction cup holder to mount the color monitor on your windshield so you can monitor your tires while you drive. You can also use the included rubber, non-slip cradle mount to set the monitor on your dashboard.

Multiple Wheel Layouts
You can program multiple layouts into the monitor, and you can scroll through each setup on the screen. This system can support up to 4 tire layouts and up to 38 tires total. Make sure to set your high and low pressure alarms for each layout that you are using. Some examples of popular layouts are shown above.
Tire Sensor Installation
Note: To inflate or deflate a tire you must remove the sensor.
Booster
The booster - or repeater - amplifies the signal strength that the sensors send to the monitor. Booster installation requires a 12-volt power source. It is waterproof and can be mounted inside or outside your vehicle with the included mounting hardware. On a trailer, you can mount it in the battery box in front of the propane bottles. On a 5th wheel, you can install it in the house battery bay underneath the overhang. You will want to place it below the bank of mirrors so they don't bounce the signal back and cause the system to malfunction. On coaches with towed vehicles, you can install it in the back battery bay. The power draw is so minimal that you can leave the booster installed without running the battery down. If you decide to unhook it for storage remember to reconnect when you are ready to hit the road. A red light on the repeater indicates that the unit is connected to power and operating correctly. Repeater installation is required for warranty compliance.

The tire sensors didn't work well on our aluminum duels. The weight of the sensor caused air to leak, especially on the inside wheel with a long stem. We replaced them with sensors that go inside the tire on the rim. No problem since. For some reason we couldn't get a refund so I gave the set to a friend.
I love ther product but have noticed one curious issue. When inflating the tires to the appropriate pressure as indicated on a tire gage, the corresponding pressure reading on the TPMS display is 8-10% low , eg., 61 psi per the gage reads 57 on the display. Three different hand-held gages produced the same result. Both flow-thru and cap sensors reflect the same on my primary vehicle (Sprinter 3500 w/dual rears) and the jeep I tow.

No change. Even with new batteries in the sensors, the display reads consistently 8-10 low compared to hand-held guages.
overall a very good system for just about anything from your 4 wheel vehicle to an 18 plus wheel tractor trailer.
I did find that the system was measuring somewhat different than my gauge, but it is very accurate to the system and consistent..
A little disappointed in the screen.. badly fades in sunlight and is not visible with polarized glasses on.
the screen is a bit small but I dont think larger would be better. It is very easy to read the numbers so bigger may not be better.
Overall I would recommend this system to anyone who is looking for a reliable tire pressure / temp display.

system works well.. have had no issues other than pressures dont always match mechanical numbers.. need to have a psi standard to match too.. Only one regret and that is that I should have gone with the pass through option.. Which just today my kid brother ordered his based on how well my current system works..
Sensors register pretty quickly after powering up display and the pressures displayed matches my gauge with reasonable accurately. The temperatures registered do not appear to be indicative of tire temperature and only in the ballpark of outside air temperature, so of low value to me. If alarm condition present the audio alert is plenty loud so won't be missed. On my 35 foot Class A, the transmission distance worked fine even without the booster when TPMS batteries were new. After 6 months of so the transmission distance decreased when not using the booster but fine with booster so I recommend installing the included booster even if you don't need it at first power up. Programming was easy. I recommend for piece of mind and would buy again.
The item was 6 days late, due to post office error.
2021 was the year of upgrades for my 2016 Fleetwood Flair 26D. It started with a TST 507. I really like this product! I'm not going to say that keeping tabs on the temp and pressure of my very expensive tires takes my eyes off the road but it sure does give me a sense of safety that makes driving, especially on highways, with my family onboard much more enjoyable. I'd buy another that's for sure! Kudos to the warranty and tech support process too after a failed sensor. If you're looking for a great product backed up by an ever great company, look no further.
Makes me feel so much better knowing my tire pressure at all times. They work all the time.
Easy setup and works as advertised. Installed on our Winnebago Vista LX 35F. Impressed with the clear color screen and the spare o-rings for use later. The 2 different holders for the main unit gives you options on where to place it. Charger cable and Adapters were also provided.., most times you have to buy these separate... this was a complete package!
Works great! On initial setup I accidentally (operator error) had the upper pressure limits set too low. It was a good test of the system when driving on a warm day and the temperature and pressure on the tires increased as normal and set off the alarm due to setting the upper limits too low.
Nothing but trouble with these sensors. I have had 3 go bad and replaced under warranty and now 2 more are bad. Connection to the screen is hit and miss, even with the repeater. Actually had one fly off while traveling also. Had one become loose and was letting air out. All had the jam nuts on.
GREAT product/service/pricing. VERY helpful to resolve an issue with the rubber valve stems with 6" valve stem extentions on my Class B Sprinter.
Ordering process was fast and easy. Delivery was fast. Installation was very easy. Pay close attention to every step on the pairing process. I somehow kept forgetting the very last "Go" step that lead to a little bit of frustration...... YouTube videos are sometimes incomplete and not all are created equal is all I'll say.
The system was very easy to set-up. The only issue I have had is that on a rare occasion the alarm goes off for a high temp or low pressure. I stop and check out the identified tire and find nothing wrong. I turn off the unit and then turn it back on and everything is fine.
They have worked well. TST’s customer service is great! We had a bad sensor after about 6 months and they sent a replacement overnight to our campsite at their expense. Exceptional!
Having not been able to travel, since I purchased it a year ago; I am installing now; before a major road trip. I had to replace all the sensor batteries; which were depleted.
Good product great service. Had a slight problem with set up, my fault. Called customer service and a very friendly and knowledgeable person walked me through the process. Great service.
Great product based upon reviews. Have not set up with our rv; just received yesterday. Great price/fast delivery from etrailer. Have purchased other items from etrailer. Great service so far.
Going on a 1100 mile trip to Oregon. Just the girls. Now we will know our tire pressure. Was easy to install from the instruction videos. Worth the value for safety.
I am stationary at this time but based the purchase off of my daughters experience with this brand. I have another brand and am not satisfied with it long term

The product very consistently reads 8-10 low on the display versus separate analog and digital tire guages. It is annoying since underinflated tires are dangerously prone to overheating and blowouts. I have to keep checking with a separate guage each morning and evening while on the road. I had a Gen 1 TST sensor and display B&W that operated perfectly. This one is less that perfect.
