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 flow through sensors that attach to the valve stems of your tires. The flow through design lets you inflate or deflate your tires without removing the sensors. 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 it is not necessary remove the sensor. Simply unscrew the cap.
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.

TPMS system works great, customizable alarm settings for both pressure and temperature. Only complaint is that the sensors are off by a psi or two compared to a tire gauge, but once figured out, it’s no issue.
Traveling last season, had some irregular readings, so put fresh batteries to start this season and readings were consistent. Through the valve airing is much simpler. The constant readings of temperature and pressure reduces stress levels.
I had trouble getting the sensors programed at first so I called the tech line and they help me programing all of the sensors in no time. I now feel more reassured pulling our 5th wheel Cardinal now that I can keep all the tire pressures monitored.
The TPMS is an excellent product and recommended to anyone who pulls a trailer or towed vehicle. The flow through sensors are very convenient. This is my second TPMS by TST and I was very satisficed with the performance. The color screen is far easier to read in daylight. Programming took me a while as I am not to comfortable with electronics. After all was said and done, take my advice from a retired Hwy. Patrol Officer, Your safety is number one.! Don't leave home without one.
The tpms on my trailer tires have been wonderful. Last summer one of the tires had issues and I wouldn't have known if it wasn't for my tpms. However having the heavy weight of the Tom's sensor on the valve stem was causing the stems to tear. So I had the tire company install steel stems and I have no problems now. So recommend steel stems with this system.
Purchased the TPMS 10,000 miles ago. Has performed faultlessly and provided a sense of security never experienced in forty years of traileriing.

Continues to work faultlessly after another year and thousands of miles of service.
Find a good video and watch it closely, maybe several times. Installation wasn't too bad. Love the silicone stand that comes with the unit, brilliant idea! Placed it in far left corner of windshield so it doesn't block the view but is easy to see (and hear).
I installed these sensors on my Montana 5th wheel about a year ago. They have been very reliable and give me additional piece of mind while traveling. I had one tire blow out during this time and the system alarmed immediately. Also, once charged the monitor battery last for quite a long time allowing you to unplug from the charger and move the monitor around the truck cab for the best visibility during changing light conditions.
Have had these for a year now and they work great. The only reason I didn’t give 5 stars is because one of the flow through sensors had rough threads and is very hard to get started onto the valve stem. I never have any connection issues on my 38 ft 5th wheel with the booster installed.

I’ve had and used this product for over a year now and am very happy with the performance. It performs exactly as advertised. I’ve had no issues. I do replace the batteries once a year so I’m not really sure how much longer they would last.
This product was hardly usable. The screen was not clearly seen in ANY hint of daylight unless you cupped hands around it to block the light which is impossible when driving.
The alarms failed to alert at all when temps reached 150-160 degrees which resulted in 3 tire failures in 2100 miles (the tire guy set us up for failure too) but we bought the TPMS system to be ultimately prepared and in control for towing the large 5th wheel. The unit did show reliable inflation numbers but the temps were showing 40+ degrees cooler than the temp gun we also were using and ultimately the high temps caused the tire failures. We are getting new G rated tires and ultimately will replace the TPMS system for something reliable.

I spoke with my TST representative, who had some comments and questions. The TST TPMS reports the air temperature inside the tire cavity. There is no way to use an IR gun to read internal air temperature, thus, the customer most likely read tread temperature, which should be substantially higher dependent on ambient air temperature and road surface temperature. An overloaded tire will run much hotter - as small as a 10 overload can cause a 20° or more increase in tread temperature. Because theyre not right there looking at your tires and the system, here are some troubleshooting questions: IR Gun: Is the IR gun calibrated? Was it tested again after this to verify its accuracy? How was the gun used while driving? The rig and tires: Brand and age of the rig? Is it properly serviced? Have the bearings been serviced according to manufactures specs? Have the brakes been serviced according to manufactures specs? Were the brakes and bearings inspected after the blow outs and eliminated them as causes of heat? Has the rig been weighed? Has the rig been been weighed at each tire position after being loaded to the maximum capacity and as it was ultimately used? Was the pressure in the tires set according to the tire manufacturers data chart for the weight of the heaviest corner tire position of the rig after being loaded for use? What is the brand, rating, pressure of the original tires that blew? Were these the correct tires for this unit, do they match the manufactures recommended loadweight rating? Were they driving in extreme outdoor temperatures? Were they descending a steep grade or multiple grades? If you can get back to me with some additional information, Ill provide it to TST.
Excellent product. I have a one axle trailer so knowing early when a tire is having a problem is critical. This monitor was easy to set up and has worked perfectly. I did not need to use the extension antenna...it reaches the cab of my truck no problem. Continues reading on temp and pressure. I went on a cross country trip and this product was well worth the money.

Great Product , over a year and several more trips. Had one alert when tire temp went above my set parameters.
Good product altogether. Easy to setup and get running. Once setup it synchronized with the trailer tires within a few minutes.
My truck already has TPMS, and I'm wondering if I can get it to synch with the TPMS monitors that are already in place in the truck.

Works well, occasionally one sensor s out temporarily.
You do a wonderful job! Customer service, the how to videos and keeping track of the product in shipment is second to none. Thanks very much for being a reputable business.
We are so happy with theTST tire pressure monitoring system we bought for our fifth wheel! We use it every time we travel and go camping, and it has not failed to work as promised. In fact, we were getting ready to leave on a week-long camping trip a couple of days after I had installed this system (which is really easy to do), and on the morning of our departure as I pulled our camper out of its port, the TPMS audible alarm went off! I had checked our tire pressures the night before, but somehow a screw had become lodged in the sidewall of one of our tires and I guess moving it caused it to lose air pressure. I would never have caught this without the TST TPMS system—at least not until we were on the road! So, yes, I highly recommend this great addition for safety and peace of mind while traveling!
The system( 4 flow through valves) has worked great for a year and approximately 7000 miles. We have it on a two axle 28 foot toy hauler with 10 ply tires. It warned us of a tire failure due to a sharp rock puncture while traveling on a gravel road and prevented any damage to the RV or wheel. I set the high pressure warning 16 psi above recommended tire pressure of 80 psi and on a 100 degree F day it sometimes sounds the alarm on one or both tires that are on the sun side of the RV. The tire pressure has never gone past 16 psi above set pressure. The color display is hard to see in the bright sun when placed on top of the dash board. This device has given me great peace of mind while traveling.
Highlights include prompt delivery, product arrived in excellent condition, and placing the order with Lori was efficient with all questions answered. A competitor offered the same product for less, but as a repeat customer, knowing that I can count on etrailer's excellent customer service including their extensive library of how-to videos and all documentation readily available, made the decision to place the order with etrailer easy.
When I bought these I didn't read the part about these required metal valve stems. I put them on and with in a 100 miles I had a tire loosing air, these TST sensors are to heavy for standard rubber valve stems. After putting the new metal stems on I haven't a minutes problem.
These read out pressure as well as temperature per tire, they do alarm when pressures drop,they areare worth every penny. I do recommend these for anyone pulling an RV or boat. Also you can purchase more of the sensors
The installation was fast and easy. The TPMS sensors are inaccurate and constantly send false information. I set all the tires at the same air pressure. While traveling I noticed several of the sensors sent readings that showed higher air pressure and higher temperatures. I pulled over and rechecked the pressures with my air gauge. all tires were at the proper pressure. The sensors are very inaccurate.
Bought this product for my single axle travel trailer. I use one for each tire, one on the spare, and carry a spare with me for just in case. I have an F-150 SCAB towing a 21’ TT. It usually takes about 2-4 minutes for the module to connect to the monitors On each tire, but after that the connection is solid. I have not found a need to connect the repeater, but your usage may vary.
I bought a TST TPMS based largely on all the positive reviews.
Easy to read colour screen.
I like the flow through sensors. At first I thought they may have looked like big gobs hanging off the valve stems but it isn't all that bad.
Shipping was slower than normal because package was held up for days at customs which was out of everyone's control so it was not etrailer's fault shipping was slowed this time.
Excellent product. Easy to set up and use. Verified accuracy with two other pressure gages. Very convenient to adjust tire pressure without removing sensor. A couple of items that could be improved: 1) The screen is hard to read in daytime conditions. 2) The monitor reads one tire at a time and takes about 10 seconds to scroll through all (4) tires. Too long to take your eyes off the road. Displaying all four tires simultaneously would be a safer option. Otherwise a very good product. I would purchase again.
installed om my Aluminum 24' gooseneck cargo trailer. No issues with signal. Signal booster mounted to gooseneck.
Works perfectly so far. The extender was necessary to reach my 5th wheel tires, but I had no problem fastening to the inside wall of the battery compartment. Really provides peace of mind on the road.
Great product for keeping tabs on your trailer tire pressure and temperature. Also bought metal valve stems for better support of the sensor weight.
Just installed. Easy process. Sensors reading within 15 minutes. Am using the booster. The manual makes no mention of the inline fuse. Haven’t traveled with it yet. Seems like it will work well. etrailer price was $200 less than in store at service center.
Do you have a question about this TPMS Sensor?
