Watch the video on programing. It's so much easier. So happy I got this system. I hadn't checked my tire pressure in over a year. 15 pounds low on all tires. Not any more. So much safer now.

- TST-507-FT-4

Pretty good product. Setup was a little cumbersome but I got through it with the included directions. It is meant for an tractor trailer with many axles so that is annoying that you have to cycle through all the extra tire locations during setup but in the end it works well.

- TST-507-FT-4

The tire monitor seems good. The directions were not very well organized and left as many questions as instructions. The monitor connected easily and seems to stay connected in my short time of using so far. Caution: I did not realize when I bought this that rigid metal tire stems are required. Rubber ones are not stiff enough to support the weight of the monitor. I had to spend an additional $80 to replace the rubber stems with metal.

On a trip a couple of years ago, we had a blow-out on one of the tires on the travel trailer. I have towed trailers for 40+ years, both cargo and travel trailers and I have always been able to detect when something was amiss. This time, however I was shocked when I had no idea that a tire blew until I was flagged down by a passing motorist. It was just luck that the trailer itself was not damaged. I decided to purchase a TPMS. The system installed easily. The repeater transmitted the data without problem to the in-cab receiver. The rechargeable in cab receiver did not require recharging except at the end of a three week trip and even then there was plenty left. I did have some problem understanding the instructions on how to program the unit, specifically, deleting un-needed axles as this unit is made with 18 wheelers in .Once I got the hang of it, things went smoothly. I will come back to report any issues, but for now it's a 5 star for performance. No deduction for my problems on programming.

Love the TPM’s One problem was the contriful forse of the wheels made the units hit against the tire rims,, solved by installing metal valve stems. I covld have been told that

- TST-507-FT-4

These work very well. I placed the little monitor on top of the dash to easily check the numbers. One time we were in very cold temps and the pressures were down below the limit I had set--boy howdy, the alarm works well! Would I buy these again?? Yep. Thanks etrailer

Ask the Experts about this TST TPMS Sensor

  • Easiest to Install/Use Tire Pressure Monitoring System for Trailer Application
    The tire pressure monitoring system I would recommend for a "beginner" or anyone looking for the easiest to setup and easiest to use in general is the TST TPMS part # TST-507-FT-4. The reason I recommend it is because it installs easier by attaching to the valve stems (others mount in the tire), it's a flow through design which means you can inflate/deflate the tires without removing the sensors, and because it has a grayscale display instead of color which helps with the cost.

  • Difference Between TST-507-FT-4 and TST-507-FT-4-C Truck Systems Technologies Tire Pressure Monitors
    The only difference between the Truck Systems Technologies Tire Pressure System # TST-507-FT-4-C and the # TST-507-FT-4 is that the # TST-507-FT-4-C features a color display monitor and the # TST-507-FT-4 uses a black/white display monitor. Other than that, they're identical. I've linked to a product demonstration video featuring the # TST-507-FT-4-C.

  • Does TST-507-FT-4 Tire Pressure Monitoring System Provide Audio as Well as Visual Alerts

  • TPMS System for Dual Rear Wheel Motor Homes with Valve Extenders
    The TST TPMS for RVs part # TST-507-FT-4 is ideal for your situation. It offers 4 flow through sensors. These sensors will attach to your factory valve stems then your extenders can attach to them. This will eliminate the issue with the excess weight of the sensors being to great on the end of the extenders causing them to fail. This will take care of the 4 rears now for the 2 fronts use the Brass Tire Sensors for TST TPMS part # TST-507-RV-S2 which will give you the two standard front...

  • Does TST TPMS for RVs Sensors Require Balancing Wheels
    The sensors of the # TST-507-FT-4 are less than .1 of a lb which means they would not throw your wheel out of balance and would not require rebalancing. We also have not had any customers report back that they had to do this either.

  • What is Difference Between TST Tire Pressure Monitor Systems # TST-507-FT-4 and # TST-507-FT-4-C
    The two kits you mentioned are basically the exact same with exception being the color of the display. The # TST-507-FT-4-C has the color display that puts the alert messages in red if there's high or low pressure as well as temperature whereas the gray scale # TST-507-FT-4 would display everything in the same gray-like color. Either kit works great on rubber valve stems. For the second trailer you'd need additional sensors with # TST-507-RV-S4 and you'd be able to use it with the same...

  • Will TST TPMS for RVs TST-507-FT-4 Work Correctly With Rubber Valve Stems?
    The flow through feature of the TST TPMS for RVs - Grayscale Display - Signal Booster - 4 Flow Through Tire Sensors # TST-507-FT-4 will still work on rubber valve stems, though TST does recommend that metal valve stems are used with these sensors. You will need to use the included booster for the system to work properly. I included a video of the # TST-507-FT-4 for you to take a look at.

  • TireMinder Pressure Monitoring System For 35 Foot Motorhome
    The biggest difference between a Tire monitor pressure system for a trailer and a motorhome is the sensor range. Systems that come with a signal booster are normally compatible with a motor home. The TireMinder TPMS for Dual Axle Trailers - Solar Powered with 4 tire sensors part # TPMS-TRAILER is only designed for single-axle trailers up to 25 ft long so it's not going to be a fit for your 35 ft motor home. For your motor home I recommend TireMinder TPMS for RVs - LCD Monitor - Signal...

  • Will the TST Tire Pressure Monitoring System # TST-507-FT-4 Work on Un-threaded Valve Stems?
    To answer your main question, yes, you can have the valve stems changed out to ones that will work with your tires and the TPMS system. I recommend going to either a local RV/Trailer Maintenance shop or your local tire shop; either of these spots will be able to make these changes on your trailer tires. You could even purchase the stems in advance and have them installed at one of those locations. In order to choose the correct stems, you'll need to know the maximum PSI rating on your tire,...

  • What is Max Safe Tire Temperature
    The typical tire should run about 158 degrees (Farenheidt) once you get going down the road, but this can vary greatly depending on the weight of the trailer, how fast you're traveling, and also driving habits. So while 158 is probably "normal", it isn't really a standard to try to stay at. I will say that you do want to avoid hitting the 167 mark as that is usually when problems start to arise when you go over that. 200 degrees is when you need to stop and check things out. If you have...

  • Recommended TPMS System for 2005 Ford F-350 Towing Fifth Wheel
    I'd recommend a TPMS system from TST, Truck Systems Technologies, because they're highly rated by our customers, they work great and their customer support is outstanding. To keep costs down, I'd recommend a system going with a system that used a grayscale monitor, versus the color. If you're talking TV's, color is the way to go but for a TPMS system a grayscale monitor would work just fine. I'd go with the basic # TST-507-FT-4 system, then add 4 additional flow through monitors, using...
