- TST-507-INT-S1

The sensor work great. I had the valve cap sensors and had trouble getting them to seal properly and kept losing air in one of the wheels so I decided to give these a try. They are a more complicated installation, but if you do any of your own automotive work, I'm sure you can handle it. all you need is a bead breaker in addition to typical tire changing tools and the proper socket or nut driver for the wormgear clamp and it takes about 15 mins per tire. The bead breaker I used is the Beadbuster 450, but there are less expensive options out there. Also, etrailer met all my expectations and sent the correct product in a timely manner.

- TST-507-INT-S1

These are great! I bought monitor and 6 sensors last year and put 5 on my 5th wheel (spare tire) and 1 on my dually spare last year. I bought 6 more for my dually this year. I haven’t had any tire issues yet, but it gives me peace of mind to be able to monitor both pressure and temperature. I choose the internal sensors so that I won’t have to worry about theft. Plan on buying more in the future for my 20 foot utility trailer. Left monitor unplugged for 6 months and it still had battery power left when I turned it on.

I have had the TST-507-INT-S1 for over a year. I have 8 censors. 4 on the truck and 4 on my bass boat trailer.I have had absolutely no issues with this product- My truck and boat will set without using for several weeks to 2 months before I travel- When I leave my home, I turn on the unit, plug in the USB charger and start driving-In about 5-10 minutes, all 8 tires are reading- One thing I like about this system, is that I can have 16 more tires without any changes or additional purchases of equipment other than the sensors for the additional tires. I own 8 different towable trailers, so nice to just hook up and go, knowing what my tires are doing- Highly recommend this product!!

- TST-507-INT-S1

These are so good! No valves to worry about snapping off and no valve attachments. Really am fond of these...

I placed this order online on a Friday. I noticed that the website stated that the order was not due to ship for a week even though the items were in stock. I called asking why there would be such a delay and was given what I felt was a valid reason for the delay. I explained that I needed the items and ask for any help that might speed up delivery. The next day, I noticed that the items had shipped and the estimated arrival date was the Friday following my placing the order. The items did arrive on the Expected delivery date! I do not know who interceded on my behalf but I greatly appreciate their efforts and the customer service that was provided for me. A great company to do business with and I will, again!

- TST-507-INT-S1

This product is very popular with RVers [online] Most have gave this product a very good review using the valve stem caps or the flow through sensors. I bought the bands that go inside the tire! I believe this sensor to be superior to the others due to the fact that I will not have to remove anything to add or remove air from the tire. Plus I will not have to worry about someone taking them off my wheels. I am looking forward to many miles of worry free RVing in the future! You might consider buying the TST system on etrailer individually instead of a kit; I found it to be cheaper and more custom to my needs! God Bless America like he does TEXAS ;-)

  • Why Does My Internal Tire Sensor for TST TPMS Systems # TST-507-INT-S1 Keep Alerting?
    I have a solution for you. I went ahead and contacted my tech at Truck System Technologies, and he said that the RV does not have to be in motion before the Internal Tire Sensor for TST TPMS Systems # TST-507-INT-S1 accurately reports the data. As far as your alarm issue, it often happens when the monitor is not set up correctly with the axles of your RV and/or trailer. In order to correct this, each tire must be programmed for the axle that it is on (the high pressure and low pressure...

  • Availability of 6 Internal Sensor Tire Pressure Monitoring System with Color Monitor
    For a system with 6 internal monitors and a color display monitor, use part # TST-507-INT-6-C. Ordering the parts you mentioned separately wouldn't get you all the necessary parts, as the repeater would be missing.

  • 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. This system works with up to 110 sensors so it is great for even the largest RV or RV and trailer combination. I...

  • TPMS Sensors for TST 507 System
    I have another option for you. As you may know, the TXT 507 systems come with valve-cap style sensors. There are not any non-TST valve stem sensors, however there is something better. The TST # TST-507-INT-S1 sensors install inside the wheel. There are two big benefits to that. First, they don't get stolen or lost, and Second they provide better internal tire temperatures readings. Heat is the real tire-killer.

  • 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...

  • Can You Add Additional Sensors To The TST TPMS 6 Internal Tire Sensors Kit TST-507-INT-6-C?
    I have a solution for you, however, the TST TPMS - Color Display - Signal Booster - 6 Internal Tire Sensors # TST-507-INT-6-C is not offered as a kit with 8 sensors. Luckily, you can add sensors using this: Internal Tire Sensor # TST-507-INT-S1. I confirmed with TST that this will work great with the 6 sensor system # TST-507-INT-6-C, which will actually work with up to 110 sensors. This TPMS system updates every 12 seconds to relay the tire pressure and temperature information to the...

  • Tire Pressure Monitor System That Uses Internal Sensors
    For internal sensors you're going to need to use the TST TPMS as opposed to TireMinder as TireMinder don't have internal sensors. For your application you'll want to go with the TST Kit # TST-507-INT-6-C and then you can add more internal sensors with part # TST-507-INT-S1.

  • What Type of Battery Does the TST TPMS Internal Tire Sensors Use
    The TST TPMS - Color Display - Signal Booster - 4 Internal Tire Sensors part # TST34FR does not use replaceable batteries. The batteries have an estimated life of up to 4 years. Once the batteries die, you'll need to replace the sensor using part # TST-507-INT-S1.

  • Will the Band Style TST TPMS Sensors Work with Factory GM TPMS for Trailers
    I do have an option for you but the GM TPMS uses a proprietary software, you cannot use another sensor with the program even if they operate on the same frequency per TST. I do know of many others who have run into issues with GM not offering a solution for the larger 16"+ wheels. Therefore, your best option for these larger tires is a standalone system for which I recommend the TST TPMS part # TST34FR which comes with a color dash monitor and four sensors.

  • Is the Repeater Installation Required for TST TPMS for RVs
    Starting with your first question, you will need to install the signal booster when installing the # TST-507-RV-4-C. Failure to do so will make the system unreliable. Since you have 6V batteries you will be able to power the booster. In order to get the 12V power, 2 of your 6V batteries will need to be wired in series. For your boat trailer, the # TST-507-RV-4-C will work but you will need to add a way to power the repeater. Since you will be submerging the sensors in water, I recommend...

  • How to Monitor Tires on 2018 Ford F-250 with TST Tire Pressure Monitoring System for Trailer
    The TPMS on your 2018 Ford F-250 are using their own system and it won't be compatible with the TST TPMS # TST-507-FT-4-C that you are using for your trailer. If you wanted to use the TST to monitor the tires on your F-250 as well then you'll need to install some TST sensors on your truck tires. You can either use more of the Flow Through Sensors # TST-507-FT-S2 (which comes with a quantity of 2 sensors) or you could mount the Internal Sensor # TST-507-INT-S1 on all 4 wheels but this option...

  • Recommended TPMS for 18 Wheeler
    The TPMS I recommend for an 18 wheeler is the TST TPMS for RVs part # TST-507-FT-6-C because it has a range extender and uses flow-through sensors which are both things you will need. The range extender will be needed as 18 wheels are generally pretty long in overall length and the flow-through sensors are needed because most dual tire applications use valve stem extenders and you'll need to install the sensor between the wheel and extender in order to get the proper reading.

For a set that includes 4 internal sensors, the monitor and signal booster you can get the # TST34FR. For a valve stem option there is the # TST-507-RV-4-C.
