- 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 ;-)

Ask the Experts about this TST Accessories and Parts

  • 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.

  • 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 Tire Pressure Monitor Sensor TST-INT-S1 Be Used On Different Wheel?
    The Internal Tire Sensor for TST TPMS Systems - Qty 1 # TST-507-INT-S1 can absolutely be removed and used with a new tire/wheel. It is mounted with a simple hose clamp/worm clam that is able to be loosened, removed, and reinstalled. The sensor is rated for a battery life of 5 to 7 years, so as long as you have battery, the sensor can be used and will function well.

  • 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...

  • 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 for Both a 2008 Jeep Wrangler and a Boat Trailer
    The best solution for you with both of these options is to use the Color Monitor for TST TPMS Systems # TST-507-D-C and the Internal Tire Sensor # TST-507-INT-S1 for each tire on your 2008 Jeep Wrangler and each tire on your boat trailer. This allows you to leave the OEM tire sensors on your Jeep and will protect the sensors mounted on your boat trailer from the water when you launch your boat.
