TST 507 TPMS (Cap, 6 Sensors)

Works great and held up well after 1 week use on my boat trailer transporting it 1500 miles. Shows temperature and pressure and installation of the repeater was easy after buying another male trailer wiring plug to fit into my spare female receptacle so it had 12 volt power. I purchased the plug at my local trailer dealer and wired it up so that it’s easily removed when the repeater is not in use. I used plastic wire ties to attach the repeater on my trailer frame just behind the hitch. The battery doesn’t last very long, about 4 hours, but I leave it plugged in during use and that works well. I like how you can remove it from the vehicle and take it with you to adjust the tire pressures to get an instant reading while adding or removing air, then place it back in the vehicle to monitor everything under way. I have another 4 tire monitoring system for a trailer I sold but needed a new 6 tire system for a new trailer and this particular system is highly recommended and well worth the piece of mind. It’s not cheap but I wouldn’t go without a TPS, and this system is fantastic. I had a nail in my tire after 500 miles but thankfully it didn’t go through the tire, didn’t leak air, and I was able to monitor the situation the rest of the 1,000 miles using this device. I did an extensive amount of research before purchasing a TPS and this one is great.

Simple installation and remarkable results. I installed the tire monitoring system so that I could feel safe knowing the tires on my RV were within safe perimeters. After installing I took it on an 800 mile road trip and everything performed flawlessly. I was able to monitor each of the four RV tires temperature and pressures and without any connection issues. It gave me peace of mind and all the reviews saying this system performed better than other is 100% true. My truck already has a factory monitor system but if it didn’t I could have also added the monitors to the system. It’s important to know the pressure and temps in trailer tires to prevent a damaging issue before it occurs. This system provides that and with no loss in signal. The monitor display switches between tires and it rechargeable through a ubs cord or can stay hooked up to your usb port or with cigarette adapter. Price is reasonable for the quality and reliability of this product. I found the setup to be easy and you can also find many videos on YouTube to aid. Overall this company gets my vote and I will recommend it to my family and friends.

I loved the color monitor and the ability to set every tire independently. I used it with my motorhome and towed jeep by buying more sensors. it caught a tire overheating due to a brake grabbing and saved the jeep from major damage if not total loss. My new rig has built in monitors but I passed the system on to a friend who needed a good system. Highly recommend!

These things work great. They do exactly what they’re supposed to do. Unfortunately in the last 18 months they’ve gone off 5 times. The first was for an actual tire puncture. The last 4 (including 2 at once today!) were because the weight of the sensor caused the valve stem to break. We’re replacing our valve stems with metal ones. If that doesn’t fix the problem, I’ll come back and give an update.

I purchased the TST-507 with 10 CAP sensors to cover my truck and trailer. At the time of purchase, they were just over $600 with the $55 coupon. Pricey, but so is a new wheel and tire and subsequent repairs from blowouts, so I felt the investment was justified.I have a dually truck and a 24' trailer with tandem axles (4 wheels). Based on other reviews we do not expect to need the repeater, however I will revisit this review if we do.NOTE: Be sure to follow the instructions IN ORDER for easy installation. They are easy to read, but I added some notes to the review that I thought would be helpful.Default setting is for tractor trailer tires (way too high) so the PSI & High/Low pressure alarms had to be set for my non-commercial equipment. DO THIS FIRST. Its nice they provide a guide to set the alarm levels - High alarm is 25% over PSI rating on tire, Low alarm is 10% under PSI rating on tire.Once that is done, refer to the graphic in the instructions (see picture) to determine which locations you wish to pair. I used a highlighter to color in the locations I was going to use. It came in handy during the pairing process. There is no right or wrong selections, just what makes sense to whomever is going to use the display. Make sure to identify the sensors using the supplied sheet of numbering labels.Now pair the sensors either using Option #1 (vehicle not needed) or Option #2 (vehicle needed). I had 9 sensors that paired with no issue using Option #1. The last sensor finally paired using Option #2.NOTE: When pairing a sensor, it is recommended to keep a distance of 2-3ft from the other sensors.Depending on your setup, some sensors are easier to install than others. If you are considering flow-through sensors, make sure you have metal valve stems and enough space to install them.The picture of my display is how it will look once all sensors have been paired, but not installed or in range. This is to show that ONLY THE LOCATIONS PAIRED will appear on screen. If you are missing a location, it did not pair. There are instructions to delete one location or all of them at once if you mess up or want a different setup.I checked the voltage on one of the sensor batteries before installation and they had depleted to just above minimum so I recommend bringing extra CR2032 batteries for the sensors.
