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!

The TST may well be among the best available. My rating is closer to 5 stars than 4, but I am not willing to give the product full marks.Lesser priced items had too many reported issues for my comfort level, and one I had purchased did not have the range required for use with a decent sized fifth wheel. I took the plunge on the TST. It worked fine right out of the box. Tire temperatures seem plausible. Tire pressures were mostly within a degree or so to other trusted sources, but one sensor seems to be off by a few degrees. Same with the tire pressures. While close within one PSI or so, not all sensors agree with a trusted calibrated pressure gauge. This does not make the system unusable, but is a little irritating at this price point.It'd be nice if they could be field calibrated.I did use the range extender and did not test operation without it. It can take a little time for the signals to be picked up but seem to hold well once acquired on a 35' trailer.It would be a lot better if the display be configurable to match the tires being monitored instead of having the generic and very busy display. This could be readily accomplished with some creative programming and perhaps a different more modern display. The display seems to work well enough and has good visibility in most lighting conditions.I would prefer the caps have a lower profile to further reduce chance of damage. Perhaps that would only be a serious concern in off road conditions.
