Tymate TM8 Tire Pressure Monitoring System, Wireless Solar TPMS with 4 External Sensors & 6 Alarm Modes, Colorful Display, Easy to Intall on Windshield, Ideal for RV Sedan SUV MPV Truck (0-87 PSI)

This tire pressure management system is easy to set up. It's perfect for keeping track of what's happening when the temperate changes rapidly. My car's original TPMS system just turns on an indicator. This let's me see if I need to add air to keep the tires at their proper inflation. It's inexpensive insurance to make sure my tires last a long time and are properly inflated.

I have purchased three of these now, one for each of our three trailers. Over the years, we have had numerous problems hauling show cars and show donkeys on long trips. Several times, we have had major tire issues, which can be very dangerous and disrupt schedules. I purchased one, and it worked fantastically, so I got two more. It is very comforting to look at the display and know the tires are all inflated to the proper air pressure, and on hot days and know they are not overheating. A warning of a tire going down before it blows can save your life. I highly recommend these units; installation is easy, and the solar power is great if you forget to turn them off. There is no dead batteries.

I've had this in my truck for about a month now and it seems to be working well. The solar cell is keeping it charged, I haven't needed to hook it up to the truck's power supply. But it comes with a charging cord if you need it. Installation is straight forward and simple. My only complaint is the digital readout screen is small and not easily read while driving. If the screen had been larger I'd probably give it 5 stars. But I think it's still a good buy for the money.

I didn’t have high expectations, but this set was great. Super easy setup and accurate pressure readings.

Seemed to work OK at first but accuracy was not great. After setting all my tires to the exact same standard pressure, using three different gauges for comparison, I then installed the TPMS caps. After a few minutes, all were reading but at three different pressures. I double checked several times over a few days and always the same results. There is also a very major flaw with this unit - if it loses connection with the sensors, it locks the display at the last reading and gives no indication whatsoever than there is no signal. This is NOT acceptable. You could easily be losing pressure and think your tires are fine since the display is still reading pressure. This is a lawsuit waiting to happen in my opinion. I finally gave up on it completely when it simply quit working. One of the buttons seems to have collapsed internally and the display won't even power up.

I really dig this. Using on an FJ cruiser that didn't have a TPMS system. The battery life on the screen portion is amazing. I thought I would have to turn it on and off for use but I leave it on all the time and it has never even dropped a single bar of power. Takes about 30 seconds for it to find all 4 tires when it gets powered on. I love it. Small and very functional. It is very accurate too. Digital air guage said 44psi and that is exactly what this device reads. It has already alerted me of a flat too so I really dig it.

Three work fine, one makes me think l am having a flat by leaking.

I haven’t had them for long, but so far, so good. It was very convenient to have an idea of what was going on with my trailer tires. The sensors were consistently 4 psi higher than the other tire pressure gauges I used to verify. I had no trouble with battery power on the monitor.
