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)

so easy to set up works great easy to read display fits up under rear view mirror

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.

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.

Highly recommend! We are traveling across the country with a 5th wheel and this has alerted us twice to tire issues! Super easy to install and works wonderfully!!!

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.

So far these have worked great! They actually notified me a week ago that one tire was low. I went out to look and it wasn’t obviously low, but there it was, a large bolt straight through the middle of the tire. I was able to go to my local shop and have it fixed same day. Had I not had the sensors, I probably wouldn’t have seen it until it was a much bigger issue. Great product!

Amazing tire pressure monitor.. this is my 2nd purchase. Augments the internal one but provides exact psi and temperature, if you tow. Super readable monitor at a glance. I particularly love the solar charging which offers excellent battery life, but have backup charge plug for winter when battery power can become low. Very accurate system. Easy to install in less than a few minutes. I also appreciate the slide in/out window bracket mount. Advertorial value!

Advertised for RV use, but would not update / stay connected in the 40 foot run between my trailer axles and truck cab. (32' travel trailer, short box F-250) Otherwise would probably work well for a regular vehicle or shorter trailer.
