TM7 Tire Pressure Monitoring System, Wireless TPMS with 4 External Sensors & 6 Alarm Modes, Colorful Display, Real-time Tire Pressure Monitor System, Ideal for RV SUV MPV Truck Sedan(0-144 PSI)

I like being able to see the tire pressure real-time. Installation was simple: plug the monitor into the 12v port, turn it on, place the sensors on the tire valves and watch it do what it was designed to do. Great price and great product that works well.

These work well and easy to install. The anti theft aspect is not very effectice. They give accurate readings so far over about a month of use. Yetvto see how durable they are but recommended so far.

Works great and easy to set up. I think one sensor reads a little low (1-2psi low) but its inexpensive and will alert if I have a low tire. Display is bright and plugs into 12v outlet no wiring plug and play

Overall, this is a solid tire pressure monitoring system and does what it’s supposed to do. In my testing, the readings have been within about 1 PSI of a manual tire gauge, which is accurate enough for everyday use. Setup was pretty straightforward, and the sensors paired without much trouble. The display is easy to read, and it’s helpful being able to see real-time pressure and temperature instead of relying only on the car’s basic TPMS warning light. That said, it’s not perfect. Like most external sensor systems, there can be slight fluctuations depending on temperature, and you’ll need to stay on top of sensor battery life over time. I also noticed that small pressure differences (1–2 PSI) can affect whether my dashboard TPMS light turns on or off, so it’s important to understand your vehicle’s thresholds. Overall, it’s a useful tool for monitoring trends and catching issues early, but it shouldn’t replace occasionally checking with a manual gauge. If you go in expecting that, it does its job well.

6/3/25 Update: By the way, it is SO GOOD, that I bought the solar versions for our other two cars. They all worked great EXCEPT (TOTALLY NOT your fault!!!), my wife and daughter (UGHH!!!)--my wife kept putting the solar charger in the car door pocket when she got through driving (I didn't know that she was doing this--I wanted to install it on her windshield, and she didn't want it "in the way"--WHICH IT IS NOT, up where you put the oil sticker!). So it became discharged (DUH), and my daughter drove the car with a slow tire leak. My wife ALWAYS notices things like that (but NOT precisely--she's often wrong [thinking it's kind of flat when it's perfect]), but my daughter RARELY does. So my daughter drove it with it COMPLETELY (or way too) flat. DESTROYED FAIRLY NEW MICHELIN TIRE!!! My daughter also never notices tire pressures you show, BUT YOUR BUZZER GOES OFF WHEN IT'S TOO LOW OR HIGH to prevent damage before it's too late. How do I know? She's called me while driving to ask me what the noise is. So yes, your system works PERFECTLY. Unfortunately some in my household don't. By the way, my daughter has made nearly straight A's since kindergarten, and has just graduated from hygiene school (DIFFICULT major), and passed all the boards. Her head just isn't into car details. AND my wife now GLADLY had me mount it on her windshield (she has NOT ONCE complained about it being in the way AFTER I did so), and she's REALLY glad to have it there now! Original review: Keep up the good work, guys! And thank you VERY MUCH! I bought one of these for my daughter's car (in May—it’s now late October, 2024), who is in college (and is really careless about things like this). How did it help her? As summer slipped into fall, all her tires went down in pressure a degree, then another, finally down to about 26 or 27 pounds each. Did she notice them going down? No—even though Tymate properly reported the pressures—she just didn’t glance down at it, although she’s always fooling with stuff all in and around the Tymate, because of her phone, and countless cosmetic stuff there. But once it got down to about 27 pounds, it started beeping at her, so she had to figure out what was beeping, and why, after which she told me about it, and came home for me to get her tires up to specs. Without this, she would have worn her Michelin tires (4 new ones this last summer) out early. (She's not spoiled--I have her buy them out of her waitressing money, to help with responsibility.) For some reason when I first installed them, one of the sensors was off by two pounds. I emailed Tymate through Amazon, and Tymate immediately rushed out a new sensor to resolve the problem. However our daughter is in school most of the time, and by the time she came home (school isn't far), somehow the original Tymate sensors were all perfectly reporting pressures in all tires. We have 3 old cars (including my daughter's car), such that all have those dummy TPMS (tire pressure monitoring system) notifications, by which I mean a single icon comes on, meaning that ANY of the tires may have too much or too little pressure. That's bad enough, but what's worse--you check all the tires, and they’re perfect, which means that one (or more) of the sensor(s) is/are bad--which one? Well, supposedly a tire shop can use their equipment to find out which one(s), but then you have to the tire dismounted from the wheel rim, the TPMS device removed from inside the wheel, a new TPMS installed, which also means you will have to have that tire balanced again. That stupid procedure costs significantly more than this Tymate system, and you STILL have no idea the pressure of any of the tires. So for a good bit less with Tymate, you ALWAYS know the pressure of each tire all the time (at least once you get to 12.5 MPH), and exactly which tire, and the temperature of each tire, because if the sun is blazing on some tires, while others are cool in the shade, it can vary the tire pressure by multiple pounds, but it also shows the temperature of each. So, my wife (correctly) noticed the tire pressure of one of her tires low. I fixed that, and bought a solar charge wireless version of these (can’t believe I didn’t do it that way for my daughter’s car—it can only be read where plugged in a 12V outlet). The wireless version you can mount wherever you want on the windshield. For me, I choose the extreme top-left corner, where it’s behind the visor (if down). (I moved the oil sticker to be below this.) Later my wife again told me about a tire being low, even though the Tymate reported correct pressure. So I manually checked the tire, and Tymate was reporting perfectly accurate information. I still had trouble convincing my wife—I explained about the engine up front causing the tire to appear lower…blah, blah, blah—I barely convinced her, but I’m thrilled to know all the time now. My own car was also giving the incorrect TMPS icon (which is barely helpful, and only if correct, which it’s not, so it’s a pain in the rear), so I got another solar wireless Tymate and installed it on my car. All my cars are Toyotas, about 200,000+ miles on them, all with perfectly running engines, transmissions, and virtually everything else. Some people really disparage not getting the Toyota brand TPMS, insisting that only Toyota’s are accurate. That alone is about double the price of Tymate BEFORE the expensive installation (for ONLY ONE tire, as opposed to Tymate being for all 4 tires), and you still only get the idiot icon. Such a blessing to have these Tymates! Oh…one more thing. With the wireless/solar Tymates, they are only designed to be mounted to the windshield, NOT your dashboard, therefore they have to be “stuck” in place. They come with 3M double-stick already installed in them, which you just pull the strip off and stick to your windshield. I did NOT want to do it that way for several reasons: 1. Windshield do need to be replaced, whenever a rock flies into it. So how do you then get the Tymate off? I’m not saying you can’t, but it may not be easy. 2. Perhaps you would later like to change to location on your windshield (e.g. I can hardly find a place to please my wife, and might she change her mind once installed?) 3. I might like to temporarily remove it, such as when cleaning my windshield. So I just cut some Velcro, to precisely fit on top of their 3M tape area, taped the “hook” (rough, scratchy) side on top of the (still covered) 3M tape on the Tymate, and the “loop” (soft, fuzzy) side to my windshield. Now I can easily pull it off and place it back on again any time I want. If I want to move to another windshield location, I just cut a new “loop” side for the Velcro, and install in the new location.

Work as described but it takes driving few miles on the road to get the accurate tire pressure reading. Installation was easy and kit has all tools needed to secure all four tires sensors easily. The display is super bright clear and showing real time reading with temperature on each tire. It also shows the battery power at startup with beep. Display adapter plug into cigarets port and it has usb port on side for your needs. Overall work as it intended and no flaws. Will buy again for my other car.

Instead of fixing the 4 broken tire pressure monitors on my car tires for over $250, I bought this and plugged into my 12 volt input in the car and it constantly shows my tire pressure. Unit works awesome...you just plug the display screen in the 12v input and screw the air caps on each tire and it automatically sends the pressure to the unit inside the car and you can constantly see your tire pressure. The tire pressure is very accurate. Also very versatile as you can remove anytime and put on a trailer or another car. The only item I would note as a small negative is that the air pressure tire caps are slightly large compared to the normal caps that go on a tire valve. But it doesn't seem to have any negative effect and I am very happy with my purchase.

I do like that it's quick and easy to set up, has expandability however, just how others have mentioned, it is off by 1-2 psi. If it could be calibrated, that would be good, but if mine is saying my tire is at 29psi, it's actually at 30.5. Consistently. Otherwise, it works great, easy to read, small form factor. Love that it has USB ports on the side so that you could still charge if need be. Would I recommend it? Yes but with the caveat about the psi being off.

Really nice for people who don't have a sensor in their cars

ممتازة صارلها تقريبا سنة عندي مافيها مشكلة

منتج ممتاز للسيارات اللي مافيها حساس الكتروني مقارنة بشعره وفائدته. مشكلته ما يفصل من الولاعة أوتوماتيك إذا طفيت السيارة. يحتاج تشبكه كل مرة تشغل وتطفي. قياساته دقيقة وجيدة

ممتازه و سهله و دقيقه في القراءه

Fantastic device great tpms realy helpful during travelling
