Tymate 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 (0-87 PSI)

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.

I originally bought a set of these for my father, who has some vision issues (not bad enough to not drive). He finds this system easier to use than a small pressure gauge for routine monitoring. The display is large enough to be easy for him to read.I was impressed enough to buy a set for my car, too. I haven’t had any issues with Bluetooth connectivity or, more important, any leaks caused by the monitor caps. I can’t speak to their longevity yet, but I’ve had mine for six months without issue.You won’t get an exact PSI number, of course—there’s about a plus/minus 2 PSI range, which the company is transparent about—but these will give you a better idea about the current state of your tires than passive TPMS systems or active systems that don’t display the PSI numbers.These are not a replacement for those in-built systems, or for checking your tires with a gauge periodically, but they do give some additional data and peace of mind.Edit: I also like that the monitor displays the 12v battery’s voltage when you start the car. That might help avoid a surprise dead battery.

Why did you pick this product vs others?:Looked to be the best value.One item to note, I used this on my 32' travel trailer on a 2000 mile roundtrip, do NOT use on wheels with rubber valve stems. Due to the weight of the sensors and the heat I had three of my valve stems fail within the first 300 miles of travel. I had to have all my valve stems replaced with metal stems during our trip and had no problems with them for the remainder of the trip. They do work great, I cross checked the psi readings with my other gauges.

Great product.bought for my tandem axle trailer. Works very well and I love that the temperature is on the screen as well. I subtracted 1 star due it sometimes forgets a sensor but eventually picks it back up.

seems to work well in an older Toyota Highlander. Had it for a week and adjusted the four tires to similar tire pressure. so far so good, the readings are about the same all the time. It does go up when driving and not all tires increased the displayed PSI the same, but close enough to track if there is leak in any of the tires.

After one day and one 500 mile trip, my initial experience is extremely positive! Both the sensors and the display can easily be moved between vehicles, which is a huge plus for me.I’ve seen some comments about the display being too large. I don’t understand that. Fitting four pressure and four temperature values in a smaller screen (and making them easily readable) would be very difficult.The product comes with an undocumented feature, which pleasantly surprised me. There are four copper(?) lock rings included, which can be threaded on to the stem first. Then once the sensor is in place, use the enclosed oddly shaped wrench to tighten the ring back onto the sensor. I’m sure it’s possible to remove the sensor with the lock ring in place, but it will most likely be much more difficult.Given the price, this unit appears to be a very good value!

Had I gotten these sooner they would have saved me money. If your TPMS is down for whatever reason (dead sensors in my case) this solution is less than the cost of one single OEM sensor. Easy to install and gives more information than the built-in system. I like the lock nuts to keep your sensor from flying off.
