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)

Quality product at a fair price, Easy to install, operate, very reliable, and can review actual real tire pressures on all tires including tire temperature showing possible tires out of alignment scuffing causing abnormal heating of a heating tire.

Solid and straightforward tyre pressure monitoring system. Very easy to install, and every sensor showed exactly the same reading that was first checked with a professional grade air pressure gauge (Wonder Eurodainu). Has been working without any problems in continuous sub-zero temperatures (-10...-15 C) for now. Yet long term performance is too early to tell, but so far is looking good. Easy-to-understand manual and installation process. Batteries are included in the sensors. Just connect the gauge and the sensors, and they calibrate automatically. Gauge wakes up and closes down based on the 12 V current, so if your cigarette lighter works when the key is on, then it's practically fully automatic operation. Minimal use of current, so can easily be used together with a cigarette ligher hub. Good purchase!

I defeated the OEM Tpms in my Rav4 when I upgraded my tire tize. I used this for a more informative monitoring of my tire pressure. I also have another one just like this on my tow behind RV. Works beautifully and the fact that it starts with system voltage upon start up and displays temperature is a great add on. No complaints with either of my units. Great product to have.

For the price, it works pretty good. It does not always seem to update from the left rear like the other wheels do. It at least would let me know if one tire is deflating and when first installed, the tire pressures were dead on. The tire temperatures as not so accurate, but again I think it would let you know if a tire was running hot. In the units defense, this is benig used in Minnesota installed in December and some extreme cold temperatures.

Accurate and easy to install. When checking between the digital readout and other tire pressure monitors the difference is at most +/-1 psi. Only partial knocks are the locking install method (doesn’t really lock the modules onto the stem) and that when it gets very cold out the modules sometimes go out. But other than that a worthwhile upgrade for piece of mind.

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.

This has worked surprisingly well and is fairly accurate +/- 1 psi from a mechanical gauge. I use it in my older class B motorhome to monitor tire pressure on the road. The valve caps have locking nuts to secure the sensors in the valve which makes it a little more of a chore when adding air but I may just be lazy.

Works surprisingly well for the price. Works even in cold temps. You have to follow the instructions and use it the way it is intended to be used. May not have all the functions of other models, but it does show the pressure, and that is what matters.

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

Fantastic device great tpms realy helpful during travelling
