TM7 RV Tire Pressure Monitoring System, TPMS Set of 4 Sensors

This is a brilliant little device. I've owned higher end TPMS systems which we used on our RVs. We bought this one for our Honda CRV which only has the dash icon for a tire pressure issue with no details. This monitors pressure and temperature and could not be easier to install. Took only a few minutes. No set up. No calibration. It just turns on and works. It showed me my tires were over-inflated after a visit to a repair shop. In a few minutes got everything to factory specs before a long trip tomorrow. Looks good. Bright, easy to see. Compact size. The sensors are labeled so you can tell which goes on which wheel. And at 10% of the cost of the higher end units. Really nice TPMS.

Great product. I thought I had an out of the box failure on the left side transmitters but after driving a few miles they came on. Product works as it should and easy to use. Plug and play. I only use the trailer a few times a year so it's good to see the pressure on start up with no hassle. Highly recommend this brand.

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.

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. Yet to see how durable they are but recommended so far. The pressure readings seem accurate but the temperature reading function is poor.

So far I’m very pleased how well these work. 1st trip out I was thankful I had just bought them. On the way to camping I had a valve stem leave the chat and I was immediately alerted to loosing psi. On the way home another valve stem started to leak and again got the alert. Saved me a lot of $$ preventing new tires from going flat and tearing up my trailer.

I purchased this system last February for my camper. Since it's single axle, being aware of the tire status is very important, so this looked like a good option to monitor tire pressure and temperature. I installed and configured the sensors and everything looked good. Accurate pressure, etc. I put two of the sensors on the back tires of my truck and the other two on my camper. Distance between the camper sensors and the receiver in the truck is a little over 20 ft. These are supposed to be fine for 36 feet. Then we hit the road to the campground. About an hour into the drive, the right side trailer sensor just went away....nothing....nada. Then about half and hour later, the other trailer sensor went away. When we left the campground for home, the trailer sensors were working again, but again failed in about the same amount of time. I contacted Tymate support and they asked me to document the failure, so I sent them a video from our next camping trip where the sensors failed in the same way, which is included in this review. After a few email exchanges and suggestions like replacing batteries, moving the receiver closer to the sensors, and resetting the sensor connection, they suggested I might need a repeater. The repeater cost more than I paid for the Tymate system. I suggested they send me one to see if that resolved the problem, but they declined. Then, after putting the camper away in the shed, while putting the truck away, I noticed the the trailer sensors were now displaying tire pressure and temperature for the camper tires....and the camper was on the other side of the property. This product is unreliable, gives false readings, and sometimes no readings at all. Look elsewhere for a TPM. Don't trust this one. Update: 6/7/2026 Tymate Support and sent me the booster transmitter to see if it solved the sensor problem. I installed it as directed on the axle between the back wheels of the camper. On our recent trip, the trailer sensors did not go away as before. Obviously, the range of the sensors is significantly exaggerated. If It will not work on my small 16 ft. camper, it should not be sold without the booster. There are other misrepresentations in the item description. It does NOT have a "Sensor Disconnected System". It never indicates loss of sensor data...it just shows you the last data it got. The tire could fall off and you wouldn't know it. The item information also states that the tire pressure is 0-144 psi. Support informed me that max was 87 psi. It is NOT a "Real-time Tire Pressure Monitor System". I have removed it from my vehicle and camper. It does NOT work as marketed.

I bought this for a 2002 Toyota Camary works well, reads the tire pressure and the temperature of the tires, plugs right into a standard cigarette lighter, has a loud beep if you are losing tire pressure, I like this as a safety feature.

Easy to use and install. Full time monitoring of air pressure and accurate. With the crazy cost of gas keeping your tires inflated will pay you back big time in gas savings and tire ware.

ممتازه و سهله و دقيقه في القراءه

Excellent. Easy to install.
