TymateTPMS Tire Pressure Monitoring System - Large Colorful Screen TPMS, 4 Alert Modes with 4 Advanced External TPMS Sensors, Real-time Detection Tire Pressure&Temperature (0-87 PSI)

Much clearer than the demo video in ad showed. Great color on screen. I adjusted my tires pressure and then matched this unit to match. Instructions are clear. Plug in reader first. Then install sensor on each valve stem. This is great way to keep pressure adjusted for temperature changes outdoors. This unit also shows temperature of each tire. Good to have in case a brake is dragging any wheel and overheating that tire. Also this shows the battery voltage. Good to have to monitor the battery and alternator. My battery is a few years old, so now I can watch and catch it before it fails. Tire seller wanted $400 to replace my original tire sensors. This is better as it shows the pressure all the time and for each tire. Added: Amazing accuracy. Pressure reading adjusts with the cold outside temp. Once driven a short distance it is rock steady. Added benefit have a voltage readout. I am so glad I bought this. Saves me all those tire checks in the cold.

This model was the 3rd "under $100" TPMS system that I purchased for my 30' travel trailer with tandem axle. (The 1st 2, Brand X models just didn't work well at all. Wish I had bought this system first.Likes: - works as described, I can monitor tire pressure and tire temperature as well.- BIG screen fonts, easy to read- adjustable brightness levels- sturdy base mount- sensor battery life seems to be good. (original batteries now in 2nd year of use)- accurate information- quick tap on the receiver and you can view the tire temps.- alarm system for pressure and temperatures- long power cable. I can plug into the cig 12v in the backseat of truck, run the cable between the seats and snake it up the dash to the display. Nice and neat, keeps down the "cable clutter" in the cab.Dislikes: - DC hookup only, need cig lighter plug-in.- can be quirky. Occasionally need to unscrew/rescrew a sensor to get it to connect to receiver(sometimes I'll get 3 sensors reading immediately and the 4th will connect and read maybe 5 minutes down the road)Overall this has been a good product. We traveled about 5k miles last year with this unit. I have the 15" Goodyear Endurance tires at 80lbs. Provides confidence to run down the highway with your tires showing about 83lbs after they warm up at highway speeds. My goal is to give myself some advance warning if a tire is about to go. Even still, I'll do a walkaround at stops to check things out.After a trip, I disconnect the sensors and put them in a little bag until the next journey. I also put the little black caps back on the Shrader valves to keep everything clean.Edit: Oct 2024. Still working great. I also use 2 sensors (Left Front/Right Front) on a boat trailer. I set the "psi alarm" to 60psi when running the trailer. Trailer tires max psi is 50psi so I run them at 45. BE SURE to unscrew them before launching - they do come with little covers (I don't use them) but I'm not sure if they are 100% waterproof. I've swapped out the CR1632 batteries a couple of time now. The set comes with a little clamshell tool to easily swap the batteries. Again, very pleased with this product!

I tested it in my truck for about a month in all kinds of weather. It worked great. However I ordered this for my car hauler trailer. I was afraid it would be too far for the signal to get to the monitor but it worked great, I have it on a 20’ trailer. It does feel very cheap and I don’t like that it doesn’t have a transmitter. But it works and that’s all that matters. For the price is great. Not sure if I would trust it on the rv going long distance but it’s better than nothing.

The product description sounds very promising for a usage that would not require tue sophistication that people might need for travel trailers and such. I read the reviews, the Q & A's, called customer service 3x's, read the manual MULTIPLE TIMES, emailed back and forth to customer service 4x's. I only need 2 sensors in my situation, not 4. There is nothing in the manual explaining how to operate the unit this way but they do mention using and extra sensor for a spare. I can not get the "not used" sensors to drop off, even after driving 49 minutes....per suggestion of customer service and Q & A's. It flashes red and reads zero pressure with and alarm. Customer services claims this has NEVER HAPPENED BEFORE. Apparently they do not read their own q&a b/c it is a topic. They even sent me.directions to delete the 2 sensors only to find out they sent me the wrong info...this unit does not delete sensors. Now they want me to send them videos to "prove" the problem. I ordered the unit and installed the 2 sensors for an upcoming trip. Verbal communication told me they would send me.a.new unit, I offered to send the old one back. I am not trying to scam them out of a unit, I just want a working unit. Obviously i will not have a unit for my trip. My suggestion, consider upgrading to a different unit. BTW....customer service is a.call center reading from a script. They REFUSED to let me talk to the tech department to see if we could problem solve together. Buy a different unit!
