TireMinder TMG400C Tire Pressure Monitoring System 4pk

The device is easy to program. I have had ghost alarms where the receiver thinks a transmitter is missing or tire has blown. Also when the RV and tow vehicle are brought together the receiver is suppose to "see" the RV's wheel transmitters in 20 to 30 minutes. This is not happening. I have towed for over 45 minutes and the transmitter continues to warn that the trailer wheel sensors are not there. Disconnecting and reconnecting a RV wheel transmitter to "wake up" the receiver did not work. There is, per Tireminder, a firmware update to eliminate alarms when the RV and tow vehicle are separated yet mine still gives RV alarms when separated. Other minor nuisances.Tireminder urges to install the booster. I have it but have yet to experience interference. It remains in the box. I have the rear dually tires and four trailer tires monitored. No need to monitor (towing) front wheels since you will quickly know if there is an issue. TireMinder customer service agrees. I have well over $400 invested in a system that kinda sorta works.Update: I installed the Booster the summer of 2013 summer in the trailer and have towed many miles since. The "ghost" alarms where the transmitter thinks a sensor is missing have ceased for the most part. I did have both right dually tires alarm within seconds of each other on a cold morning when the receiver awoke. The tires were properly inflated. Nothing since.Seems things have settled down and the system is doing its job. Again kudos to customer service. You call and they answer. Another bonus I had almost forgotten about is the battery exchange. You send them your old sensors batteries and they ship replacements. Free. I even got an email reminding me to check the sensors and batteries before towing this year.afinepoint

Programming the monitor is not all that simple. It takes a few tries to remember the sequence in which to press the buttons. Since I use it on my RV, which we take out every couple of months, I'll have to review the instructions before taking off on our next trip.Also, to check the tires while traveling, requires you to press one button repeatedly until it displays each tire conditions sequentially. Not a good thing while driving. I would prefer that the monitor displayed all the tire pressures without having to push any buttons. If I purchase another TPM system I'll look for this feature.

I purchased this monitor for my travel trailer as tire problems are constant worry when traveling the monitor was very easy to install and set up. the screen is very easy to read & the holder actually stayed on windshield & didnt fall off this is first trip i was'nt looking in mirrors watching for tire problems . Being able to read both temp & pressure very big plus only thing dont like is you cant shut monitor off when disconected from trailer , warning beeps get annoying after awhile

Installed new batteries and reprogrammed locations.200 miles into a 1500 mile trip resulted in failure of all tx on all four tires.reprogrammed and worked another roughly 200 miles and lost communication again .Receiver was all charged up as well. I had hoped to get better results.

This a great tire pressure monitoring device. I use it on my motor home and my toad (the veh I tow behind my RV) I know if I have a flat or if the tire gets to hot ( like if the toad's brakes are draging) before any damage is done. Love the unit, easy to program and easy to read.

To get the sensors to work I must unscrew each sensor and tighted them again every time I use my trailer. Would not buy again

had an issue with a bad sensor but TireMinder support was right there for me and quickly sent a replacement at no cost.

All three sensors read 4-5 psi lower than the tire was actually pressurized to.Tires were set to 60 psi and checked with a Milton stick, a Gorilla stick and they both showed, during multiple tests, that the tire pressure in the trailers tires were set to 60 psi; however, the tire minder sensors displayed either 55 or 56 depending on the sensor. I also checked the pressure on my Silverado tires and compared the two stick gauges against the internal tire pressure sensors installed by GM, and the stick sensors (Milton/Gorilla) were within 1 psi of the electronic sensors in the Silverado tires. (GM as well as other manufacturers use very accurate sensors due to their requirement to install these per Federal Law.)Ok, so I could live with adding about 5 psi to the reading as I drove. However, I also started to question the temps. They did not seem to rise as the pressure in each tire increased.Then, one morning, the system told me the right trailer tire battery was dead...sensor was less than three months old. So, no problem, changed the battery (they give you extra batteries); however, the control module would not recognize the sensor with a new battery. So I cleared all sensors and started from scratch and that sensor would NOT register. So, I had two extra sensor, I could not get any of the extra sensors to register with the system.The system was not useless and past the period of returning to Amazon.Basically, this system is not worth the price, in fact, it is not worth anything.Could it be returned under warranty for another system? Probably. But I don't want to have to reprogram the system every morning. Better to just check the tires with an IR gauge every stop for temps and check every AM for pressures, unless they appear to be lower during a stop.So beware...there are probably better units out there.
