TireMinderi10 RV TPMS with 6 Flow Through Transmitters, Black

My personal experience.Mercedes Sprinter RV's do not come with TPMS.Just returned from a 100 mile trip using the TireMinder TPMS unit worked flawless what peace of mind to see in real time tire status.During our recent trip we noticed three trailer rigs with tire blow outs along the way, had they had this unit or similar they would have seen what was immanent and likely avoided the time & cost dealing with a tire blow out seeing before hand tire pressure drop and rising temperatures which is the main cause of tire blow outs.Here are some tips (my opinion) if installing on Sprinter based RV's.TipsYou can easily install the TPMS head unit onto lower left corner of windshield (suction cup) to avoid obstructing view. Very easyUse the cigarette adapter to plug into top dash 12 volt receptacle under dashboard cover (Sprinter) where accessories; phone power plug in etc.) run the 12 volt wire out from the top dash accessory space, press wire to and inbetween crevices and adjacent surfaces to conceal, route wire through cup holders 'area' over to lower left of window and plug into the TPMS unit.FYI, Power only comes on when ignition is on, unit will also charge.Antenna boosterThere is an antenna booster unit to keep signal strong given the distance between cab and trailer wheels it comes with 12 volt ale-gator clips, connected clipped direct onto 12 volt RV battery terminals (under steps) placed antenna booster unit in the battery bay. This is fast , easy to do and should work similar on most RV's? If you have a trailer, multiple wheels it is recommended to locate secondary antenna unit closer to trailer wheels and mount under trailer.A tight fit (sensors)My RV rear dual tires has slotted rims with metal valve stem extensions if you don't have have metal valve extensions including a 'solid bracket' for the longer inner tire valve extension its likely damage to the valve stem sensors and rims will occur as the sensor cap will most likely bang against the rim due to extreme centrifugal force exerted.Installation of valve sensors.If you have slotted rims you may find that the TireMinder valve sensors can not clear the rim slot when first screwing valve sensor in just remove, unscrew the sensor cap and continue to screw the sensors in and then screw the sensor caps on.Programing the sensors is straight forward might take a few minutes to get the hang of it but the instructions are clear.ProsUnit looks smart, professional, solid build a great valueTPMS unit is very easy to read against sunlight, cycles quickly between front and rear tiresPSI measurements are very accurateNo connectivity issues, consistent signalTPMS unit window mount suction cup provides solid mountHard wiring is not required 'plug and play'Extra sensor batteries are providedConsThe valve sensors are larger than expected, somewhat of a challenge to screw in on a few depending on actual placement of valve stem extensions alignment with Aluminum wheel slots (to place the sensor in between) right down to the millimeter!The sensor size is dictated by the sensor disc batteries combined with electronics packed in each its quite amazing. I don't know how they could make the sensors any smaller.Suggestions to MFGConsider providing diagrams and tips noted above in the instructions.A TPMS system is one of the most important investments you can make, the difference in a hoping everything is good versus knowing is paramount regards to safety.I have no contact with seller or manufacture just want to help anyone who may have questions. Happy trails!

Finished setting up the tireminderi10. I have six flow=through transmitters - 4 on my 4 cylinder tacoma and 2 on my single axle Aliner. The actual pressure in the tires was 32 in the front and 35 in the back. The TM shows between 29-33 for those - meaning one reads 1 psi high and the other 3 read 3 to 5 psi low. I don't believe there is a way to calibrate, so I noted the variance on a little notepad. The trailer tire sensors on the single axle are more 5 and 6 psi low.I noticed that the trailer tires sometimes showing n5 which I found out means No Signal. It took them a good 24+ hours to correct and now they read good pressure. When the monitor is too far away from them, those two sensors show n5. I didn't see an error code or message table in the manual to decipher what things mean. Maybe that is the only message possibiity.I love being able to see exactly what the psi and temp of all my tires are at all times, so I much prefer the monitor instead of the app. The different models of Tireminders and I wonder if they use the same manual for them because some of the instructions don't make total sense. I also wish that I could join a TireMinders Owners Group and ask questions of other users. Rv'ers have some great advice and answers and you can talk to people at all hours.TM has responded to a message I sent via facebook. Even though the system isn't perfect. I love having it. It makes me feel better.I would buy this again.

2nd I’ve owned. Peace of mind being able to track pressures and temperatures of all six tires on my rv.

I got these to replace and system that did not have enough range to work on my fifth wheelI was installed them when I received them they where a little hard to get paired I ended up buying new batteries and replaced all of them it then pair as it should after installing them I put my tow vehicle in shop I got it back a few days after my thirty day period and I was preparing for a long trip checking everything and the tpms was not working. I will be replacing with a different brand and source as well.

These did not fit through the holes in my rims, the sensor is offset on the flow through making them asymmetrical.To make them work I would have to install extensionsExtensions render the security feature useless as you can simply unscrew the extension with the sensor

See what your tires are doing down the road, check presses and temp of all tires

The charging port has always been difficult to attach the charging cord. Now the inside of the port has broken I hope they will offer a replacement.UPDATE: Tireminder has responded and are sending me a new unit. I’m very impressed with how quickly they responded.

Item arrived with all components as described. Installation was not difficult being done by one person. I initially only installed the tire pressure sensors only and not the range extender because I was only putting it on a 2 axle truck. It states the system will read +/- 1 psi. The front tires are 105psi and the reading was showing 100/102 psi on the screen. The rear tires are 120psi and the reading was showing 113/111/112/112 on the screen. 2 weeks later, I installed the range extender and the reading was showing 98/99 psi on the front and 115/111/111/111 on the rear. Both times, the readings were taken first thing in the morning and tires were aired to proper psi and checked with a manual gauge.After a month of using the system, the readings are still reading consistent within this range. So, I simply adjusted the system to show the psi readings to be the set psi for each of the tires. Other than the readings being off, I have really enjoyed the piece of mind of being able to keep track of the tires pressures, as I frequently get nails in the tires due to my business.

Device works perfect and gave me great piece of mind to be able to monitor my tire pressures and temp, easy installation as well!
