Tire Pressure Monitoring System, TPMS for RV and Trailer, Solar Powered TPMS with LCD Display, 4 Sensors, Real-Time Pressure and Temperature Monitoring, Easy to Use (0~87 PSI)

This tire pressure monitor kit works great - the caps replace your tire stem caps and monitor the pressure and temperature. The pressure seems accurate, but the temperature seems like it might be more of an ambient temperature measurement since tire air temp would increase much more than this indicated in testing on a road trip. It updates every few minutes even while driving, and has alarms for above and below pressure and temperature. The monitor can charge with solar or USB, and the caps have small batteries that need replaced when they die. Very cool if your car doesn’t have built in monitoring.

If you set it for PSI the temps read in degrees C, if you set it for Bars then you get temp in degrees F. I don't know if it's just mine, or a glitch in how they were made, or something I've missed in the sparse and microscopic instructions. According to the docs, and common sense, bars are paired with C and PSI with F, as logic would dictate. If there's a way to set these parameters separately, I haven't discovered it. No big thing, as I'm concerned about pressure, not temp. but something to consider if you are.An installation tip:You may need some WD-40 or Corrosion-X for the valve stem, as the lock nut needs to run further down the threads than the old cap covers and there may be a bunch of road crud. Having a 13mm socket would be good, as it's hard to get much leverage with the little included wrench. Be sure to hold the stem with a pliers, if it's necessary to really crank to the nut initially, to avoid excessively twisting and damaging the stem.As far as accuracy, I tested it against another digital gauge I have and the pressures matched. No evidence of leaks, so I guess it's so far, so good.I'd have been happier if it had been delivered on time, but I guess that's a different review.

super easy to put on and set up, works perfectly, shows pressure and individual temperatures which can show a tire or suspension issue, low/high temp and pressure warnings, solar charge keeps up with use.

The media could not be loaded. I’m giving this TPMS kit 4.5 stars due to ease of use and functionality. I got this for my daughter, because her TMPS light stays on in the dash console. The dealer wanted $500+ to replace all internal TPMS monitors, programming, and reset the computer.This item is a safety feature. My daughter was going on the highway with 25psi in the front. I was extremely mad that she was not monitoring her tire pressure better.I did charge it beforehand, but there is no light, so I have no idea if it’s charged or not. I told her to leave the controller in the sun when it’s parked. She told me it automatically goes to sleep. At this time, I’m not positive if it auto turns on, but the manual says it does.I instructed her to monitor the controller at least one a day. There is a beeping noise if the pressure gets low, so that’s a plus.When you air up the tires, you either need to screw the locking nut all the way in or remove it. You need to leave wrench in the glove box, so that you can easily remove the sensors.If your TPMS sensors do not work or your car doesn’t have any notifications, I highly recommend doing something about it. This unit is a huge value play compared to the dealer. I know we all want our cars to be like new, but money is limited for most.

I like that solar powers the display unit, and the sensors all seem to be working well. My only worry is that the schrader valve washer included to help seal the system may degrade over time and start to leak. If and when that occurs I will update my review, but for now, it's working fantastically...definitely recommend.

Works as it should. Pretty easy to setup.

Picked these up because we have a couple older cars, one from the '70s and one from the '90sthis is really for peace of mindit has an alarm if there is an air leak, like if you drive over a nail, which is nice.the only thing I wonder about is ... how long the batteries in the sensors (caps) lastI don't drive my older cars very often and I wonder how long the sensors will stay "good".but we'll see how it goes.There is a programming instruction guide, which is reasonably easy to understand, so you can set theOne final note: You screw these on to the valve caps onto your tire stem and tighten them down to eliminate air leaks.but if you need to add air to your tires, you have to repeat the process every time.its fine if your tires are in good condition, but if you have a slow leak, you would not want to be using these.

As a fleet manager for a logistics company, I've been looking for tools to improve our fleet's safety and efficiency. This tire pressure monitoring system perfectly meets our needs. It’s easy to install and can monitor each vehicle's tire pressure in real-time, providing timely alerts to prevent accidents. We’ve noticed a significant reduction in tire-related issues and downtime since installing this system. Our drivers also report feeling much safer on the road. For any logistics company, this is an indispensable device that greatly enhances operational efficiency and safety.
