EOHMAK Tire Pressure Monitoring System Wireless Solar TPMS, Tire Pressure Monitor with 4 Sensors Real-time Display Temperature Pressure for Car RV SUV MPV Sedan (Internal)

I’d you have access to a tire machine, or are having tires put on these go INSIDE the tire and are the valve stem. Updates pressures regularly and so far after almost a year, no problems. Shows pressure and temperature of all 4 and sits on your dash or window and unit runs on solar.

it works very well. the pressure readings are within 1 psi compares to my manual psi measurements. the unit triggers on one of he tire, LF, due to pressure drop from 33 psi downs to 28 psi. it turns out there is a leak on the tire bead and rim. removed and reseated the LF tire.

Love the display and internal mounting so that there is not a nub on the tire, however it did not fit on my AMG Monoblock rim, so I could not use.

Very cheap quality the monitor starts to flicker after only a week of use! Stay away from it! As it's an internal sensor system returning it cost more than ignoring it!

Excellent product, get the job done. Has saved my tires multiple times.

I installed this system in a 2003 Toyota which doesn't have OEM TPMS to replace a cap-type aftermarket TPMS which I thought stood out too much on the wheels. I have the tools to break the bead on a car tire so it was easy enough to install these in place of the original rubber stems. I like how the screen mounts permanently on the windshield and is charged off of solar. I installed everything and the sensors all read out in the correct location. I'm not sure they are accurate based on 2 air pumps I used that have their own gauges but I'll try it with a new stick gauge to be sure- they seem to read low by 4-5 psi. I would be curious to know where to get replacement sensors when the batteries in these sensors die.

My 2005 work car has intermittent loss of air from one or more of the tires. I was constantly checking the pressures. I had previously purchased a TPMS system for a trailer, and while it worked great, it was definitely a pain to remove the sensor so you could add or reduce air pressure. I purchased this internal TPMS system and broke the tires down myself at home. Reseated the tire and filled with air. Pretty easy. My only complaint with this monitor is the solar cell is on a pivot that wont pivot enough to give me a good view of the display. The solar cell is meant to be 2 sided taped to the windshield so it gets plenty on sunlight to recharge. My fix for this is Scotch tape. Ugly, but functional.
