Trailer Tire Pressure Monitors

I have the EEZ tire pressure monitor. Don't install it without also installing the repeater. If the monitor loses communication with any tire sensor it doesn't tell you for one (1) hour. If you are unlucky to have a problem during that time, too bad, it is too late. If you monitor pressure and temperature readings going down the road you will find that they vary on all wheels. The side where the sun is shining on will have a higher temperature and pressure. If you find one that does not vary it has lost communication with the monitor, it just reports the same readings for an hour. Before I installed the repeater there were two times where I had a flat and the monitor said every thing is OK. One was a blow out and the other was a nail in the tire.
