We have an EEZ tpms on our Axis. Like others, above, I've noticed that tire pressures vary slightly from the manual tire gauge I use when I measure them. As previously, stated, no big deal. I have noticed, however, that our inside right rear tire gets and stays around 10-12 degrees hotter than the other tires when we're traveling. So far, it hasn't gotten hot enough to set off the monitor alarm but I have no idea why that one tire is running hotter.
