A TPMS is a great idea.
On the subject of pressures, when Tom installed his TPMS, there was a significant difference in the readings of the TPMS and his tire gauge. We checked it with my tire gauge which had been calibrated prior to my buying it a number of years earlier and it was about 1/2 way between the readings of the TPMS and Tom's tire gauge. The TPMS manufacturer claims his units are within, as I recall a pound and a half. My gauge read 3 pounds less than the TPMS and Tom's gauge read 7 pounds less. So the moral of the story is try to get them consistent, don't worry if you are a pound or two over because your gauge likely isn't that accurate anyway.
