I like to use an old fashioned air pressure guage for my tires.
The TPMS system is kind of annoying for an old-timer like me. I like to check the air pressure in the morning before driving, and I also like to add enough air for good handling. The correct Tire pressure helps the tires wear evenly, and since tires are like "balloons" in the sense that they can only lose air over time, it is better to have slightly higher pressure then factory recommended specs, in them to begin with.
On the other hand, there is no need to over-inflate the tires which can reduce the tires contact patch with the road.
A few years back, many years back now, Ford tried to blame the roll-over accidents of the Expedition on the tires instead of the bad suspension design.
