My wife was driving home from work last week and informed me that her indicator light for the tires had come on. I checked her pressures and they had fallen to 29psi on two of the tires and 30 .5 on the other two.
I filled to the proper psi on all four and the light has not come back on.

Considering the cost of having to replace the tires due to lack of proper inflation, I don't mind if they are oversensitive. I would rather not let them run underinflated.
