Physically looking at the tires isn't going to detect if the tires are off 3-4psi. Air will expand and contract, dependant on the ambiant temp. Even Nitrogen will expanda and contract slightly.
Your TPMS will go off when the temp drops or increase dramatically, because your air pressure is off from its norm by a certain percentage. You should check your tire pressure at least once a month, no matter if you have nitro or air. You should keep the pressure close to what's recommended in your driver side door jam, no matter what time of the year it is.
