Exactly. More people are going to see their TPMS light turning on here shortly as soon as we get the first blast of cool Fall temps rolling in...which hasn't happened just yet in most parts of the US.
Since I can see my tire pressure feedback constantly from all 4 tires, I can tell you I've seen a 4-5 PSI change in my tires in 1 day during the last couple of weeks as the air temps vary from the 40s to the 90s in a single day.
