Tire pressure monitoring systems
how accurate are they? worth the 300 price tag? Yes I do realize one answer reflects the other.

How exactly do the external screw on sensors measure accurate tire temperature? Seems spinning on a cap outside the tire in the ambient air couldn't provide an accurate tire temperature could it?
You are missing the whole point of having a TPMS. You measure accurate tire pressure with an external gauge prior to the tires heating up. The TPMS is just to alert you of a tire malfunction caused by low/high pressure or temperature. Knowing accurate tire pressure going down the road is redundant as it changes with speed, altitude, temperature, road conditions....ect.
