mine just came on this morning. 3/4 (didn't take the time to check the last one, in a rush) tires were down to ~30psi. it's been mid 50s at night and mid 70s during the day until yesterday. first time it's stayed cold (40-50ish) for over 24 hours.
i assumed that it was just the air temp, plus i haven't checked my tire pressure but once since i got the car 3 months ago. glad to see it works lol
