As I follow this thread and read intently every post, I have to comment that I am somewhat puzzled and perhaps even dismayed about the posts regarding up to an hour delay on the signal loss notification.
As one who has experienced 3 catastrophic tire failures and not knowing any of them until much damage was done, I have to wonder why this is perhaps considered "normal".
Does this not rather defeat the purpose of the TPMS?
A lot can happen in an hour. Pick up a piece of road shrapnel and a tire is gone in minutes, not hours.
Makes me wonder why they would be this way. It seems like this should be classified as a bug in the system as opposed to designed that way.......
