I have two crossfires and have encountered the same problem in both. It seams when it rains very hard leaving standing water, if the water covers the tite valve, ( and thats easy in low profiles) it may short out the sensor and send a false signal to the instrament panel. If this does occur, you need to take to dealer to have computor reset. MAKE SURE THOUGH THAT YOU HAVE THE TIRES INSPECTED JUST IN CASE IT WASN"T A FALSE ALARM.
