Though I'm not a mathematician/physics guy, I'm guessing tire pressure decreases with speed of the vehicle and, thus, fools the system. Unless the software accounts for it, it's probably a typical event and nothing to worry about!!

Actually the opposite happens. The standard air pressure for our cars is about 35 pounds per square inch. Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 1-3 psi, depending on the tire.
