Methodology and apparatus are disclosed for transmitting data to a tire electronics device contained in a tire. The tire electronics device includes a vibration sensor and microcontroller configured so that vibrations sensed by the vibration sensor may be analyzed to determine if the vibrations occurred according to a predetermined sequence. Detection of the predetermined sequence of vibrations may be used to trigger data transmission from the tire electronics device or may be used as an indication to the tire electronics device that it should store additional data or modify its operation in a predetermined fashion. Data may be transmitted to the tire electronics using a variety of mechanical and electromechanical devices including permanently or temporarily installed traffic lane devices or portable mechanical or electromechanical devices.
