Official abstract text for this publication.
A tire data information system includes at least one tire that supports a vehicle and a processor. At least one sensor is mounted on the tire and is in electronic communication with the processor. The sensor measures a temperature and a pressure of the tire. A memory for storing tire identification information is in electronic communication with the processor. A tire wear state estimator generates a wear state of the tire and is in electronic communication with the processor. A tire wear rate estimator generates a wear rate of the tire and is in electronic communication with the processor. An antenna transmits the temperature, pressure, identification information, wear state, and wear rate of the tire to a display device that is accessible to a user of the vehicle. The display device includes indicators for showing the temperature, pressure, identification information, wear state, and wear rate to the user.

What is claimed is: 1. A tire data information system comprising: at least one tire supporting a vehicle; a processor, at least one sensor mounted on the tire and in electronic communication with the processor, the at least one sensor measuring a temperature and a pressure of the at least one tire; a memory for storing tire identification information, the memory being in electronic communication with the processor; tire wear state means for generating at least one of a measurement and an estimate of a wear state of the at least one tire, the tire wear state means being in electronic communication with the processor; tire wear rate estimation means for generating an estimate of a wear rate of the least one tire, the tire wear rate estimation means being in electronic communication with the processor; transmission means for transmitting the temperature, the pressure, the identification information, the at least one of a measurement and an estimate of a wear state, and the wear rate estimation of the at least one tire to a display device accessible to a user of the vehicle; and the display device including a temperature indicator, a pressure indicator, an identification information indicator, at least one of a wear state measurement indicator and a wear state estimate indicator, and a wear rate estimate indicator. 2. The tire data information system of claim 1 , wherein the tire wear state means includes a wear sensor mounted on the tire that generates a measurement of wear of the at least one tire. 3. The tire data information system of claim 1 , wherein the tire wear state means includes a wear estimator that generates an indirect estimation of the wear state of the at least one tire. 4. The tire data information system of claim 1 , wherein the processor is in electronic communication with a CAN bus system of the vehicle. 5. The tire data information system of claim 1 , wherein the memory is integrated into the at least one sensor. 6. The tire data information system of claim 1 , wherein the at least one sensor includes at least one of a tire pressuring monitoring system sensor, a tire ID tag and a tread wear sensor. 7. The tire data information system of claim 1 , further comprising at least one sensor being mounted on at least one of the vehicle and a wheel on which the tire is mounted, the at least one vehicle or wheel mounted sensor being in electronic communication with the processor. 8. The tire data information system of claim 1 , wherein the transmission means includes wireless transmission from the processor to a remote server and wireless transmission from the remote server to the display device. 9. The tire data information system of claim 8 , wherein the display device includes a display screen showing notifications to the user that are downloaded to the display device from the remote server. 10. The tire data information system of claim 1 , wherein the transmission means includes wireless transmission from the processor to the display device. 11. The tire data information system of claim 1 , wherein the display device includes a display screen showing an image of the vehicle and the pressure indicator for the at least one tire at a position on the vehicle image that corresponds to a position of the at least one tire on the vehicle. 12. The tire data information system of claim 11 , wherein the display device includes a display screen showing a status indicator adjacent the pressure indicator when the at least one tire is being inflated. 13. The tire data information system of claim 1 , wherein the display device includes a display screen showing an image of the vehicle and the indicator of at least one of a measurement and an estimate of wear state for the at least one tire at a position on the vehicle image that corresponds to a position of the at least one tire on the vehicle. 14. The tire data information system of claim 1 , wherein the display device includes a display screen showing an image of the vehicle and the wear rate estimation indicator for the at least one tire at a position on the vehicle image that corresponds to a position of the at least one tire on the vehicle. 15. The tire data information system of claim 14 , further comprising a remote server in electronic communication with the processor, wherein at least one of the wear rate estimation and the wear state measurement or estimate is transmitted to the remote server for comparison to tires on other vehicles, and selected information from the comparison is transmitted from the remote server to the display device. 16. The tire data information system of claim 1 , wherein the display device includes a display screen showing an image of the vehicle and the temperature indicator for the at least one tire at a position on the vehicle image that corresponds to a position of the at least one tire on the vehicle. 17. The tire data information system of claim 1 , wherein the display device includes a display screen showing selected tire identification information for the at least one tire. 18. The tire data information system of claim 1 , wherein the display device includes a display screen showing a tire load estimation for the at least one tire. 19. The tire data information system of claim 1 , wherein the processor is disposed on the vehicle. 20. The tire data information system of claim 1 , wherein the processor is integrated with the at least one sensor.
