Tire rotation warning
A vehicle includes a tire rotation reminder system. The system includes a controller that generates a tire rotation reminder based on a predicted driving time for attaining a predetermined difference in tread wear between front tires and rear tires. The predicted driving time is based on a rate of change of a difference between a front tire circumference and a rear tire circumference. The tire rotation reminder is output when the predicted driving time is less than a predetermined time. The tire rotation reminder system may interface with at display to output additional information related to tire rotation. The tire rotation reminder may be communicated using a visual indicator, an audible indicator, and a tactile indicator.
1. A vehicle comprising:
a controller programmed to output a tire rotation reminder in response to a predicted driving time for attaining a predetermined difference in tread wear between front tires and rear tires being less than a predetermined time, wherein the predicted driving time is based on a rate of change of a difference between a front tire circumference and a rear tire circumference.
2. The vehicle of claim 1 further comprising a display module configured to display the tire rotation reminder and the predicted driving time, and wherein the controller is further programmed to output the predicted driving time for display.
3. The vehicle of claim 1 wherein the controller is further programmed to receive an operator input and, in response to the operator input, output instructions for tire rotation.
4. The vehicle of claim 1 wherein the controller is further programmed to receive an operator input and, in response to the operator input, inhibit outputting the tire rotation reminder for a predetermined inhibit time.
5. The vehicle of claim 1 wherein the controller is further programmed to output the tire rotation reminder in response to a speed of the vehicle being less than a predetermined speed.
6. The vehicle of claim 1 wherein the front tire circumference is an average circumference of the front tires.
7. The vehicle of claim 1 wherein the rear tire circumference is an average circumference of the rear tires.
8. The vehicle of claim 1 further comprising one or more of a visual indicator, an audible indicator and a tactile feedback generator configured to indicate the tire rotation reminder to an operator.
9. A tire rotation reminder system comprising:
a tire rotation indicator; and
a controller programmed to activate the indicator in response to a predicted driving time for attaining a predetermined difference in tread wear between front tires and rear tires being less than a predetermined time, wherein the predicted driving time is based on a rate of change of a difference between a front tire circumference and a rear tire circumference.
10. The tire rotation reminder system of claim 9 further comprising a display, wherein the controller is further programmed to output the predicted driving time to the display.
11. The tire rotation reminder system of claim 9 wherein the tire rotation indicator is a visual indicator.
12. The tire rotation reminder system of claim 9 wherein the tire rotation indicator is an audible indicator.
13. The tire rotation reminder system of claim 9 wherein the tire rotation indicator is a tactile indicator.
14. The tire rotation reminder system of claim 9 wherein the controller is further programmed to receive a user input, and in response to the user input, deactivate the indicator for a predetermined deactivation time.
15. A method for detecting a tire service interval for a vehicle comprising:
displaying a tire rotation reminder in response to a predicted driving time for attaining a predetermined difference in tread wear between front tires and rear tires being less than a predetermined time, wherein the predicted driving time is based on a rate of change of a difference between a front tire circumference and a rear tire circumference.
16. The method of claim 15 further comprising displaying the predicted driving time.
17. The method of claim 15 further comprising inputting a user input and inhibiting, in response to the user input, display of the tire rotation reminder for a predetermined inhibit time.
18. The method of claim 15 further comprising displaying, in response to displaying the tire rotation reminder, instructions for tire rotation.
19. The method of claim 15 further comprising displaying, in response to displaying the tire rotation reminder, contact information for a nearest service facility.
20. The method of claim 15 wherein displaying the tire rotation reminder is further in response to a speed of a vehicle being less than a predetermined speed.
