This utility allows vehicle owners to adjust the vehicle’s computer for changes in tire dimensions. By inputting the original and new tire sizes, the system calculates the necessary adjustments to parameters like the speedometer, odometer, and anti-lock braking system (ABS). For example, switching from a 205/55R16 tire to a 225/45R17 tire requires recalibration to ensure these systems function accurately with the altered rolling circumference.
Accurate vehicle computer settings are crucial for maintaining proper vehicle operation and safety. Incorrect calibration due to tire changes can lead to inaccurate speed readings, affecting safety systems and potentially leading to legal issues. Historically, such recalibrations required specialized equipment and professional expertise. This tool empowers vehicle owners to manage this process themselves, saving time and potentially reducing expenses. Proper calibration ensures the vehicle’s systems operate as intended, contributing to optimal performance and safety.
