The specified vehicle model utilizes a particular set of measurements that define the dimensions of the tires installed on the vehicle. This measurement encompasses the tire’s width, aspect ratio, and the diameter of the wheel it is designed to fit. For example, a tire might be designated as 225/40R18, indicating a width of 225 millimeters, an aspect ratio of 40%, and a wheel diameter of 18 inches.
Correctly adhering to the factory-recommended measurements is crucial for maintaining optimal vehicle performance. Deviation from these specifications can impact fuel efficiency, handling characteristics, speedometer accuracy, and overall safety. Furthermore, adhering to the recommended specifications ensures compatibility with the vehicle’s safety systems, such as anti-lock brakes (ABS) and electronic stability control (ESC). The understanding of these dimensions contributes significantly to informed decision-making regarding replacements.
