The specified vehicle model and year necessitates a particular measurement for optimal tire performance. This measurement encompasses width, aspect ratio, and rim diameter, and it ensures proper fitment within the wheel wells while maintaining accurate speedometer readings and safe handling characteristics. For example, a common specification includes a combination of numbers and letters, such as 175/65R14, indicating the tire’s width in millimeters, the sidewall height as a percentage of the width, and the rim diameter in inches.
Correct tire dimensions are crucial for maintaining vehicle safety and efficiency. Adherence to the recommended specification ensures proper load-bearing capacity, contributes to predictable handling, and optimizes fuel economy. Historically, selecting the right tire dimensions was a more complex process relying heavily on manual measurements and generalized recommendations. Modern resources and vehicle documentation provide precise information, simplifying the selection process and reducing the risk of incompatibility.
