The specified vehicle model typically utilizes a tire dimension of 215/45R17. This alphanumeric designation provides key information about the tire’s width, aspect ratio, construction type, and rim diameter. For instance, “215” indicates the tire’s width in millimeters, while “45” represents the aspect ratio, calculated as the sidewall height as a percentage of the tire’s width. “R” signifies radial construction, and “17” denotes the wheel’s diameter in inches.

Correct tire fitment is crucial for maintaining optimal vehicle performance, safety, and fuel efficiency. Using the manufacturer-recommended dimensions ensures accurate speedometer readings, proper handling characteristics, and adequate clearance within the wheel wells. Deviation from the specified size could negatively impact braking performance, ride comfort, and overall vehicle stability. Historically, the tire size evolved alongside advancements in vehicle design and engineering, with specific dimensions chosen to complement the car’s weight distribution, suspension system, and intended use.
