The specified dimensions for the tires on a particular model year of a compact vehicle are essential information. These measurements, typically expressed in a standardized format, dictate the physical characteristics of the tire, including its width, aspect ratio, and wheel diameter. For example, a common set of numbers and letters might be 205/55R16, indicating a tire width of 205 millimeters, a sidewall height that is 55% of the width, and a radial construction designed for a 16-inch wheel.
Adhering to the recommended specification is critical for maintaining vehicle performance, safety, and fuel efficiency. Deviating from the original equipment manufacturer’s (OEM) recommendation can negatively impact handling, braking, speedometer accuracy, and the overall driving experience. Historically, these specifications have been carefully engineered to optimize the vehicle’s ride quality and stability. Choosing the correct dimensions ensures proper fitment within the wheel wells and prevents potential rubbing or interference issues.
