The specified vehicular model from Toyota, manufactured in 2009, requires tires of a particular dimension for optimal performance and safety. This dimension, often expressed in a format like P215/65R16, indicates the tire’s width, aspect ratio, and rim diameter. For instance, a tire marked P225/60R17 would denote a passenger tire with a section width of 225 millimeters, an aspect ratio of 60 (meaning the sidewall height is 60% of the section width), and a rim diameter of 17 inches.
Selecting the correct tire specification is crucial for maintaining the vehicle’s handling characteristics, braking efficiency, and fuel economy. Deviations from the manufacturer’s recommended size can negatively impact speedometer accuracy, ride comfort, and even stress components of the suspension system. Original Equipment (OE) specifications are often determined through extensive testing by the vehicle manufacturer to ensure a balance of performance, safety, and longevity.
