The original equipment dimensions for the tires of the model year 2011 of a specific hybrid vehicle manufactured by Toyota are a critical specification. This measurement is typically expressed as a combination of numbers and letters denoting the tire width, aspect ratio, and wheel diameter, providing precise details about the suitable tire for the vehicle. For example, a common tire specification might be 195/65R15, where 195 represents the width in millimeters, 65 indicates the aspect ratio (the height of the sidewall as a percentage of the width), and 15 signifies the wheel diameter in inches.
Adhering to the recommended tire specification ensures optimal vehicle performance, safety, and fuel efficiency. Deviation from these specified measurements can negatively impact handling, braking distance, and speedometer accuracy. Historically, manufacturers have determined these dimensions through extensive testing and engineering to match the vehicle’s suspension, weight distribution, and intended use. The correct specification contributes to a comfortable ride, reduced tire wear, and compliance with safety regulations.
