The specific dimensions of the rubber compounds affixed to a Toyota RAV4 are critical for vehicle performance and safety. These dimensions, typically expressed as a series of numbers and letters (e.g., 225/65R17), denote the tire’s width, aspect ratio, construction type, and rim diameter. As an example, a specification of 225/65R17 indicates a tire width of 225 millimeters, a sidewall height that is 65% of the width, radial construction, and a rim diameter of 17 inches.
Correctly specified dimensions ensure optimal handling, braking efficiency, fuel economy, and ride comfort. Using inappropriate or incompatible sizes can negatively impact vehicle stability, speedometer accuracy, and the lifespan of suspension components. Historically, original equipment manufacturers (OEMs) have conducted extensive testing to determine the most suitable sizes for each vehicle model, considering factors such as weight distribution, suspension geometry, and intended use.
