The specific dimensions of the rubber encircling the wheels of a mid-size sedan, such as the Toyota Camry, are crucial for vehicle performance and safety. These numerical designations, typically found on the tire sidewall, indicate width, aspect ratio, and wheel diameter, influencing factors like handling, ride comfort, and fuel efficiency. For example, a common specification might be 215/60R17, representing a tire with a 215mm width, a sidewall height that is 60% of the width, and designed to fit a 17-inch wheel.
Adhering to the recommended specifications, as outlined in the vehicle’s owner’s manual or tire placard, ensures optimal handling, braking performance, and speedometer accuracy. Deviating from these guidelines can impact the vehicle’s stability control system, potentially compromising safety. Historically, these measurements have evolved to accommodate advancements in vehicle design and consumer demand for improved comfort and performance characteristics.
