The specification detailing the dimensions of the rubber component fitted to the wheels of a specific model-year vehicle is a critical piece of information. As an example, the original equipment for the referenced hybrid car is commonly 195/65R15. This alphanumeric designation provides details regarding width, aspect ratio, construction type, and rim diameter.
Proper adherence to the designated specification is vital for maintaining the vehicle’s handling characteristics, fuel efficiency, and speedometer accuracy. Deviations from the factory recommendation can negatively impact performance and safety. Historically, these specifications have evolved alongside advancements in tire technology and vehicle design, reflecting a focus on improved ride quality and reduced rolling resistance.
