The original equipment specification represents the manufacturer’s recommended dimensions for the vehicle’s tires. This specification impacts handling, fuel efficiency, and speedometer accuracy. For the specified vehicle model and year, this measurement is crucial for maintaining the vehicle’s intended performance characteristics. Deviation from the recommended value can lead to undesirable effects.
Adhering to the correct measurement ensures optimal performance, safety, and longevity of the tires. Historically, manufacturers have designated specific dimensions based on extensive testing and engineering considerations. Utilizing the correct specifications ensures proper load-bearing capacity and avoids potential mechanical issues related to incorrect fitment.
