The specified inflation level for a vehicle’s pneumatic wheels is a critical parameter affecting its performance, safety, and longevity. For a mid-size sedan from a particular Japanese manufacturer, this value is typically indicated on a placard located on the driver’s side doorjamb or in the vehicle’s owner’s manual. This recommendation reflects extensive engineering analysis to optimize handling, fuel efficiency, and ride comfort for that specific model.
Maintaining the correct inflation provides numerous advantages. Appropriate pressure contributes to even tread wear, extending the lifespan of the tires. It also optimizes the contact patch between the tire and the road surface, which is essential for effective braking and cornering, enhancing overall vehicle safety. Furthermore, it minimizes rolling resistance, leading to improved fuel economy and reduced emissions. Historically, underinflation has been a significant contributor to tire failure and accidents.
