The recommended inflation level for tires on a specific model of luxury SUV is a critical parameter affecting vehicle performance and safety. This value, typically measured in pounds per square inch (PSI) or BAR, dictates the contact area between the tire and the road surface. For instance, a value of 32 PSI might be indicated on the door placard of a particular vehicle.
Maintaining the appropriate inflation ensures optimal handling, braking, and fuel efficiency. Underinflation can lead to increased tire wear on the shoulders, reduced fuel economy, and a higher risk of tire failure due to overheating. Conversely, overinflation can result in a harsher ride, decreased grip, and uneven wear in the center of the tire. Historically, manufacturers have refined these recommended pressures through extensive testing to balance performance characteristics with safety and comfort.
