How Can Incorrect Tire Pressure Lead to Increased Road Noise?
Incorrect tire pressure can lead to increased road noise due to altered tire shape, reduced contact with the road, and changes in tire tread design. These factors collectively affect how tires interact with the road surface, resulting in heightened noise levels.
-
Altered tire shape: Incorrect tire pressure can cause tires to bulge or flatten. When a tire is under-inflated, it becomes wider in contact with the ground. A study by the National Highway Traffic Safety Administration (NHTSA) in 2020 found that under-inflated tires lead to more significant deformation as they roll. This deformation increases rolling resistance and generates extra sound.
-
Reduced contact with the road: Proper tire pressure ensures maximum contact between the tire and the road surface. Under-inflated tires do not make optimal contact, leading to a situation where the tire hits the road unevenly. This irregular contact increases vibrations, which translates to heightened noise. Conversely, over-inflated tires may lead to less contact area, which can also result in increased noise levels due to higher pitch sounds created as the tire engages with surface imperfections.
-
Changes in tire tread design: Tires are designed with specific tread patterns to manage road noise. Incorrect pressure can lead to excessive wear on certain tread areas. A study by the Tire Industry Association (TIA) in 2021 indicated that uneven wear caused by improper inflation can create a breakdown in sound-dampening features of the tires. This leads to a louder ride as more noise (both from the surface and from the tire itself) is transmitted into the vehicle cabin.
Through these mechanisms, incorrect tire pressure significantly contributes to increased road noise, affecting both driving comfort and vehicle performance.
