How does tire pressure affect the wear pattern of a tire?

Tire pressure plays a critical role in determining the wear pattern of a tire. Proper tire pressure helps to ensure optimal contact between the tire and the road surface. When the tire is inflated to the recommended pressure, it distributes the vehicle's weight evenly across the tire's surface area. This even distribution of weight helps the tire to wear more evenly.

On the other hand, when tire pressure is too high, the center of the tire tends to carry the majority of the vehicle's weight. This results in accelerated wear in the center area of the tire, creating a wear pattern commonly known as "center wear." Conversely, if the tire pressure is too low, the tire sidewalls bear a greater portion of the weight, leading to excessive wear on the outer edges of the tire, known as "shoulder wear."

In addition to causing uneven wear patterns, incorrect tire pressure can also impact the handling and performance of the vehicle. Underinflated tires increase rolling resistance, which can negatively affect fuel efficiency and handling. Overinflated tires, on the other hand, can reduce traction, making it harder to control the vehicle, especially in wet or slippery conditions.

To prevent uneven wear patterns and ensure optimal tire performance, it is essential to regularly check and maintain the recommended tire pressure. This can be done by referring to the vehicle manufacturer's recommendations or consulting the tire manufacturer's guidelines.
