How does tire pressure affect the wear pattern on tires?

Tire pressure plays a crucial role in determining the wear pattern on tires. Incorrect tire pressure can lead to uneven wear, reducing the lifespan of the tires and affecting their performance.

When tire pressure is too low, the tire's sidewalls can flex excessively. This increases the rolling resistance and generates more heat, causing the tire to wear more quickly on the outer edges. Low tire pressure also leads to increased friction, which can result in uneven wear patterns across the tire tread. The center of the tread may remain relatively unworn, while the edges wear out prematurely.

Conversely, overinflated tires have decreased contact with the road surface. This leads to uneven wear patterns on the center of the tire tread, while the edges experience less wear. Overinflation puts excessive stress on the tread, causing it to wear out faster in the middle. It can also make the tire more susceptible to damage from road hazards and decrease handling performance.

Therefore, maintaining the correct tire pressure is essential to ensure even wear across the tire tread. By following the manufacturer's recommended tire pressure, drivers can optimize the tire's performance, increase its longevity, and maintain proper handling and braking capabilities.
