How does tire pressure affect tire wear pattern?

Proper tire pressure plays a crucial role in maintaining a consistent tire wear pattern. When the tire pressure is too low or too high, it can lead to uneven tire wear and shorten the lifespan of the tires.

When tires are underinflated, the tire's sidewalls tend to flex excessively. This causes the tire to wear more on the outer edges, known as shoulder wear. Additionally, underinflation increases the tire's rolling resistance, which can result in increased fuel consumption.

On the other hand, overinflated tires have a smaller contact patch with the road. This causes the center of the tire to bear most of the load, leading to excessive wear in the center of the tire, known as center wear. Overinflation can also make the ride harsher and reduce traction, particularly in wet conditions.

To ensure optimal tire wear pattern, it is essential to maintain the manufacturer-recommended tire pressure. Regularly checking and adjusting tire pressure helps to distribute the vehicle's weight evenly on the tires, minimizing uneven wear and improving tire longevity. Additionally, maintaining proper tire pressure enhances fuel efficiency, vehicle handling, and overall safety.
