What issue often arises due to underinflated tires?

Underinflated tires create several issues that can impact vehicle performance, and one major concern is excessive tire wear on the edges. When tires are not properly inflated, they tend to deform more than they should. This deformation leads to increased surface contact on the outer edges of the tire rather than along the center, thus causing uneven wear patterns. Over time, this uneven wear can significantly reduce the lifespan of the tires and may also affect the vehicle's handling and safety.

Additionally, while options like increased fuel consumption and traction on wet surfaces are indeed concerns associated with underinflated tires, the primary and more immediate issue observed is the wear pattern that develops. Therefore, the focus on edge wear due to insufficient inflation underscores the importance of regularly checking and maintaining proper tire pressure for overall vehicle maintenance and performance.
