Improper wheel alignment can lead to faster tire wear because when wheels are not aligned correctly, they do not point in the same direction or make optimal contact with the road. This misalignment causes uneven tire wear, where some areas of the tire wear down more quickly than others. As a result, the vehicle requires more frequent tire replacements, which increases overall maintenance costs and can compromise safety.

In contrast, a proper wheel alignment helps ensure that the tires wear evenly, optimizing their lifespan and performance. It also affects vehicle handling, fuel efficiency, and overall comfort, making correct alignment crucial for vehicle maintenance and safety.
