What is the typical effect of improper wheel alignment on tire wear?

Improper wheel alignment typically leads to uneven tire wear, which can manifest as excessive wear on one edge of the tire compared to the other. When the wheels are not aligned correctly, they may point in slightly different directions or may not be parallel, causing tires to scrub against the road surface improperly. This scrubbing action increases friction and results in tires wearing down more rapidly on one side or at an angle, rather than wearing uniformly across the tread.

In addition to causing uneven tire wear, improper alignment can also have other effects, such as poor handling, decreased fuel efficiency, and compromised traction. However, the primary and most immediate impact is on the wear of the tires themselves, as the misalignment exacerbates the stresses on the tire's structure and tread. Regular alignment checks and adjustments are essential to ensure that tires wear evenly and to prolong their lifespan, as well as to maintain the vehicle's overall safety and performance.
