What is the purpose of car wheel alignment?

[SanPreston]

The functions of car wheel alignment are as follows: 1. It ensures the straight-line stability and handling performance of the vehicle. 2. It improves the steering response and ensures the returnability of the steering system. 3. It prevents improper bearing stress and damage, as well as loss of precision. 4. It ensures tight contact between the tires and the ground, reduces abnormal tire wear and irregular tread wear, and ensures stability during cornering. The conditions for car wheel alignment are as follows: 1. Tire pressure and tire tread wear: Uneven tire wear indicates a fault in certain aspects such as the tires, steering system, or suspension. 2. Wheel wobble: Wobble is a condition where the tire rotates unstably due to various reasons, and it refers to irregular up-and-down or left-and-right movement of the wheel and tire. 3. Wheel misalignment: Misalignment refers to the situation where the vehicle deviates from its intended direction while driving on a straight road, with the steering wheel not subjected to any external force.
