Why Does a Car's Steering Wheel Pull to One Side?

[StKira]

The reasons for a car's steering wheel pulling to one side include the following: 1. Uneven tire pressure on both sides: The higher the tire pressure, the smaller the contact area with the ground, resulting in less rolling resistance. The vehicle will tend to pull toward the side with relatively lower tire pressure. 2. Uneven tread wear on both sides: The tire surface has a layer of rubber tread with a certain thickness. As the vehicle is used, the tread thickness gradually decreases. A tire with more tread wear effectively has a smaller diameter, causing the vehicle to pull toward the side with more tread wear. 3. Poor brake caliper piston retraction on one side: If the brake piston on one wheel does not retract properly, it will increase the rolling resistance on that side, causing the vehicle to pull toward the side with higher resistance. 4. Incorrect wheel alignment: If the camber angles of the wheels on both sides are inconsistent, the vehicle will tend to pull toward the side with a larger outward tilt angle.
