What are the reasons for a car to pull to one side?

The main reasons for a car to pull to one side include the following: 1. Different tread patterns on the two sides or uneven tread depth. It is best to use the same type of tires for the entire vehicle. At the very least, the two tires on the front axle and the rear axle must be the same, and the tread depth must be identical. If the wear exceeds the limit, they must be replaced. 2. Unequal tire pressure on both sides. Unequal tire pressure will cause the tires to become different in size, which will inevitably lead to pulling to one side when rolling. 3. Deformation of the front shock absorber springs or inconsistent cushioning on both sides. The condition of the shock absorber springs can be judged by pressing or comparing after removal. 4. Failure of the front shock absorbers. After the front shock absorbers fail, the suspension on both sides will be uneven during driving, causing uneven force distribution and leading to pulling to one side. 5. Excessive wear or abnormal gaps in the vehicle's chassis components. Common parts prone to excessive gaps include the steering tie rod ball joints, control arm bushings, and stabilizer bar bushings. The vehicle should be lifted for a thorough inspection. 6. Poor brake release or separation of a certain tire can also cause the vehicle to pull to one side. 7. Overall deformation of the vehicle frame. If the wheelbase on both sides differs too much, exceeding the maximum allowable range, it can be measured with a tape measure. If it exceeds the range, it must be corrected using a correction platform. 8. During tire installation, the direction of the tread pattern was not noticed. Check if the tire tread direction was not considered during installation. If so, simply correct it.
Last time I drove, the car kept pulling to the right, which was really annoying. The most common reason is uneven tire pressure—just a few PSI difference between the left and right tires can cause it, especially in older cars where tire wear is uneven, leading to varying tread depths and different resistance levels. Wheel misalignment is also a key factor—if the four-wheel alignment data is off, with improper toe or camber settings, the car will drift as soon as you drive. Suspension system issues are also common, like leaking shock absorbers or deformed control arms, making the car unstable. Brake system faults, such as one-side calipers gripping too tightly or not retracting properly, can cause dragging. Road tilt or load imbalance, like heavy items placed on one side of the trunk, can also cause temporary pulling. Remember, don’t ignore pulling—regularly check tire pressure, perform alignment maintenance, and if needed, visit a professional shop to fix suspension or brake issues. My experience shows that annual maintenance helps avoid these troubles.
