Why does the car still pull to one side even with correct wheel alignment data?
2 Answers
The reason why the car still pulls to one side even with correct wheel alignment data includes uneven tire wear, inconsistent tire pressure, and the steering angle sensor G85 not being in the zero position. Below is relevant information about wheel alignment: 1. Introduction to wheel alignment: Wheel alignment is based on the four-wheel parameters of the vehicle, adjusted to ensure good driving performance and a certain level of reliability. 2. The function of wheel alignment: Front wheel alignment includes four aspects: caster angle, kingpin inclination angle, camber angle, and toe-in. Rear wheel alignment includes camber angle and individual rear wheel toe-in. Collectively, front and rear wheel alignment is referred to as wheel alignment, commonly known as four-wheel alignment. The purpose of wheel alignment is to keep the car driving straight stably, make steering easier, and reduce wear on tires and steering components during driving.
I've been driving for over twenty years and have encountered many situations where the wheel alignment data was correctly adjusted but the car still pulled to one side. This is usually related to the tires. Uneven tire pressure is the most common cause—for example, if the left front tire has a few PSI less than the right front, the car will drift toward the lower-pressure side. Inconsistent tire wear can also cause this; if one side of the tires is significantly more worn, or has bulges or internal damage, even perfect alignment data won't help. Another factor is tire type—mixing different brands or using old and new tires together can lead to varying grip levels. I recommend first checking the tire pressure yourself to ensure all tires are consistent, using a tire pressure gauge. If the wear is severe, consider replacing the tires or performing a tire rotation. Drifting not only makes driving uncomfortable but also increases fuel consumption and safety risks, especially at high speeds where loss of control is more likely. Regular tire maintenance can prevent many issues—don't just rely on alignment data and assume everything is fine.
