What's the reason for sudden car deviation?
2 Answers
Sudden car deviation is caused by tire damage. The following are specific reasons for tire damage: Incorrect four-wheel alignment: Including insufficient front wheel camber angle and toe angle, etc., these can cause the car tires to operate unevenly, leading to deviation. Uneven tread wear: Prolonged driving and different road conditions can cause varying degrees of tread pattern wear. After wear occurs, the friction coefficients of the tire treads become inconsistent, resulting in uneven tire speeds at different angles, which naturally causes the car to deviate. Uneven tire pressure: Related to the car's driving mileage, the position of the tires can cause uneven tire pressure consumption. Tire shape: Due to differences in materials, manufacturing processes, and technology, it is difficult for tires to achieve a perfect circular shape. This can lead to vibrations and deviation, affecting comfort and safety.
I know exactly what you mean about sudden car pulling. Last time I was driving on the highway, my car noticeably veered to the right—it felt like being tugged sideways. I immediately slowed down and pulled over. There could be various reasons: the most common is uneven tire pressure, especially when front tires have different pressures, which directly affects steering feel. Or there might be a slow leak; in my case, I found a nail in the right front tire. Other causes could be loose steering linkage or worn suspension components, as rough roads accelerate wear. My advice is to safely pull over first, check tire pressure visually for punctures or bulges. Don't force it to avoid further damage or danger—better get a professional inspection for alignment. Regular tire maintenance prevents many surprises.
