What are the consequences of turning the steering wheel to the lock position?

The consequences of turning the steering wheel to the lock position: 1. Keeping the steering wheel at the lock position for a long time can damage the power steering structure; 2. When the steering wheel is at the lock position, the tie rod will be constantly pulled by the wheels, and the steering gear and rack will also remain under stress, accelerating the aging and deformation of these components over time; 3. If the steering is at the lock position, the suspension system will be under force in one direction, leading to wear and fatigue in the suspension's control arms and links over time; 4. Before the steering wheel returns to the center position, the tire's shoulder and part of the tread bear the force instead of the entire tread being in contact with the ground. Since the tire sidewall is relatively thin, prolonged friction can cause air leakage or even a blowout.
When I first started driving, I often turned the steering wheel to its full lock, thinking it was normal operation. However, one time I turned too sharply in the neighborhood, causing the tires to wear out extremely fast—I had to replace two tires in less than three months, costing me several thousand yuan. Later, a mechanic told me that doing this frequently can damage the steering system. For example, the power steering pump may experience excessive pressure, leading to oil leaks or overheating, and in severe cases, the entire steering gear might need replacement. Additionally, turning the wheel to full lock in rainy or snowy conditions can easily cause the car to lose control, posing significant safety risks. Now, I consciously leave a little margin and turn the steering wheel slowly when making turns. This has extended my tire lifespan and even improved fuel efficiency. I recommend that new drivers pay attention to this to avoid developing bad habits. Also, during regular maintenance, check if the power steering fluid is at the proper level.
