When a car should undergo four-wheel alignment: New cars should have their four-wheel alignment checked after 3 months of driving, and subsequently every 10,000 kilometers traveled, after tire rotation, and after a collision. Four-wheel alignment is based on the four-wheel parameters of the vehicle, adjusting them to ensure good driving performance and a certain level of reliability. Four-wheel alignment improves driving safety, reduces tire wear, keeps the steering wheel straight when driving straight, maintains straight-line driving, allows the steering wheel to automatically return to center after turning, enhances driving control, reduces fuel consumption, and decreases wear on suspension components.

After driving for so many years, I've learned that wheel alignment should be done in specific situations: when the steering wheel keeps pulling to one side, when the inner or outer edges of the tires wear excessively, or right after installing new tires. For example, I often feel the steering isn't straight after long-distance trips, so I go for an alignment check. Alignment is also necessary after replacing suspension components or hitting potholes to ensure parameters are reset. Regular preventive checks every 15,000 km or annually can prevent premature tire wear and save fuel. Last week, I delayed addressing it, and my tires were ruined in just three months, costing me a lot of unnecessary money. Developing this habit also improves driving stability, making highway driving much more reassuring.

In car repair scenarios, I believe the appropriate times for wheel alignment include when the vehicle pulls to one side, irregular tire wear occurs, after replacing rims or shock absorbers, and following any collision impact. Regular alignment every 20,000 kilometers can prevent excessive stress on the steering system and extend its lifespan. Misaligned parameters can accelerate wear, leading to steering gear damage or increased fuel consumption. I once neglected this and the car owner complained about a loss of control feeling; fortunately, addressing it early prevented major issues. From an economic perspective, an alignment costs just a few dozen yuan but can save thousands in replacement costs for a full set of tires, making it a very cost-effective measure.

During my novice period, I encountered the issue of the steering constantly pulling to the right. After searching online, I learned that a wheel alignment was needed. Typically, an alignment is required after installing new tires, experiencing excessive vehicle bouncing, or noticing uneven tire wear. The inspection is quick and straightforward, immediately improving steering precision. Since then, I've had it checked every 10,000 kilometers to prevent minor issues from escalating. Learning this made long-distance driving much more relaxing, as I no longer had to worry about the car veering off course. Regular saves money that can be spent on fuel, which is quite practical.

From a cost-saving perspective, I recommend getting a wheel alignment whenever there's abnormal tire wear or steering instability. Investing a small amount in alignment when installing new tires can extend their lifespan by six months, avoiding replacement costs. Neglecting it may increase fuel consumption by 10-20% and accelerate part wear. After an accident, I had mine aligned and saved thousands in subsequent repairs. It's advisable to do it every 8,000 km or annually—far more economical than premature tire replacement.

From a safe driving perspective, I believe wheel alignment should be performed when the car exhibits steering wheel vibration, instability at high speeds, or poor tire grip. The safest approach is to check alignment after accidents, following suspension repairs, or every 15,000 kilometers. Improper alignment may cause skidding on wet roads and unresponsive steering, increasing accident risks. I once experienced loss of control in rainy conditions and was fortunate to handle it timely. Developing alignment habits can be lifesaving, reducing road accidents - especially crucial before long trips.
