Why does the left rear wheel hit the left corner when reversing into the left parking space?

[StDaisy]

The specific reasons and solutions for the left rear wheel hitting the left corner when reversing into the left parking space are as follows: 1. Steering too early: If you start turning the steering wheel fully to the left before the lower edge of the rearview mirror aligns with the stop line, it can cause the left rear wheel to hit the left corner of the parking space. Solution: When you see the lower edge of the left rearview mirror align with the entrance line of the parking space, press the brake to stop the vehicle. 2. Keeping the steering wheel fully turned to the left: Before reversing into the parking space, you need to align the vehicle 1500-1800mm away from the road edge line (the distance between the car body and the road edge line should be 1500-1800mm), but it's not always possible to stop accurately every time. When you start reversing with the steering wheel fully turned to the left, observe the distance between the left rear wheel and the corner of the parking space in the left rearview mirror. If this distance is less than 300mm (less than 2 fingers in the mirror), you need to adjust the steering wheel to increase the distance. If you keep the steering wheel fully turned to the left, the wheel will hit the corner line. Solution: When reversing with the steering wheel fully turned to the left, if you see that the distance between the left rear wheel and the corner of the parking space is slightly less than 3mm, you can turn the steering wheel back half a turn. If the wheel is about to hit the corner, you can only straighten the steering wheel to increase the distance.

When I was learning to drive, I often hit the left corner during left reverse parking. The instructor said it was a steering wheel operation issue. Either I turned the wheel too early, before the car reached the entrance of the parking space, causing the wheels to scrape the corner; or I turned too late, making the car body tilt and unable to adjust, resulting in hitting the corner. Observation points are crucial—you need to watch the rearview mirror to see the position of the rear of the car. Ideally, you should slowly turn the wheel when the rear wheels are close to the corner. The speed should not be too fast either, or you won’t have time to react and will make more mistakes. Hitting the corner results in heavy deductions during the test. Practicing more in open spaces can improve your feel for it. I recorded videos with my phone to review my movements, and it worked well. Adjust your mindset and don’t get nervous—practice makes perfect. Repeatedly hitting corners may damage the tire edges, so regular checks are necessary.

When teaching reverse parking, I notice students frequently hit the left corner, mainly due to poor coordination between the steering point and speed. For example, turning too sharply after the car enters the spot, or starting too close to the parking space and directly hitting the corner. I advise students to watch the left rearview mirror and gently steer only when the parking corner appears in the mirror, leaving a safe distance. Maintain a steady speed, as going too fast can easily cause deviation. Using fixed reference points on the car can reduce errors, such as aligning the lower edge of the rearview mirror with the parking line before turning. Practice more on small turning radius operations. Hitting the corner not only deducts points but may also scratch the wheel rims. Remind them to regularly maintain tire pressure to prevent damage.

Pressing the left corner indicates that the steering timing was not accurate. I've noticed that most beginners misjudge the reference points, such as turning the wheel too early when the front of the car is too close to the parking space, causing a direct collision with the corner. It's better to turn the wheel slightly earlier to allow the car to enter the space at an angle, while using the rearview mirror to monitor the distance between the wheels and the corner. Practicing at a slower speed makes it easier to correct mistakes, and avoid sudden steering wheel movements. Frequent corner pressing may lead to faster tire wear, so regular tire pressure checks are essential. With more practice and experience, you'll naturally avoid this mistake over time.

From a physical perspective, pressing the left corner usually indicates a miscalculation of the turning radius. When reversing, if the steering is turned too sharply to the left, the vehicle's inner wheel trajectory becomes smaller, making it easier to hit the corner of the garage. The size of the vehicle and the garage space also play a role, with smaller cars having more adjustment room. It is recommended to align the front of the car with the entrance and steer gently while controlling the speed to allow the rear wheels to avoid obstacles. Practice geometric positioning methods, such as using rearview mirrors or ground markers as references. If the corner is pressed, stop promptly and make slight adjustments to the steering to prevent wheel damage.

Reversing into the corner not only involves operational errors but can also damage the car body. I've seen a friend's wheel rub against the side, which requires checking if the starting position is incorrect or if the steering wheel is misaligned. Use radar or camera assistance to observe angles while reversing slowly to avoid hard contact with the warehouse edge. Long-term corner pressure may damage tires or even the suspension, so it's recommended to have the steering system checked at a shop. Always look back to confirm safe distances, mark reference points during practice to reduce mistakes, and ensure smooth driving to protect the vehicle.
