What is the steering angle between the steering wheel and the wheels?

The steering wheel typically rotates 540-630 degrees from the center to one side, corresponding to a wheel turn of approximately 40-42 degrees. For every 13-16 degrees of steering wheel rotation, the wheels turn by 1 degree. One full rotation of the steering wheel results in a wheel turn of about 25 degrees. When the car's steering tires and the body are perfectly aligned, the steering wheel is at 360°, and the steering tires are at 45° because the steering tires can only turn up to 45° left or right. Steering wheel techniques: For a left turn, first activate the left turn signal, use your left hand to turn the steering wheel to the left, and assist with your right hand to push it left. After the turn, use your right hand to turn the steering wheel back to the right to align the direction straight. For a right turn, first activate the right turn signal, use your right hand to turn the steering wheel to the right, and assist with your left hand to push it right. After the turn, use your left hand to turn the steering wheel back to the left to align the direction straight. For continuous curves, the key is to reduce speed. Before entering the curve, slightly lean to the right. If turning right, lean slightly to the left. The exact number of steering wheel rotations depends on the actual situation.
When it comes to steering wheel and wheel turning angles, I've been driving for over 20 years and am quite familiar with this. In a standard sedan, the steering wheel typically turns about 360 degrees in one full rotation, while the wheel turning angle is a reduced version of the steering wheel angle, known as the steering ratio, usually around 15:1 to 20:1. Simply put, for every 15 to 20 degrees you turn the steering wheel, the wheels move just 1 degree. This design makes driving more effortless, especially during low-speed parking, where you don't need to exert much force to turn; it also enhances stability at high speeds, preventing the car from drifting due to minor steering adjustments. Different vehicle models have varying ratios—for example, SUVs might have a slightly higher ratio, around 18:1, due to their higher center of gravity and less stability, requiring more careful steering. My own car has a standard 15:1 ratio, and turning feels exceptionally smooth. If the ratio is abnormal—say, the steering wheel turns too much while the wheels move too little—it might indicate a steering gear issue, so it's best to get it checked and not overlook safety.
One of the joys of driving lies in the sense of control, where the wheels respond as soon as the steering wheel turns, typically with a ratio between 15:1 and 20:1. I mostly drive urban commuter cars, where the steering ratio is designed to balance control and safety: if the ratio is too direct, like 10:1, where a small turn of the wheel results in a large wheel movement, the car can become unstable at high speeds; if it's too slow, making turns becomes laborious. Most modern cars have a ratio around 16:1, allowing you to change lanes at high speeds with just a slight twist—very agile—while also reducing the chance of skidding during low-speed turns. Interestingly, vehicle speed affects steering: at high speeds, the system automatically makes the steering ratio more indirect to maintain stability, while at lower speeds, it becomes more direct to facilitate parking. This is all thanks to gear transmission, but don’t worry—it’s simple and reliable. Pay attention to the steering ratio during driving; if the wheel feels unusually loose or tight, it’s time for maintenance. Proper upkeep can extend your car’s lifespan.
