Is it normal for the rear wheel to slip and sway at high speed in rainy days?

Not normal. Rear wheel slip means that the rear wheel is the driving wheel and the vehicle is driven by the rear wheel. Slipping and swinging the tail in rainy days means that the rear wheel loses its grip. It is suspected that the tire pattern is excessively worn, the drainage effect is not good, and the rear wheel floats. It is recommended to replace the tires or cross the front and rear wheels.

Because of the four-wheel drive, when one wheel slips, the electronic system will give a braking force, while the other wheel still has power, which may lead to a short tail swing, which may be a shortcoming of the electronic slip-limiting system. However, in rainy and snowy days, four-wheel drive is safer than two-wheel drive, and a slight tail flick is generally not out of control. After all, the four-wheel drive will immediately pull the vehicle back to normal driving.

It is the reason why there is a water film between the tire and the ground, especially when the speed is fast, the tire tread can't drain water (the contact surface between the tire and the ground is actually very small), which leads to the lateral movement of the vehicle, just like playing with water with a flat stone. Only when the speed of the stone is fast, the water ticket will be drawn out and the power of the stone will not fall into the water. 4 The original small tires pay attention to the dry road performance, and the drainage is not very good, so this situation you will encounter will happen, and then there will be: rainy days, the water on the road is deep. Under such conditions, your speed is too fast and dangerous.
