How to prevent car tires from slipping in winter? What is the reason for the front wheels to slip when the car starts in rainy days?

Car tires have deep grooves, so they have great friction with the ground and can grip the ground well. But if it rains or snows, it is easy to slip. So how can we prevent slipping?

How to prevent car tires from slipping in winter

Replace the snow tires. Snow tires have many grooves and good drainage performance. Snow tires have at least 1,000 small grooves, while ordinary tires only have 200. The material of snow tires is also softer than ordinary tires. The shoulders of winter tires also have a unique design. The angle shape of the tire shoulder design increases the grip between the tire and the ground.

Before driving out, prepare anti-chemical tools, such as shovels, pickaxes, anti-skid chains, etc. When driving, it is best to choose a place where the vehicle in front has passed or a safe route to pass. When starting the vehicle, give a small amount of gas to adapt to the smaller grip and prevent the wheels from slipping.

When the vehicle is going uphill, do not stop to prevent it from skidding. When you need to accelerate, increase the speed slowly and do not over-accelerate. When you need to slow down or stop downhill, you should brake predictably and use the manual brake at the same time. It is strictly forbidden to use high-speed to slide downhill to prevent side slipping.

Keep a certain distance from pedestrians and other vehicles while driving. When turning, increase the turning radius to prevent skidding.

Why does the front wheel slip when the car starts in rainy days?

This is a very common phenomenon.

First of all, there is water on the ground on rainy days, and the accumulated water will form a layer of water film between the tires and the ground. This layer of water film will prevent the tires from directly contacting the ground, but will separate them with a layer of water. Naturally, the grip will be worse than when it is dry.

Secondly, when the vehicle starts, the center of gravity moves backward, the rear wheels are under greater pressure, and the front wheels are subjected to less gravity. Therefore, the friction force when the front drive starts is less than the friction force when stopping, so the friction force is insufficient and the tires are in an idling state.

Another factor is the road conditions. For example, it is easy to slip on the road where there are zebra crossings, but it is not easy to slip on asphalt roads.

What to do if tires slip on sand and gravel

When the car is passing through gravel or slippery roads, the speed should be controlled within 30 kilometers per hour. If slipping occurs, you can do the following:

1. Slowly turn the steering wheel in the direction of the slide. This will increase the turning radius, effectively reduce the centrifugal force, and make the car stable. Be careful not to turn the steering wheel sharply in the opposite direction, as this will have the opposite effect and may turn the side slide into a spin or rollover.

2. Release the accelerator and use the inertial resistance of the engine to slow down. After the speed is reduced, the skidding tendency can be effectively alleviated. Do not brake suddenly, which will only make the skidding worse and the vehicle completely out of control.
