What is the difference between three grooves and four grooves in a car tire?

In daily travel, it is inevitable to encounter bad weather. When encountering heavy rain, the road surface will become extremely slippery, so the tires will also be affected. Because at this time, a water film will form between the slippery road surface and the tires, so the tires will slip. This groove can also be said to be a guide channel. The main purpose of the design of the guide channel is to effectively drain the tire and enhance the stability of the tire. So compared to tires with three grooves and tires with four grooves, of course tires with four grooves have better drainage performance. Those tires with deeper and more tread patterns on the market also have relatively better water drainage.

Driven by the power of the engine, the car gives friction to the ground through the tires. At this time, the ground produces a reaction force, thus pushing the car forward. This is how cars drive, so this friction is grip. There are many factors that affect road grip, and tires are one of the most important factors.

The larger the contact area between the tire and the ground, the greater the grip. Compared with tires with four grooves, tires with three grooves have a larger contact area with the ground. Therefore, in terms of grip performance, tires with three grooves are better.

Since four-groove tires have one more groove than three-groove tires, there will be more gravel, broken glass and other debris mixed in the grooves. In fact, these debris are slowly wearing down the car tires, and they will become very difficult to deal with over time. Therefore, this will also have a certain impact on the life of the car tires. If a tire blowout occurs, the consequences will be disastrous, so we car owners must perform daily maintenance to prevent accidents.
