A few days ago, many places in southern my country have experienced large-scale and high-intensity precipitation weather, and most parts of the country are currently entering the flood season. Many car owners are considering changing to a better wet tire product.

We all know that the drainage capacity of the tire is the key to determining the anti-skid performance of the tire in the rainy environment, and it is also the guarantee of the wet performance of the tire.

When the tires are driven on rainy roads at high speed, a thin water film will be formed between the tires and the road surface, which is easy to slip.

Therefore, in order to increase the contact between the tread and the ground, all tires will be provided with several water guide grooves in the longitudinal direction to effectively drain the tires, which is commonly known as tire drainage grooves.

Are more tire gutters better for wet performance?

When purchasing tires, we found that some tires are designed with 3 longitudinal grooves, and some are designed with 4. So, is the wet performance of tires with four drains better than three?

In terms of drainage performance, yes. After all, one more groove means that the tire can discharge more water when it is rolled to the water, and it is better to avoid the generation of water film between the tire and the ground.

But more gutters doesn't necessarily mean better wet performance of your tires.

In addition to the drainage capacity, another key factor in the wet performance of the tire is the grip, and the grip mainly depends on the contact area between the tire and the ground.

A tire with the same tire width has an extra drain, which means that part of the tire's ground contact area is sacrificed and part of the grip is given up. Therefore, the number of drains and the wet grip of the tire are actually a set of contradictions.

In addition, more drains also means that the tires are more likely to "eat stones", which is more likely to shorten the life of the tires.

How to choose tires with good wet performance in summer

As for whether to choose 3 grooves or 4 grooves, Xiaobang suggests that the majority of car owners should not be entangled. In the product design stage, the manufacturer will design the number of drainage grooves according to the tire width and comprehensive performance. There are certain considerations and scientific reasons for the choice of 3 or 4 drainage grooves for the product.

Therefore, when car owners choose tires, they should first check whether the size of the tire matches the size of the hub of the car. Wheeled cars are not suitable.

Secondly, it should be determined according to the owner's summer rainwater environment. If the car owner uses the car with frequent local summer rains and the road water volume is large, it is more appropriate to choose tires with more drainage grooves; if the situation is the opposite, choose tires with 3 drainage grooves. It is also enough to support the safe driving of the car in the light rain environment.

Finally, the selection of tires should consider the comprehensive performance complement of the car and the service life of the tires. Although the wet performance is an important performance of the tires, it is not necessary to be too obsessive and ignore the consideration of other factors. When purchasing tires, it is also important to explain your own needs for tires and listen to the opinions of professionals.
