A few days ago, many parts of southern China experienced large-scale and high-intensity precipitation weather, and most parts of the country are also entering the flood season. Many car owners are considering changing to a wetland tire product with better performance.
We all know that the drainage capacity of tires is the key to determining their anti slip performance in rainy environments, as well as ensuring their wet performance. When the tires are driving at high speed on rainy roads, a thin film of water forms between the tires and the road surface, which is prone to slipping. So, in order to increase the contact between the tread and the ground, all tires will be equipped with several guide channels in the longitudinal direction to effectively drain the tires, which is commonly known as the tire drainage ditch.
When selecting tires, we found that some tires were designed with 3 longitudinal grooves, while others were designed with 4 grooves. So, is the wetland performance of tires with four drainage ditches stronger than three? In terms of drainage performance, yes. After all, having an extra groove means that the tire can discharge more water when it is rolled over to accumulate water, better avoiding the formation of water film between the tire and the ground. However, the more drainage ditches there are, the better the wetland performance of the tires will not necessarily be.
In addition to drainage capacity, another key factor for tire wetland performance is grip, which mainly depends on the contact area between the tire and the ground. For tires with the same tire width, having an additional drainage ditch means sacrificing some of the tire's touchdown area and giving up some of its grip. Therefore, the number of drainage ditches and the tire's wet grip are actually a set of contradictions.
In addition, having more drainage channels also means that tires are more likely to eat stones and shorten their lifespan. As for whether to choose three or four channels, Xiaobang suggests that car owners should not hesitate. In the product design stage, manufacturers will design the number of drainage channels based on tire width and comprehensive performance. Whether to choose 3 or 4 drainage channels for the product is based on certain considerations and scientific principles.
So, when choosing tires, car owners first need to check whether the size of the tires matches the size of their car's wheels. Don't blindly choose this type of tire just because there are too many drainage channels. Tires with too many drainage channels may have wider tread, which is not suitable for cars with narrow wheels.
Secondly, it should be determined based on the vehicle owner's summer rainwater environment. If the vehicle owner's local area has frequent summer rainfall and a large amount of water on the road, it is more appropriate to choose tires with more drainage ditches; If the situation is the opposite, choosing tires with three drainage channels is enough to support your car's safe driving in light rain environments.
Finally, the selection of tires should consider the comprehensive performance of the car and the service life of the tires. Although wet performance is an important performance of tires, there is no need to be too persistent and ignore other factors. When choosing tires, it is also important to explain your needs for tires and listen to the opinions of professionals.
