When the truck is driving on a rainy road at high speed, a thin layer of water film will be formed between the tire and the road surface. In order to increase the contact between the tire and the ground, several water guide grooves will be set in the longitudinal direction of the tire to provide effective protection for the tire. drain. The three or four longitudinal grooves on the surface of the tire are called water guide grooves, and their main function is to drain water. The more longitudinal water guide grooves, the better the drainage effect and the better the stability of the tire in rainy days. The more water guide grooves, the better. Too many water guide grooves will reduce the contact area between the tire and the ground and weaken the grip of the tire. In addition to the vertical water guide grooves, there are many horizontal patterns on the tire surface to cooperate with the water guide grooves to drain water and break the water film formed between the tire and the ground, increasing the friction between the tire and the ground.
When the tires are driving on a slippery road at high speed, if the grip of the tires is insufficient, the vehicle can easily lose control. For master truck drivers, there are two tips: first, don’t wait until the pattern is polished before changing the tires. Skating, braking is very difficult. One is to slow down on slippery roads, especially in rainy and snowy weather.
According to the old driver, there are still many differences between the three-ditch tires and the four-ditch tires. They have their own advantages and disadvantages in terms of tire grip performance, drainage performance and even fuel consumption. Choosing the right tire can increase and optimize the driving experience, but choosing the wrong tire will not mention the driving experience, and even driving safety will be threatened, so it is necessary to understand this knowledge.
