What is the effect of the tires on the car tires?
Increased roughness with the ground contact surface had a big friction
Look at it, you will find the car tires have such a pattern. This is not to look good, but to ensure the safety of vehicles driving. Why do you say this way? If the car is only on a very dry road, the tires do not pattern is also very safe. Can be a rainy day, no pattern tires are easy to slip, this is because there is a thin layer of water film between the road and the tires, water film to reduce the friction between the tire and the road. At this time, the car will be staggered to open up, would like to stop but not stop. If the tires are patterned, the water will drain from the groove of the pattern, and the tires and the ground are still tightly attached together, so it is not easy to slip. Vehicles in the city, tires on the pattern are generally straight jagged, it can help eliminate the car when the noise emitted. In the field of vehicles, tires on the pattern is deep and wide, can be tightly "bite" live on the ground, even in the snow, not easy to slip.
Each tire brand design will be different. The same brand of tires, different patterns represent different product positioning. Different specifications to choose the pattern is not the same.
