It is not enough to get a good performance tire just with rubber formula, also need special function design on tire pattern. Tire pattern is one of the most complicated factors with tire design, and also very important.  Tire pattern not only decide on using character with tire, but also decide on tire grip the ground performance, drainage performance and noise.

We also can know the tire is more inclined to which function through the tire pattern or shape of glue block. For example, if the glue block of pattern is large, so this kind of tire should be more inclined to grip the ground; if the glue block is more, small and many groove, so this kind of tire should be more inclined to drainage; if  the glue of pattern on both sides of the line is properly malposed, it will help reduce the noise. We talk about winter tire, the pattern is jagged.

This kind of jagged designs are similar to some of pets sole of the feet such as cat and dog, you can find it have very strong force of friction when you touch it. This is the reason why pets can run around on the smooth tile at home. Snow tire get this kind of zigzag pattern can enhance performance of grip the ground.
