Description

The Tire Patterns including 3D Zipper Slot and Kerf, which maximizes noise, snow and wet performance through 3D zipper slots and cuff application,

The present invention relates to a tire pattern capable of reducing noise and improving wet performance and eye friction performance.

In the conventional tire 1, the tread pattern of the tire 1 is formed of the block 2 and the groove 3, as shown in Figs.

As shown in Figs. 3 to 5, the block 2 of the conventional tire 1 is formed with the straight line 3a contacting with the groove 3, .

In addition, when the tread of the tire 1 is worn, the volume of the groove 3 is reduced, and the performance of discharging the water from the ground surface of the tire 1 is reduced, thereby reducing the performance on wet roads.

The tread pattern of the tire 1 is designed so as to improve eye running properties and braking performance. Uneven wear of the blocks occurs due to a difference in pressure generated when the tread pattern of the tire 1 touches the road surface, There is a problem in that it becomes large.
