| 摘要 |
The present invention relates to a pneumatic tire which includes a plurality of protrusions which are inclined in the central direction of the tire relative to the circumferential direction of the tire and opposite protrusions on the inner side of the vertical grooves. The tire according to the present invention increases the speed of water current and controls the direction of the water current by generating the vortex phenomenon of water inside the vertical grooves. Therefore, the tire improves wet performance due to improved drainage performance, is favorable for heat emission due to increased contact surface due to the patterns inside the grooves, and improves driving stability. |
