Summary: | The present invention provides a pneumatic tire including a tread block 10 having a sipe 100 formed therein. A three-dimensional inclined surface groove 110 is formed at an upper portion of the sipe 100 formed in the tread block 10, such that three-dimensional inclined surface protrusions 16 and inclined surface grooves 17 respectively formed on both sipe side wall surfaces 15 forming the sipe 100 so as to correspond to each other may minimize a movement of the tread blocks 10 due to a stress generated from the tire contacting with a ground during driving, so as to increase a traction force. In addition, a lower through groove is formed at a lower portion of the sipe 100 formed in the tread block 10, such that it is possible to reduce a resonance noise of the tire occurring when driving, more easily and automatically discharge the foreign matters caught in the sipes 100 of the tire during driving, and improve a traction performance of the tire in the latter half of the tire lifespan by dividing the remaining tread block 10 after the upper portion of the tread block 10 is worn. |
