Abstract
The present invention provides a pneumatic tire including a tread blockhaving a sipeformed therein. A three-dimensional inclined surface grooveis formed at an upper portion of the sipeformed in the tread block, such that three-dimensional inclined surface protrusionsand inclined surface groovesrespectively formed on both sipe side wall surfacesforming the sipeso as to correspond to each other may minimize a movement of the tread blocksdue 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 sipeformed in the tread block, 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 sipesof 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 blockafter the upper portion of the tread blockis worn.
