The present invention relates to a tire groove structure which can minimize groove cracks by maintaining a depth of an outermost groove equal to or less than 85% of a depth of a main groove to minimize a deformation rate and, at the same time, maintaining a function of a pattern to a maximum state, and maintaining a safe distance between an end of a second belt and a inflection point of a groove equal to or higher than 35% of a tread width to minimize the inflection point of a groove from stress generating at the end of the second belt. |
