Provided is a tire having a bead unit profile structure. According to one embodiment of the present invention, to improve lateral rigidity, the tire having the bead unit profile structure of the present invention comprises: a tread unit; a side wall unit; and a bead unit (10). In the bead unit (10), a range of an X coordinate from a coordinate origin (O), which is an European Tire and Rim Technical Organization (ETRTO) commercial rim standard reference point of an outermost point (P) of the bead unit in contact with a rim of a wheel, is 8.8 to 9.7 mm, and a range of a Y coordinate from the same is 19.2 to 21.7 mm. Provided is the tire having the bead unit profile structure to improve the lateral rigidity, with improved handling performance.
