PURPOSE: A rim for a tire including a bead unit is provided to reduce a deviation of actual vehicle performance when the tire and the rim are connected and to prevent additional accidents caused by the separation of the tire from the rim when the tire is punctured. CONSTITUTION: A rim for a tire (1) including a bead unit is comprised by mounting the bead unit on a rim flange (2). A bead protrusion unit (5) is integrally formed in a base (3) of the rim flange. The bead protrusion unit is inserted into a bead insertion groove (4) of the tire. The bead protrusion unit has a protruding distance (l) within 30-50 % of the distance (L) to a round knee point (R) of the rim flange based on a base surface and a diameter (d) within 40-70 % of the base width (D) of the rim flange. |
