Disclosed is a tubeless tire having a reinforced bead portion capable of reducing the stress applied to a portion contacting a rim flange and to an edge of a carcass. The tubeless tire includes a carcass turned up around a bead core, a bead filler filled in a space above the bead core surrounded by the carcass, a steel chafer disposed to contact an outer surface of the carcass, and a first reinforcing rubber layer provided between the bead core and the carcass in order to prevent a turnup portion of the carcass from being pulled downwards, the first reinforcing rubber layer being located around a portion of the bead core that is oriented toward a rim flange. The bead portion is improved in durability under a high-pneumatic-pressure condition by reducing the stress applied to interfaces of the edge of the carcass, the steel chafer and the nylon chafer.
