PNEUMATIC TIRE

PURPOSE: A pneumatic tire is provided to improve the durability and control stability of a tire by effectively designing the vulnerable part of a bead unit and improving the rigidity of the bead unit. CONSTITUTION: A pneumatic tire comprises a carcass(1), and inner and outer bead wires(4,5). The carcass is arranged to expand to a thread, a sidewall(2), and a bead unit(10). The inner and outer bead wires are arranged to the inner and outer sides of the carcass by sloping at the same angle as the carcass. The inner and outer bead wires are positioned to cross each other at the inner and outer sides of the carcass. The inner bead wires are positioned according to a vertical distance(h1) from a bead toe(9). The outer bead wire is positioned to have a wider interval towards the sidewall(S2) than towards the bead toe(S1). The interval of the outer bead wires towards the sidewall is dense compared to the interval of the outer bead wires towards the bead toe.
