ABSTRACT:
A pneumatic tire having an improved heel structure includes a two element rubber filler assembly extending from a bead core toward the tread, generally decreasing in thickness in a direction away from the bead core. One of the filler elements is reinforced rubber having a Shore A hardness between 85.degree.-93.degree. whereas the other filler element, in mutual contact with the first, is nonreinforced rubber having a Shore A hardness between 70.degree. to 95.degree.. The contact surface between the two filler elements forms an oblique angle with the equatorial plane of the tire.
