The invention discloses an aviation tire with a tire bead reinforcing rubber and a formula of the reinforcing rubber. The aviation tire comprises a tread rubber, a reinforcing layer, a carcass cord fabric layer, an air barrier and a sidewall rubber, as well as a tire bead reinforcing rubber layer; the tire bead reinforcing rubber layer is arranged between the carcass cord fabric layer and the sidewall rubber on the upper part of the tire bead, and is cambered; the tire bead reinforcing rubber layer is arranged on the upper part of a rim and on the lower part of the central horizontal line of the tire, and clamped between the carcass cord fabric layer and the sidewall rubber; the tire bead reinforcing rubber layer is stacked and connected with the carcass cord fabric layer and the sidewall rubber. The tire bead reinforcing rubber has the performance characteristics of good thermal stability, high elasticity and low heat generation, and meanwhile, has the advantages of relatively high tensile strength, elongation at break and 300% stress at definite elongation, and relatively low permanent deformation after dynamic compression fatigue; the aviation tire is high in load and low in air pressure; under the use conditions of large stress and high deformation of the tire bead part, the quality problems such as internal disengagement of the tire bead, splitting and tire bead blasting can be avoided, and the tire is safe to use.
