Abstract
The tire of this invention has a belt package with a combination of a steel refinforced inner belt ply and an aromatic polyamide reinforced outer belt ply. The strength per unit width of the aromatic polyamide reinforced ply is made to be within 30 percent greater than the strength per unit width of the steel reinforced belt ply. The tire of this invention has angles of the aromatic polyamide reinforcing members from the mid-plane greater than the angles of the steel reinforcing members from the same mid-plane by 1 to 8 degrees. High impact endurance values are disclosed to be a function of the difference in bending stiffness values for each ply as well as a function of the composite shear stiffness values.
