Abstract
By wheel testing two tires having different construction parameters, e.g. different tire cords and measuring the temperatures at a few points within each tire body; and by measurement with a high strain dynamic viscoelastometer, the heat generation rate and dynamic tensile moduli (at various temperatures, strain frequencies and tensions) of the cords and rubber used in each tire are determined, where the values of the exponents 'X' in the general equation relating cyclic strain amplitude, S, in the tire cord and in the rubber of each tire vs. the dynamic tensile moduli, E, for cords and rubber, at given temperature can be determined in the form: S.sub.A /S.sub.B=( E.sub.B /E.sub.A).sup.X.
