Abstract: An annular antenna and transponder are affixed to a tire using the transponder as a counterweight to offset tire imbalance. The annular antenna is attached to an inner tire surface and is coupled electrically to a transponder device and is fixed relative to a housing in which the transponder device is packaged. The mass of the transponder housing is used specifically to counterbalance tire imbalance by first ascertaining the position at which a counterbalance would prove to be beneficial and then affixing the annular assembly to the tire so as to position the mass of the transponder housing at the optimal location for counterbalancing benefit.

Abstract: A method for predicting product performance uses sample data from a manufactured product under at least first and second different conditions, to establish transfer functions and a bias term simultaneously, which are then used to predict second condition properties for product when first condition properties are measured. In an illustrated embodiment, a method for predicting tire uniformity, preferably a harmonic component of force variation, preferably when operating at a high speed, is based on a tire's tested uniformity. A production tire's predicted tire uniformity is determined by a calculation using transfer functions applied to production tire measurement data obtained from factory floor testing equipment, which includes a factory floor balance checker and a factory tire uniformity machine, where the data are modified by a bias term that minimizes the machines contribution to the data.
