Abstract: A method of predicting tread-wear for pneumatic tires, the method incorporating laboratory measurements of pressure and traction data exerted by selected tires against a surface, and the collection of actual treadwear data from road-testing of the tires in order to establish an empirical relationship of certain phenomena which affect tread-wear. The relationship is ultimately reduced to tread-wear predicting equation having parameters which are associated with tabularized numerical values collected from the data in the laboratory and on the tire test-course. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way.
