Abstract:
A method to identify and remove machine contributions from tire uniformity measurements made on a tire uniformity machine for measuring and collecting tire uniformity measurement signals, the method characterized by the steps of:a) mounting a test tire on the tire uniformity machine;b) determining a first uniformity measurement signal of the test tire by performing first measurement of uniformity of the test tire on the tire uniformity machine;c) calculating an average machine contribution signal from the first uniformity measurement signal of the test tire;d) mounting a production tire on the tire uniformity machine;e) determining a production tire uniformity measurement signal by performing a measurement of uniformity of the production tire on the tire uniformity machine; andf) determining a corrected production tire uniformity signal for the production tire by subtracting the average machine contribution signal from the production tire uniformity measurement signal.
