Claim One:
1. A method of electronically determining uneven mass distribution levels for a production tire based on measured radial run out values, said method comprising: electronically establishing a calibration curve for one or more test tires that correlates at least one harmonic of interest for measured radial run out to electronically calculated centripetal force; measuring on a tire measurement apparatus the radial run out for the production tire having unknown uneven mass distribution, and isolating at least one harmonic of interest from the measured radial run out; electronically mapping the at least one harmonic of interest of the measured radial run out for the production tire to centripetal force using the calibration curve; and electronically calculating the uneven mass distribution for the production tire from the centripetal force identified from said electronically mapping step; and grinding or adding extra mass to the production tire to reduce levels of uneven mass distribution identified in the production tire.
