Abstract
A method for designing a pneumatic tire to have improved vibration characteristics. Dynamic testing of the tire detects a) respective frequencies of a plurality of radial vibration modes of the tire, and b) respective frequencies of a plurality of torsional vibration modes of the tire. The testing may determine that a first interval between the frequency of an even-numbered radial vibration mode and the frequency of an even-numbered torsional vibration mode is less than a first threshold, and/or may determine that a second interval between the frequency of an odd-numbered radial vibration mode and the frequency of an odd-numbered torsional vibration mode is less than a second threshold. One or more design parameter of the tire is/are modified to increase at least one of first interval and the second interval to the respective first or second threshold.
