摘要:
A tire is provided having a tire noise pitch sequence based on preferred characteristics of the tire noise generated by tire tread lug stiffness variations. The tire has preferred modulation characteristics and good level characteristics. Tire noise pitch sequences are provided for tires with different numbers of tread lugs. In one embodiment, the invention provides a tire having a body having a tread that has a pitch sequence; and the pitch sequence having five different size pitches with pitch ratios of 1.00, 1.10, 1.25, 1.4, and 1.50.
