Claim:
1. A method of manufacturing a tyre comprising the steps of: designing a tread band of the tyre, the tyre tread band comprising blocks defining a raised pattern comprising a number of longitudinal grooves and transverse grooves; determining a best longitudinal pitch of blocks of a tread band of the tyre, to minimize pass-by noise at a given target speed, according to the equation: Pb best longitudinal pitch of the blocks, Vd target speed of the tyre, fp resonance frequency of the longitudinal grooves, K integer greater than zero; arranging the blocks in the tread band in a longitudinal row along the tyre tread band based on the determined best longitudinal pitch Pb; and manufacturing the tyre with the blocks after the step of arranging.
