Method of designing tire and tire

The invention provides a method of designing tires and the tires. The method of designing a tire comprises a step (20) for determining a resonance frequency (f) which is generated from the tire based on the ground contact length of the tire when a regular internal pressure and a regular load are applied to the tire, a step (30) for determining the number of pitches of a block row, and a step (40) for determining the phase of the block row which is defined by the interval of arrangement between a plurality of blocks constituting the block row when the band of secondary pitch noise frequency (fp2) caused by the block row at the reference speed, i.e. the reference traveling speed of a vehicle to which the tire is attached, overlaps the band of the resonance frequency (f). At step (40), the phase of a block row is determined such that there is a 10-30% deviation between a block row and a second block row with respect to the equator line of the tire.
