Disclosed are a method for determining pitches of cooling fins for a pneumatic tire so that the heat dissipation performance of the sidewall may be improved and an airflow noise generated by a high speed air may be decreased, and a pneumatic tire including the cooling fins arranged by the same. The method for determining pitches of cooling fins for a pneumatic tire, including: selecting a total number of cooling fins, the number of pitch-types, and a size of each pitch; generating a random number and arranging each type of pitch sequentially by the generated random number to produce a random pitch arrangement; Fourier transforming the obtained pitch arrangement to calculate a result value (FT); and repeatedly performing the steps of producing a random pitch arrangement and calculating the FT to determine a pitch arrangement when a change in amplitude of the FT is smallest.
