Claim:
A pneumatic tire set comprising pneumatic tires to be attached to a rim, and noise dampers made of a spongy material which are fixed to an inner surface of the tires facing a tire cavity surrounded by the rim and the pneumatic tire and which extend in the circumferential direction of the tire, wherein each pneumatic tire in the pneumatic tire set has a single one of said noise dampers, each of the noise having the same cross-sectional shape and size and having a cross-sectional area S2 of 5.7 to 11.1% of a cavity cross-sectional area S of the tire cavity, the pneumatic tires having at least two different tire sizes in a size group of pneumatic tires including a minimum volume tire such that the cavity cross-sectional area S of the tire cavity on the meridian cross-section including a tire shaft has a minimum value Smin and a maximum volume tire such that the cavity cross-sectional area S has a maximum value Smax, and the pneumatic tires having sizes such that the cavity sectional area ratio Smax/Smin falls within the range of greater than 1.00 to 1.95.
