<p>The kinds or types of noise dampers are significantly reduced, while securing high noise suppression performance and high uniformity of tire, to achieve improvement of production efficiency, management efficiency, transportation, storage efficiency and the like and reduction of total cost. On a tire inner surface "is" facing a tire cavity "i" surrounded by a rim 2 and a pneumatic tire 3, the tire is provided with a noise damper 4 made of a spongy material and extending in the circumferential direction of the tire. Noise dampers 4 having the same cross sectional shape are used in a size group of tires which include a minimum volume tire that the cross sectional area S of the tire cavity on the meridian cross section has a minimum value Smin and a maximum volume tire that the cavity cross section area S has a maximum value Smax, and which have sizes such that the cavity sectional area ratio Smax/ Smin falls within the range of 1.00 to 1.95.</p> |
