Abstract
Official abstract text for this publication.
The present invention includes a run-flat tire 1 comprising a plurality of turbulence generation ridges 20 which extend on a surface of a tire side portion 3 in a tire-radial direction and which are arranged at a pitch in a tire-circumferential direction and relationship Si>So is satisfied. Si is the sum of sidewall areas of all the turbulence generation ridges located at the inner side, in the tire-radial direction, of a maximum width position of the pneumatic tire. So is the sum of sidewall areas of all the turbulence generation ridges located at the outer side, in the tire-radial direction, of the tire maximum width position.
First claim
