The present invention relates to a pneumatic tire which satisfies the following formula if A is the sum of projected area and recessed area of a cross section obtained by cutting a side wall perpendicular to the circumferential direction of the tire: Amax- Amin<=¦A¦max (however, projected area is positive (+), recessed area is negative (-), Amax is the maximum of A, Amin is the minimum of A,¦A¦max is the maximum of¦A¦). The present invention can obtain the uniformity of circumferential rigidity as the amount of rubber to the circumference of the side wall is uniform. Furthermore, a method for forming the three-dimensional shape of the side wall by the present invention can produce the tire with excellent noise and vibration performance as the rigidity of the tire to the circumference of the side wall is uniform. |
