Abstract:
1. A method of manufacturing a pneumatic tire, the method comprising: vulcanizing the pneumatic tire, wherein a vulcanizing temperature about 1 mm in a radial direction from a surface of a rib groove formed in a single-layer tread member is set to be higher than that in a range of 0.5 mm to 1.5 mm in the radial direction from a bottom part of the single-layer tread member, so that a 300% modulus at 100° C. at about 1 mm in the radial direction from the surface of the rib groove formed in the single-layer tread member is set to be between 1.10 times and 2.0 times inclusive larger than a 300% modulus at 100° C. in the range of 0.5 mm to 1.5 mm in the radial direction from the bottom part of the single-layer tread member.
