A 300% modulus at 100&#xb0; C. in the range of 1 mm in an radial direction from a surface of a tread member is set to be between 1.10 times and 2.0 times inclusive, more preferably, between 1.10 times and 1.5 times inclusive, larger than a 300% modulus at 100&#xb0; C. in the range of 0.5 mm to 1.5 mm in the radial direction from a bottom part of the tread member.

Pneumatic tire, and manufacturing method of the same

This invention relates to a rubber composition capable of using in a tread rubber of a tire to improve both an initial gripping performance and a running stability of the tire as compared with those of conventional tires, and more particularly to a rubber composition formed by compounding an indene-containing C-based resin having a softening point of 130&#xb0; C.-190&#xb0; C. and an indene content of 30-80 mass % into a rubber component.
