PNEUMATIC TIRE

The present invention discloses a pneumatic tire. The pneumatic tire includes a bead portion and a rim flange provided outside the bead portion. The rim flange is made of a rubber resistant to ozone and fatigue and a hardness reinforcing rubber portion is interposed between the rim flange and the bead portion. The pneumatic tire of the present invention avoids a change in the physical properties of the flange rubber, ozone cracks caused by ozone present in the air, and fatigue cracks caused by frequent flexion and extension to achieve improved handling stability and straight ahead ability.
