Abstract
In order to improve ride quality and steering stability, the present invention provides a pneumatic tire having a sidewall made of a rubber composition for a sidewall comprising at least a natural rubber and a diene rubber comprising a syndiotactic 1,2-polybutadiene, wherein rubber sheets obtained by extruding at a thickness of at most 1.5 mm the rubber composition for a sidewall with a complex modulus E*a in a tire circumferential direction measured at a temperature of 70° C. and a dynamic distortion of 2% of 3 to 15 MPa are laminated.
Claims2
A pneumatic tire having a sidewall made of a rubber composition for a sidewall comprising a rubber component comprising at least a natural rubber and a diene rubber comprising a syndiotactic 1,2-polybutadiene,
- wherein the sidewall is prepared by laminating rubber sheets obtained by extruding, at a thickness of at most 1.5 mm, the rubber composition for a sidewall with a complex modulus E*a of 3 to 15 MPa in a tire circumferential direction measured at 70° C. at a dynamic distortion of 2%.
