Sidewalls (12,13) for pneumatic tires (10) having a greater stiffness improve handling and performance of the tire. The sidewalls comprise a rubber, selected from the group cosisting of natural rubber, synthetic rubber and blendsthereof, and from about 20 to 80 parts of a rubber compatible additive, per 100 parts of rubber capable of imparting a tensile modulus of from about 30 to 200 MPa at 10 percent elongation. Pneumatic tires provided with such sidewalls are improved and exhibit higher cornering force coefficients. A method for improvingthe handling characteristics of pneumatic tires includes the step of applying sidewalls to the tire carcass during building, having a tensile modulus of from about 30 to 200 MPa at 10 percent elongation.
