Abstract
A tire profile () includes a tread (), a shoulder (), a flat portion (), an upper sidewall () and a lower sidewall (). The shoulder () is provided in contact with a tread () at a point (Pa). The flat portion () is provided in contact with the shoulder () at a point (Pb). The upper sidewall () is provided in contact with the flat portion () at a point (Pc). A system including an input portion and a calculating portion is used for designing the profile (). When the numeric values of a radius of curvature (R) of the shoulder () and an inclination angle (θ) of the flat portion () are input by the input portion, the calculating portion calculates a length (L) of the flat portion () and a radius of curvature (R) of the upper sidewall (). Based on the input numeric values and the calculated numeric values, the profile () is drawn by CAD software.
