摘要： Evaluation tires, each having a plurality of structural elements including a target structural element, are prepared. Only the experimental structure of the target structural element is different among all the evaluation tires, while the structures of other structural elements are identical. Radial force variation of each of the evaluation tires is measured. Corrected radial-force variation of each of the evaluation tires is calculated by subtracting a 1st order component of the radial force variation from the radial force variation, and the structure of the target structural element is determined based on the corrected radial-force variations of the evaluation tires. This process is repeated for other structural elements.

摘要： At least one reinforcing rubber layer is provided in the part of each of two side wall portions which is on the outer side of a carcass layer. The outer circumferential end portions of the reinforcing rubber layers extend to positions in which they are disposed between the end portions of the innermost belt layer and the corresponding portions of the carcass layer, while the inner circumferential end portions of these rubber layers extend inward in the radial direction of the tire so as to overlap the bead fillers in positions on the outer sides of the end portions of the carcass layer in the widthwise direction of the tire. A 100% modulus at 100.degree. C. of the rubber constituting the reinforcing rubber layers is not higher than that of the rubber of the belt layers, and a dynamic elastic modulus at 20.degree. C. of the former rubber in the range of 10-40 MPa. The thickness of the portions of the reinforcing rubber layers which are between the edges of the innermost belt layer and the outer circumferential ends of the bead fillers is set securely to not less than 1.00 mm, and the thickness of the parts of the side wall portions which are on the tire outer sides of the reinforcing rubber layers also not less than 1.00 mm.
