摘要： A pneumatic tire has two belt layers, each having a plurality of strip pieces formed by pulling together and rubberizing a plurality of steel cords. Strip piece width, strip piece thickness, belt layer cord angle with respect to a tire circumferential direction, numbers of the strip pieces of inner and outer belt layers, and circumferential lengths of the inner and outer belt layers are respectively denoted by A, G, θ, N1, N2, L1 and L2. N2 is equal to N1, and N1 is an integer satisfying L1=N1×A/sin θ. The inner belt layer is formed by joining the N1 strip pieces so each side of each strip piece is butted with one side of another strip piece. The outer belt layer is formed by aligning the N2 strip pieces on the inner belt layer in the tire circumferential direction with spaces of width 2πG/N2 disposed between adjacent strip pieces.

摘要： In a tire designing method, at least one of a tire profile shape, a shape of a tire component member and physical property data of the tire component member is tentatively selected as a parameter to prepare an initial tire model (30) representing the pneumatic tire by using a finite number of elements, and at least one of a stress acting on the initial tire model by the inner pressure filling processing and the physical property data used for the initial tire model is modified corresponding to a predetermined measure of elapsed time, to thereby deform the initial tire model and a tire profile shape after a change with time is predicted by using the deformed initial tire model. By preparing the tire model (30) with the predicted tire profile shape and applying the inner pressure filling processing and road contact processing thereto, the maximum principal strains in the elements of the tire model (30) are calculated, and the margins of safety of the tire component members are calculated by using the maximum principal strains. The tentatively selection is repeated until the calculated margins are equal to or larger than a pre-set reference margin of safety so that a tire with excellent durability can be designed.

摘要： A method for tire parameter derivation, tire cornering characteristic calculation and tire design is used with a tire dynamic model constituted by using a plurality of tire dynamic element parameters including stiffness and friction coefficient and parameter defining a distribution of contact pressure of the tire. The parameters and tire cornering characteristic are derived by using the combined sum of squared residuals being obtained by weighted addition of a first sum of squared residuals of lateral force and a second sum of squared residuals of self-aligning torque. The tire dynamic model is a model for calculating a lateral force and for calculating a self-aligning torque separately as a lateral force-based torque component generated by the lateral force applied on a contact patch of the tire and a longitudinal force-based torque component generated by a longitudinal force applied on the contact patch of the tire.
