摘要： A pneumatic tire includes a composite assembly comprising a rubber web and a plurality of parallel cords embedded in the rubber web at spaced intervals in the circumferential directions of the pneumatic tire. The pneumatic tire is approximated with a finite element model generated by dividing the pneumatic tire into a plurality of finite elements and analyzing the finite element model according to a finite element process. A composite assembly element model is generated for the composite assembly by dividing the rubber web into rubber web elements as solid models and dividing the cords into cord elements as solid elements, according to the finite element process.

摘要： A tire characteristic judging device judges a tire characteristic in the following way. At first, a load applied to a tire and a cornering force generated in the tire in time series while the tire is rolling are acquired. Then, an applied load variation amount is calculated from the acquired time-series applied load information and a cornering force variation amount calculated from the acquired time-series cornering force information. Next, an evaluation value is calculated based on the applied load variation amount and the cornering force variation amount. The calculated evaluation value and a preset reference value are compared with each other and whether or not the tire satisfies a desired characteristic is judged according to a result of comparison.

摘要： The tire transient response data obtained while cornering with a slip angle is calculated based on a tire dynamic model. The deformation response of a tread part in the tire dynamic is set as a first-order-lag response. The value of the transient response parameter is initialized in order to define the first-order-lag response. The time-series data of the transient response of the slip angle between the tread part and the road surface in the tire dynamic model is obtained by computing the convolution integral of the defined response function of the first-order-lag response with a time gradient of the time-series data of the slip angle. The value of a lateral force is calculated by using the tire dynamic model based on the time-series data of the transient response of the slip angle thus obtained. Accordingly, the transient response data is calculated and the value of the transient response parameter is obtained.

摘要： A pneumatic radial tire including a belt reinforcing layer or layers formed by spirally continuously winding a single organic fiber cord in a manner such that before the molding of an unvulcanized tire, the belt reinforcing layer or an outer or outermost belt reinforcing layer has a greater density of winding of the organic fiber cord in its regions located beneath or inner to a main groove-forming rib of a mold than in its remaining region, whereby after the molding of the unvulcanized tire, the cord density in the regions of the belt reinforcing layer or the outer or outermost belt reinforcing layer beneath or inner to the main groove-forming rib is set to be substantially identical with the cord density in its remaining region; and a process for the production of such tire.
