Estimation of feasible ranges of functional tire characteristics based on tire dimension, inflation pressure, and wheel load:

The functional properties of a tire contribute significantly to the achievement of the overall vehicle targets in terms of driving performance, fuel consumption, and comfort. Tire development based on functional tire characteristics enables the use of objective target values across all topics and thus contributes to a clear target agreement between tire and vehicle manufacturers. Development tires can be evaluated on the basis of test bench measurements and duration as well as financial costs can be reduced in this way. The increasingly strict and conflicting targets imposed by legal and customer-related requirements are a major challenge. In order to reach the long-term goals, methods for evaluating all requirements with regard to their feasibility are needed. Within the scope of this study, different geometrical and physical influences on the functional tire characteristics lateral grip, cornering stiffness, and lateral relaxation length are statistically analyzed on the basis of numerous test bench mea...
