Method of selecting tire tread pattern for construction vehicle and system for supporting selection of tire tread pattern for construction vehicle

摘要

The present invention provides a system for measuring slip rate of a tire for a construction vehicle, which system makes it possible to select based on a quantitative estimation a tire species that is the most advantageous in terms of wear resisting period among plural types of tire species having the same TKPH value and a method of selecting a tire tread pattern for a construction vehicle using the system. The system 10 for measuring slip rate of a tire for a construction vehicle includes a running position sensor 1 mounted in a construction vehicle 11, for continuously acquiring data of running position of the construction vehicle 11, a slip rate sensor 2 for continuously acquiring data of slip rate for at least one tire mounted on the construction vehicle 11, a memory 3 for storing data acquired by these sensors, and a calculation portion 5 for calculating based on the data stored in the memory 3 a slip rate distribution in which the slip rate range is divided into predetermined range sections and frequency ratios of the slip rates, measured in dry conditions at respective spots on a predetermined travelling path preset such that the construction vehicle runs, are plotted in the corresponding range sections.
