Abstract
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 systemfor measuring slip rate of a tire for a construction vehicle includes a running position sensormounted in a construction vehicle, for continuously acquiring data of running position of the construction vehicle, a slip rate sensorfor continuously acquiring data of slip rate for at least one tire mounted on the construction vehicle, a memoryfor storing data acquired by these sensors, and a calculation portionfor calculating based on the data stored in the memorya 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.
