TIRE TREAD PATTERN SELECTION METHOD FOR CONSTRUCTION VEHICLE, AND TIRE TREAD PATTERN SELECTION SUPPORT SYSTEM FOR CONSTRUCTION VEHICLE USED THEREIN

摘要

A tire slip rate measuring system for construction vehicle which allows for selection of a most advantageous tire class in tire abrasion life out of a plurality of tire classes having the same TKPH based on quantitative prediction, and a tire tread pattern selection method for construction vehicle using the same. The tire slip rate measuring system (10) for construction vehicle comprises a traveling position sensor (1) mounted on a construction vehicle (11) and acquiring the traveling position data of the construction vehicle (11) continuously, a slip rate sensor (2) for acquiring the slip rate data of at least one tire attached to the construction vehicle (11) continuously, a memory (3) for storing the data acquired by these sensors, and a computation section (5) for collecting the slip rate at each point on a predetermined travelling road when the construction vehicle (11) travels this travelling road predetermined as its travelling road under dry condition based on these data stored in the memory (3), and calculating a slip rate distribution representing the frequency rate of every predetermined slip rate range.
