Abstract:
1. A method of, for each construction vehicle to be controlled, selecting a tread pattern which is the most advantageous in terms of wear resisting period among plural different tread patterns of tire species having different volumes to be worn and each mountable to the vehicle, comprising: step A of making a vehicle, having a running position sensor for acquiring running position data and a slip rate sensor for acquiring slip rate data for at least one tire mounted thereon, run on a “registered travelling path” preset such that the vehicle runs thereon, acquiring data of a position and data of a slip rate at the position regarding plural positions on the registered travelling path, and calculating, based on the data thus acquired, a “degree of road surface slip” which represents degree at which slip is likely to occur on the registered travelling path; step B of setting a table which correlates a degree of road surface slip of the registered travelling path, with a tread pattern which is the most advantageous in terms of wear resisting period when the vehicle runs on the registered travelling path, the tread pattern being determined depending on the degree of road surface slip; and step C of applying the degree of road surface slip calculated at step A to the table to select a tread pattern which is the most advantageous in terms of wear resisting period, wherein, upon setting the table at step B, a tread pattern having a relatively small volume to be worn is correlated, as the most advantageous tread pattern in terms of wear resisting period, with a registered travelling path having a relatively high degree of road surface slip, and a tread pattern having a relatively large portion to be worn is correlated with a registered travelling path having a relatively low degree of road surface slip.
