Title:
MUD PERFORMANCE EVALUATION METHOD FOR TIRE
Document Type and Number:
Japanese Patent JP2013044655
Kind Code:
A
Abstract:

To easily and quantitatively evaluate drivability of a tire in a muddy area.

A mud performance evaluation method is for evaluating drivability of a tire t in a muddy area. The method mud performance evaluation includes: a mud loading step for preparing a tire t1 loaded with mud obtained by loading grooves g provided on a tread surface 2 of the tire t with mud material d; a tire supporting step for rotatably supporting the tread surface 2 of the tire t1 loaded with the mud, with the tread surface apart from a ground surface R; a tire rotating step for rotating the supported tire t1 loaded with the mud; and an evaluating step for evaluating soil removal performance on the basis of a scattering state of the mud material d scattered from the grooves g by the rotation.
