On-snow tire-testing method, on-snow tire-testing system, and road surface for on-snow tire tests

摘要

An artificial snow layer 83 in which artificial snow is arranged in a layered form is provided on a turntable 72, and on-snow testing is performed by rotating the turntable 72 and rotating the tire 11 on the artificial snow layer 83. The artificial snow is made from a frozen granular water-absorbent material that has been made to absorb water. The artificial snow can be reused, and on-snow testing of the tire 11 can be performed at low cost by performing testing of the tire 11 on the turntable 72. IMAGE
